Falling Birth Rates In Japan

Birth rates in Japan to Japanese nationals are falling much more quickly than expected, and Japan has, so far, resisted allowing significant immigration. Policy efforts specifically targeted at increasing birth rates, with measures like economic incentives for parents, have a very poor record of success globally.
Japan must stop being overly optimistic about how quickly its population is going to shrink, economists have warned, as births plunge at a pace far ahead of core estimates.

Japan this month said there were a total of 686,000 Japanese births in 2024, falling below 700,000 for the first time since records began in the 19th century and defying years of policy efforts to halt population decline. The total represented the ninth straight year of decline and pushed the country’s total fertility rate — the average number of children born per woman over her lifetime — to a record low of 1.15…

The median forecast produced by the National Institute of Population and Social Security Research (IPSS) in 2023 did not foresee the number of annual births — which does not include children born to non-Japanese people — dropping into the 680,000 range until 2039.

Progress For Laser Defenses

The U.S. Navy has a prototype grade 400 kW laser, which is a significant improvement on past efforts. Ideally, a laser can destroy incoming drones, shells, and missiles at a minimal cost per shot with an ammunition supply that never runs out. The more powerful the laser, the less time it needs to keep its beam on target to sufficiently damage to target to prevent it from striking. 

Public records about these weapons have been coy about just how much time on target is needed, how far away the target can be, and what countermeasures or atmospheric conditions can prevent it from working. So, it is hard to know if it is ready for prime time yet. And, 400kW still isn't really all that powerful. That's just the power of a fairly powerful commercial electric car or truck (it is equivalent to about 300 horsepower). But, there is little doubt that more power is better, even though scaling up the power of a military laser presents serious technical challenges. If we can get to a ready to deploy 400kW defensive laser by 2026, perhaps we can get a megawatt defensive laser on line by 2030.

When it is ready for prime time, this active defense could be revolutionary, and could (together with electronic warfare methods and electromagnetic pulses to disrupt guidance systems and kinetic interceptors and new lighter armor materials) end the one shot, one kill era of smart bombs, guided missiles, and one way armed drones that persisted for about thirty years, in a major victory for defense, after a sustained period of time in which offenses have largely overcome armor and maneuverability.

Ships and point defenses for forward operating bases are a natural place to start, because the size and weight of the system isn't too critical. This could be the difference between large surface warships being viable or not, a vulnerability that the Secretary of Defense is well-aware of himself (not that anything he says should be given too much credibility, particularly since his budget is driven to a great extent by fear of a Chinese military threat):

In a rare admission, US Defense Secretary Pete Hegseth has said that the Chinese hypersonic missiles can destroy all US aircraft carriers in just 20 minutes.

“So far our [US] whole power projection platform is aircraft carrier and the ability to project power that way strategically around the globe,” said Hegseth in a recent interview.

However, Hegseth added that China’s 15 hypersonic missiles “can take out 10 aircraft carriers in the first 20 minutes of the conflict,” added Hegseth. . . . 
According to a US Department of Defense (DoD) report published in December 2024, China’s hypersonic missile technologies have greatly advanced during the past 20 years. Many PRC missile programs are comparable to other international top-tier producers.

China’s deployment of the DF-17 hypersonic glide vehicle (HGV)-armed medium-range ballistic missile (MRBM) will continue to transform the People’s Liberation Army’s (PLA’s) missile force, the DoD added. The system, which was fielded in 2020, may replace some older short-range ballistic missiles (SRBM) units and be used to strike foreign military bases and fleets in the Western Pacific. The DF-27 may have an HGV payload option in addition to conventional land-attack, anti-ship, and nuclear payloads. Official Chinese military writings indicate this range class spans 5,000–8,000 km (3,107–4,971 miles), designating the DF-27 as an intercontinental ballistic missile (ICBM), and the local media indicates that it can potentially range as far as Alaska and Hawaii. On July 27, 2021, China tested an ICBM-range HGV that traveled 40,000 km (24,854 miles).

In April 2019, the PLA Navy revealed during its 70th-anniversary celebration that its new guided-missile cruiser can employ long-range, land-attack cruise missiles and, in 2022, launched the YJ-21 hypersonic missile designed to defeat aircraft carriers.

According to the DoD, China has the world’s leading hypersonic missile arsenal and has dramatically advanced its development of conventional and nuclear-armed hypersonic missile technologies.

But imagine a system like that retrofitted into a C-17 or a B-52, that would go from having no defense but flares, to being able to destroy multiple incoming anti-aircraft missiles in flight before they do any harm, or to a military satellite that could destroy missiles intended to destroy it before they hit.

According to the contract announcement, the goal is to design, integrate, and test a high-powered directed-energy subsystem suitable for deployment aboard naval vessels and potentially land-based platforms.

At the heart of the effort is creating a 400-kilowatt-class laser weapon. This will be achieved by combining multiple 50-kilowatt laser modules into a unified beam supported by a precision beam-control assemblySuch a design is key to scaling laser systems to higher powers without compromising beam quality or accuracy.

The technology is being pursued for defensive purposes, like shooting down drones, missiles, and potentially hypersonic weapons, as well as other military uses, including remote sensing and battlefield illumination.

While the Pentagon has disclosed few technical details, industry experts note that this level of directed-energy output would represent a major leap in laser weapon capabilities. By comparison, most current operational laser systems deployed by the Navy, such as the Laser Weapon System (LaWS), have outputs of around 30 to 100 kilowatts.

A 400-kilowatt system would potentially allow US forces to intercept faster and more robust targets at greater distances, burning through drone bodies or missile casings within seconds of contact.

From Interesting Engineering.

Less obviously, high powered lasers might provide naval ships with intermediate options between sinking an opponent's ship and doing nothing, a challenging task when, for example, the Chinese Coast Guard or paramilitary merchant marine ships harass Filipino fishing vessels, and a naval escort vessel would like them to stop without causing an international incident.

A 400kW laser isn't going to sink a seaworthy ship in most cases. But it could inflict controlled and measured damage, like destroying the offending ship's radar, or some of its communications equipment, or one of its hydraulic control lines, or it reconnaissance drones, or one of its weapons, that would encourage the offending ship to back off. And, it could do so with minimal risk of causing collateral or otherwise unintended damage.

The Imperfect Case That The Army Is Too Light

An argument that the Army is too light gets some points right, but others deeply wrong. 

How can we have forgotten the terrible lessons of the early 2000s, when losses in Iraq and Afghanistan prompted a scramble to deploy up-armored HMMWVs and Mine Resistant Armor Protected Vehicles? Today’s Army, far lighter than the one that took such damage in so-called “low-intensity combat,” is ill-equipped to deter or contend with the likes of China or Russia.

Let’s take roll of the Army’s 31 active maneuver brigades. Eleven are heavy brigades equipped with tanks and infantry fighting vehicles—well-protected platforms suited to modern war.

Another six brigades are Stryker formations equipped with their eponymous lightly armored, wheeled infantry carriers. Originally called the “interim armored vehicle,” the Stryker was intended to serve only until the arrival of the Future Combat Systems, which imploded instead. From conception, Stryker units have suffered from doctrinal and conceptual confusion. Stryker units carry more dismounted troops than Bradley units, which are intended to fight primarily mounted. But they are infantry carriers, not infantry fighting vehicles. With poor off-road mobility, they are vulnerable to hand-held anti-armor systems, and their units have towed rather than self-propelled artillery. Repeated National Training Center rotations show they cannot survive when employed against armor.

The remaining 14 active maneuver brigades are light infantry formations, cheaper and easier to deploy but, realistically, unable to compete with today’s threat. Under current guidance, they go to war in “infantry squad vehicles”—essentially, unarmored dune buggies without heavy weapons.

Compounding the problem, the commanders of these light brigades have dramatically less firepower than they used to. The recent decision to eliminate the air cavalry squadron from the aviation brigade in Army divisions removes half of each division’s 48 AH-64E attack helicopters, a massive reduction in combat power. Only slightly less dangerous was the Army’s recent decision to deactivate the cavalry squadron in Stryker and light infantry brigades, with their many wheeled vehicles and heavy weapons. The same directive stripped light infantry battalions of their antiarmor/heavy weapons companies: mounted formations armed with automatic grenade launchers, heavy machine guns and heavy antitank systems. These actions removed much of the brigade’s available firepower.

Meanwhile, light artillery battalions still use the venerable M119 105mm towed howitzer, which has a lower rate of fire, shorter range, and weaker weapons effects than the 122mm and 152mm systems used by Russian and Chinese brigades. They are also slower to displace than self-propelled systems, making them far more vulnerable to counter-battery fire and drone attacks.

Promises to offset all these reductions with “Unmanned Systems and Ground/Air launched effects” raise serious questions, given the lack of specifics provided and DoD’s poor acquisition track record.

A quick look at adversary force structure illuminates the challenge. Russian maneuver brigades (tank, motor rifle, airborne/air assault, naval infantry) are remarkably similar. All include four maneuver battalions; three artillery battalions (both tubed and rocket); anti-tank, air defense and reconnaissance battalions; and an electronic warfare company. Chinese brigades have four maneuver battalions supported by strong artillery, air defense and EW units. U.S. brigades have three maneuver battalions, a single artillery battalion, and no dedicated anti-tank, air defense, or EW units. At higher echelons, adversary artillery, air defense and EW continues to outmatch U.S. capabilities, and both the Russian and Chinese militaries have evinced strong commitments to advance their drones and unmanned systems. Overall, their forces are clearly stronger, a dilemma only exacerbated by repeated moves to lighten or weaken U.S. ground forces.

What should the U.S. Army do? Several things: re-equip light brigades with protected, wheeled transport mounting heavy weapons, as before; restore their antiarmor companies; increase the density of Javelin anti-tank and Stinger air defense systems across light formations; replace towed light artillery with wheeled, 155mm systems like the French Caesar or German RCH-155; reverse the deactivation of divisional air cavalry squadrons; and arm divisional UH-60 assault helos with the Hellfire antitank missile system.

Stryker brigades should be converted into true heavy brigades, perhaps with reconditioned M1 Abrams tanks and M2 Bradley fighting vehicles that are now in storage. Hundreds of earlier variants of the M1, M2, and M109 self-propelled howitzer are stored at Sierra Army Depot in Nevada. Should Stryker brigades be retained, they should include an armor battalion, similar to Russian motor rifle brigades. Heavy brigades should be upgraded with the M1A3 Main Battle Tank and M2A4 Infantry Fighting Vehicle as soon as possible.

Army divisions should field a general support 155mm artillery battalion in addition to the artillery battalions providing direct support to the maneuver brigades. All brigades and divisions should include air defense and electronic warfare units, as well as dedicated drone formations with trained operators at every echelon from company to division.

America has not fought a high-intensity war against heavy forces since the Gulf War, when it enjoyed crushing superiority in all domains. Today that superiority now longer exists.

Touted as a move away from a GWOT-focused Army to one more focused on “lethality” and better suited to the Indo-Pacific region, current changes in fact cut deeply into the Army’s ability to hit hard and mass combat power. An America optimized to fight in only one theater is an America content to be a regional but not a global power—a recipe for decline. In the real world, challenges erupt suddenly and unexpectedly (think December 1941, June 1950, October 1963, August 1990 and September 2001). True national security requires a flexible and adaptive Army trained and equipped for sustained, intense combat at the high end of the spectrum of conflict. This means mobility, protection and firepower in all Army formations.

In a word, light is not lethal. It’s time for a rethink.

From Defense One.

What does this analysis get right?

Sufficient armor to protect troops against small arms fire and IEDs does make sense. The “infantry squad vehicles”—essentially, unarmored dune buggies without heavy weapons, indeed don't make sense. They utterly unprotected against even rain or hail or dust or snow or children throwing rocks. They have no weapons of their own and don't have storage capacity to carry squad scale heavy weapons or medical supplies. And, they concentrate a whole squad in a tiny space where a single grenade or volley of automatic weapons fire or IED can kill all of them in one blow. It isn't particularly capable off-road (unlike, for example, the Humvee). The only thing that recommends an infantry squad vehicle at all is that it is faster than walking. Using that as the core model for 14 of 31 Army Brigades is indeed nuts. Maybe one or two brigades of them for paratrooper type deployments into very lightly armed theaters might make sense, but these are, indeed, far too light for almost any conceivable conflict. 

These units aren't even really heavy enough to take on civilian drug cartels (as President Trump has urged the Army to make a priority). U.S. police SWAT teams routinely use more armor and heavier weapons to take on tiny domestic drug dealing gangs in U.S. cities, and protesters without firearms, or a single violent boyfriend and husband or mass shooter with a handful of small arms none of which is more than 0.45 caliber.

Cutting close air support from helicopters with missiles doesn't make much sense either.

But, how can you think that the future of near peer ground warfare lies with heavy tracked tanks and infantry fighting vehicles after having seen how the Ukraine War has played out. The author of this piece forgets that the U.S. Army deliberate fielded few main battle tanks in Kosovo due to its mountains, and that it took many critical weeks to ship them by boat and train to the front in all of the conflicts in which the U.S. has been involved since the Gulf War, despite the fact that the pace of modern warfare has not gotten slower.

Strykers and MRAPs were adequate in the main U.S. wars since the 2000s, the firepower of the main M1 Abrams tank has not been very useful, tank v. tank warfare is basically no longer a thing, and guided missiles like anti-tank Javelin missiles, Hellfire missiles, and TOW missiles have all delivered much more firepower per pound, with greater precision, at equivalent or longer ranges than the main guns of tanks. Traditional tanks like the existing Abrams and traditional infantry fighting vehicles like the Bradley, have no air defenses and no anti-drone weapons, are challenging to operate in tight urban warfare and mountain warfare settings, and aren't particularly mine resistant.

Another lesson of the wars that the U.S. has fought in the last 25 years is that off-road capabilities, where tracked vehicles are a bit faster than off-road capable wheeled vehicles, are rarely used in practice. But the tracks vehicles slow down their entire units, and because they are profoundly less fuel efficient, require more, completely vulnerable fuel tanker trucks to be sent to supply them (and those tanker trucks can't go to the off-road places that the tracked vehicles can). In wars where the front lines are often ill-defined, this is a huge problem.

As for howitzers, either towed or self-propelled, tracked or wheeled, there are also problems. Their range is only 12-24 miles. They are very heavy relative to their firepower. And, they aren't very accurate, so its takes multiple rounds to destroy a target. Mortar systems are even worse in basically every respect. Guided missile systems like HIMARs, or like or Hellfire and Javelin and TOW missiles, produce equal or greater results, with much more accuracy, at longer ranges which enemy artillery can't reach.

We need a middle ground. Yes, Army units should have heavy and lethal weapons like grenade launchers/canons, heavy machine guns, anti-tank missiles, and anti-aircraft missiles. But, for just about anything more than 50mm rounds, guided missiles or handheld recoilless rifles (e.g. for breaching bunkers or fortifications) are superior to tank shells and artillery shells.

Also, yes, they should mostly have sufficient armor to protect against shrapnel and small arms fire, and provide force protection to resist land mines and IEDs. But trying to use heavy armor to protect military vehicles against dedicated anti-armor weapons is generally futile. In Ukraine, every single type of armored tank or infantry fighting vehicle, former Soviet and Western alike, has taken extremely heavy losses no matter how strong their armor was. Against these threats, the options are to either run and hide so as not to get hit, or to employ active defenses like Israel's Trophy system, or lasers, or ground based versions of the Navy's Phalanx close in weapons system, or electronic warfare tools that disrupt the guidance systems of cruise missiles and drones.

And, finally, except in extremely niche roles in very small numbers, wheeled vehicles are superior to tracked vehicles. They are lighter. They can still handle many off-road condition. They are much faster. And, they are much more fuel efficient.

A new off the shelf JTLV, which weighs about half of the original M2 Bradley (which means that you can deploy them in twice the numbers in the same time and with C-130 aircraft that can't transport a Bradley), has about the same fire power as the Bradley, and is similarly or more protective against forces without anti-armor weapons. Both are equally vulnerable to forces with anti-armor weapons. And, the JTLV is 50% faster and has a much lighter logistics trail (it needs much less fuel per mile than a tank or a tracked infantry fighting vehicle) and is cheaper. Yes, it carries fewer infantry to dismount, but this is made up for by allowing units to field twice as many of them.

Looking at how Strykers perform against armor is a straw man argument. Strykers aren't meant to primarily be tank destroyers, any more than it makes sense to send masses of dismounted infantry up against a machine gun nest for no cover. Their carried soldiers need anti-armor weapons (like the Javelin missile, or TOW missiles) that have a range longer than the range of a tank, or other systems to support them, like helicopters or drones armed with anti-tank weapons need to be deployed as tank destroyers.

Current U.S. military doctrine is based upon the assumption that U.S. forces will quickly gain air superiority, and will then use that air superiority to destroy enemy armor and artillery, before U.S. ground forces move in. Strykers aren't supposed to enter the field of battle until the armor, that they indeed don't fare well against head to head, are dispatched, and especially not a close range without at least anti-tank weapons for their dismounted infantry.

The Ukraine War, Houthi attacks on shipping, and recent clashes between Israel and Iran, however, have demonstrated that gaining air superiority and dominance may not be possible in every case, particularly against longer range guided missiles and one way armed drones. Traditional anti-aircraft weapons, meanwhile, are optimized against manned helicopters and fixed wing attack aircraft, not numerous cheap, deadline guided munitions that blur the line between armed drones and guided missiles. Against a "near peer" force, slow and heavy main battle tanks and infantry fighting vehicles, with big, vulnerable logistics trains are targets and not assets.

The U.S. Army does need to increase air defenses and drone defenses across the force. And, the U.S. military should seriously consider switching out more vulnerable and slower attack helicopters as close air support providers, for more robust and faster dedicated close air support aircraft to replace the A-10, and drones, in addition to traditional fighter aircraft designed primarily for air to air combat, and bomber aircraft, at high altitudes, dropping "smart" bombs.

The U.S. Marine Corps has learned these lessons. It has ditched its tanks and howitzers, but kept integrated fixed wing fighter aircraft and armed helicopters to support them. 

The U.S. Army hasn't yet fully woken up to these realities and is still trying to fight World War II and the Korean War.

The Foreseeable Conflicts

It also bears noting that wars against China and Russia, which the author identified as the threats against which the U.S. Army needs to be prepared, are two very different things. 

Plausible Russian Scenarios

The Ukraine War has given us a sneak preview of what a war in Europe with Russia would look like. The Ukraine War also means that Russia's resources to fight a large scale conventional war will have been profoundly reduced. And, any plausible conflict with Russia would be fought not by the U.S. alone, but with all of its European NATO allies. 

Tanks have been destroyed at high rates by both sides in that conflict and their main guns have been very unimportant in that fight. 

Conventional howitzers received heavy use early on, because that is what was available to Russia and Ukraine at first. But now, 70%-80% of the damage is done with armed drones, missiles, snipers, and machine guns do a fair amount of the rest of the damage, and while artillery does still play a significant role in that conflict (because the supply of drones and guided missiles is more limited) it is steadily decreasing as artillery batteries are destroyed (the Russian's have lost more than two-thirds of their's so far and lose more almost every day), while supplies of drones are being replenished (since replacing lost howitzers is much more difficult). Further, artillery resources have not given either side enough of an edge to budget the current territorial front lines for years. 

And, if the U.S. and NATO, unlike Ukraine, were able to overwhelm and defeat Russian air defenses (which their guided munitions, satellite intelligence, stealth aircraft, and medium range artillery missiles would all help facilitate), Russia would be in a much worse position in terms of conventional warfare. Still, one might try to argue despite this for heavier U.S. Army forces.

Plausible Chinese Scenarios Don't Heavily Implicate The Army

In contrast, there is no sensible scenario in which U.S. forces invade any significant part of mainland China with a plan to hold it and rule it for any significant length of time.

The U.S. missions in the Indo-Pacific theater, vis-a-vis China, are to (1) protect Taiwan from being invaded, (2) protect the Philippines from maritime harassment or subjection by China, (3) to protect Hawaii, Alaska, and the U.S. territories in the Pacific (e.g. Guam and the Northern Mariana Islands) from invasion or embargoes, and (4) to protect Japan and South Korea and other allies in the region from Chinese attacks or intimidation.

A threatened invasion of Taiwan is the dominant concern among those possibilities. And, mostly, the U.S. role would to be employ the U.S. Air Force, the U.S. naval aviation, U.S. surface combatants with anti-ship missiles, U.S. attack submarines, and naval and air force resources from Japan, South Korea, and Australia, and possibly other U.S. and Taiwanese allies, to sink as many invading Chinese ships and destroy as many Chinese aircraft as possible, in support of Taiwanese forces on the ground, and to destroy the facilities on the coast of China from which those forces are deployed without occupying them on a medium or long term basis. 

The U.S. Marine Corps, based in places like Okinawa and Guam would play the leading role in reinforcing Taiwanese ground troops on the island of Formosa and nearby islands. In part, this is because the U.S. Army with the help of U.S. Air Force  and allied transport planes going into a contested airspace, and painfully slow U.S. Navy transport ships going into a contested maritime space, wouldn't be able to arrive in meaningful numbers in sufficient time to make a difference (especially their heavier forces which would have to come from South Korea, Hawaii, Alaska, and the West Coast of the mainland U.S.). 

And, invading Chinese forces that did manage to make it to Taiwan, would most likely be light infantry, because all or almost all of the ferries carrying heavy Chinese armor would likely be sunk by a barrage of air, sea, and land sources missiles, torpedos, and sea mines while crossing the 100 mile straight to Formosa from the Chinese mainland. U.S. special forces or Marines might briefly set foot on the Chinese mainland to destroy an airport or a port or a military base or to disrupt the supply chain of the Chinese forces, but they would most likely bug out as soon as their narrow and destructive mission was accomplished.

Taiwanese forces would be doing the heavy lifting to fight any Chinese forces that managed to cross the straight and in dealing with inbound Chinese missiles and armed drone with whatever anti-drone and anti-missile defenses they could muster. In any conflict where U.S. Army ground troops were doing more than just tipping the balance slightly in an evenly matched fight between invading PLA troops and Taiwanese defenders, their role would be a lost cause, and would need to happen in a matter of days, before PLA victory became a fait accompli. Artillery or tank duels between the U.S. Army and the PLA are highly unlikely.

All of which is to say that the Army's case that its forces need to be heavy armored forces to engage in a ground war with China doesn't stand up to close scrutiny. Even if the Army is able to secure the long range fires with a 1,000 mile range that it is seeking in defense procurement fights, that wouldn't matter. Hawaii is about 5,250 miles away from Taiwan. Alaska and the U.S. mainland are farther away. 

South Korea is about 830 miles away from Taiwan (about 28 hours or more by U.S. Navy transport ships once at sea through highly contested waters) and this distance would put it barely within striking distance with missiles with ranges almost three times as great as its current longest range option (which is in short supply). This is also too far for the Army to deliver its troops by helicopter without midair refueling in the face of very vigorous Chinese air defenses.

Okinawa, which has mostly Marines and Air Force and Navy personnel, is 400 miles away from Taiwan (which is still 13 hours away on an amphibious assault ship through hotly contested waters). Guam is about 2,750 miles from mainland China and has naval and air bases, but no meaningful Army or Marine Corps presence.

There are no U.S. military based on Taiwan itself, so it has almost no prepositioned troops or heavy military equipment there, and it doesn't have the depth of a relationship with local military forces that it does in Japan and South Korea either.

Plausible Scenarios Against North Korea

Really, the only plausible scenario in which U.S. Army forces would be engaged in ground combat with heavy opposing forces in Asia would be in North Korea, defending South Korea together with its own forces and with support from Japan and from other branches of the U.S. military. This would be a profoundly different kind of conflict than the conflicts against China or Russia that the author references.

North Korea may be armed to the hilt, but it is still a small country and its forces are hollow. And, it would be facing adversaries who had been planning for this moment for decades.

The Second Division of the U.S. Army, which is the main U.S. combat force stationed in South Korea (in addition to about 8,000 airmen), is divided between an artillery brigade with armored, tracked M270 multiple rocket launchers, and a combat aviation brigade with a mix of Apache AH-64 gunships, an assault regiment of troops deployed in UH-60 Blackhawk helicopters, and a regiment of general support transport helicopters, as well as some larger reconnaissance and armed drones.

The Seventh Air Force stationed in South Korea consists of two fighter wings with three squadrons of F-16 fighter aircraft and one squadron of A-10 attack aircraft.


There are about 300 sailors at a U.S. naval base in Busan, which is about 4,860 miles from Hawaii (about 162 hours by naval transport ship, in addition to time to travel from Busan to the DMZ over land). So, it would take more than a week to get more U.S. Army soldiers and equipment to South Korea that could not be air lifted (although the Marines in Okinawa would be much closer, about 25 hours by ship to Busan plus addition time to the front over land).


There are about 100 Marines and about 100 special operations forces and 20 Space Force "guardians" at the Army base there (Camp Humphreys) that also houses the 20,000 U.S. Army soldiers who are not special forces, and the U.S. Air Force base with 8,000 airmen.
Camp Humphreys is 40 miles (64 km) south of the former base in Seoul and about 60 miles (97 km) from the Demilitarized Zone that divides North and South Korea. That puts the base about twice as far from North Korea as its predecessor, one of the main reasons for the move. While the new location moves the bulk of U.S. troops out of the range of North Korean artillery, the North Korean military has developed large caliber rockets and ballistic missiles, as well as a nuclear capability, capable of reaching Camp Humphreys.

Camp Humphreys is 143 miles from Busan Naval Base, which is less than three hours away for wheeled vehicles (or by train) and less than four hours away for tracked vehicles by road. It would take another hour to the DMZ for wheeled vehicles and another hour and twenty minutes for tracked vehicles by road. So, it would be a full seven days of travel from Hawaii to the front by sea, assuming that no detours were necessary to avoid attacks in contested maritime waters, and however long it took to load and unload the forces onto their sealift, to make sealift arrangements, and to decide to deploy them. 

The Marines from Okinawa make take a couple of day to arrive by sea with heavy equipment and reach the front.

Three Launchers, One Set Of Missiles

The U.S. Army has a tracked long range heavy missile launcher, and a lighter wheeled one. It also now apparently has an experimental version that launches the same missiles out of a shipping container. These extend well beyond the 12-24 mile range of most cannon artillery and is much more accurate.

A containerized launcher designed to fire the same suite of artillery rockets and ballistic missiles as the M270 Multiple Launch Rocket System (MLRS) and M142 High Mobility Artillery Rocket System (HIMARS) has appeared at the U.S. Army’s Fort Bragg in North Carolina [top image]. The ability to launch ballistic missiles, in particular, from what is outwardly indistinguishable from any other shipping container, presents a flexible strike capability that is harder for opponents to spot. Ukraine’s recent Operation Spiderweb covert drone attacks highlighted to a dizzying degree the value of even lower-end concealed fires capabilities.

The launcher inside the container is visible off to the side in a video, seen below, from President Donald Trump’s visit to Fort Bragg today, which was posted online by White House Deputy Chief of Staff Dan Scavino. Trump was given demonstrations of various Army capabilities at the base’s Holland Drop Zone, including the launch of artillery rockets. A separate launcher, the type of which is not immediately clear, was used to fire those rounds. . . .

What is clear is that the containerized launcher, the entire roof of which is designed to open to one side, can accommodate two of the same ammunition ‘pods’ used as the tracked M270 MRLS and wheeled M142 HIMARS launch vehicles. Pods are available that come loaded with six 227mm guided artillery rockets, a single Army Tactical Missile System (ATACMS) missile, or two Precision Strike Missiles (PrSM). ATACMS and PrSM, the latter of which is beginning to enter Army service now to replace the former, are both short-range ballistic missiles.

Current-generation 227mm artillery rockets in Army inventory can hit targets some 50 miles (around 80 kilometers) away, and a variant with a maximum range of just over 93 miles (150 kilometers) entered production last year. The longest range variant of the ATACMS short-range ballistic missile in Army service today can reach targets out to 186 miles (300 kilometers).

The initial version of PrSM, also known as Increment 1, has a range of 310 miles (500 kilometers), but there are also plans to extend that out to 620 miles (1,000 kilometers) or more. It’s worth noting that a PrSM with a range beyond 620 miles/1,000 kilometers would be categorized as at least a medium-range ballistic missile. The Army is also developing an anti-ship variant of PrSM with a new seeker and is eyeing further versions with “enhanced lethality payloads” that could include miniature smart bombs and kamikaze drones.

The Army is also currently exploring new pods loaded with smaller rockets that could expand the magazine depth of M270 and M142 launcher vehicles, but at the cost of a reduction in range. The service has been experimenting with new launcher vehicles that can fire this same family of munitions, including uncrewed types and a design offering significantly expanded ammunition capacity.

Being able to launch this array of rockets and missiles already gives M270 and M142 immense flexibility. A containerized launcher would open up additional possibilities, including the ability to turn any truck that can carry a standard shipping container into a platform capable of firing long-range guided rockets and missiles. This, in turn, could help the Army more readily expand its available launch capacity as required.

The containerized launchers could also be deployed in a fixed mode, offering forward operating bases the ability to hold targets at risk dozens, if not hundreds, of miles away. This can include providing an on-call form of organic air/fire support for troops operating far from the forward base. The launcher inside the container cannot traverse laterally, but an array of them could be positioned in such a way to provide maximum coverage in all directions.

Being a container-based design, whether deployed in a truck-mounted or fixed configuration, they would be readily relocatable from one location to another. The containerized launchers could also be loaded on rail cars and/or employed from ships with sufficient open deck space.

In any of these modes, the launcher would benefit from its unassuming outward appearance. This would present challenges for opponents when it comes to detection and targeting, since any container could potentially be loaded with rockets or ballistic missiles. As already mentioned, Ukraine just demonstrated the value of concealed launch capabilities in its unprecedented covert drone attacks on multiple Russian air bases. Other countries, including Russia, China, and Iran, have also been developing containerized launch systems for artillery rockets and/or missiles.

In terms of naval use, specifically, it’s also worth mentioning here that the U.S. Navy is already in the process of fielding a different containerized missile launcher, designed to fire Tomahawk land-attack cruise missiles and SM-6 multi-purpose missiles, in shipboard and tractor-trailer configurations. The Navy launcher is based on the Mk 41 Vertical Launch System (VLS) found on various American and foreign warships, and is directly related to the Army’s ground-based Typhon system that can also currently fire Tomahawks and SM-6s.

A linked article discusses the smaller proposed rockets:

A new five-inch (127mm) artillery rocket Lockheed Martin is developing for the U.S. Army primarily as a low-cost training round could evolve into an operational munition. The service already wants to increase the magazine depth of its existing Multiple Launch Rocket System (MLRS) and High Mobility Artillery Rocket System (HIMARS) launcher vehicles, which can currently fire various 227mm rockets and short-range ballistic missiles. This is part of a larger Army push to expand its overall rocket artillery capacity.

The new Joint Reduced Range Rocket (JR3) was showcased at the Army’s recent Project Convergence-Capstone 5 (PC-C5) test exercise at the National Training Center (NTC) at Fort Irwin, California, earlier this month. Raytheon (now formally known as RTX) also notably fired at PC-C5 a JR3 from a new uncrewed launcher vehicle it has been working on in cooperation with Forterra and Oshkosh Defense. The Army also released a picture from PC-C5, seen at the top of this story, showing its existing crewless Autonomous Multi-domain Launcher (AML), which is derived from the HIMARS, firing what looks to be a JR3. The AML and Raytheon’s new design are based on 6×6 Family of Medium Tactical Vehicles (FMTV) and FMTV A2 truck chassis, respectively. . . .
In addition to being cheaper than full-up live rounds, reduced-range practice rockets allow units to make use of a greater number of more constrained ranges for live-fire training. The current slate of precision-guided 227mm rockets that existing MLRS and HIMARS launchers can fire have maximum ranges of between around 40 and 50 miles (65 and 80 kilometers). New types with ranges closer to 100 miles (150 kilometers) are also in development. Those same launchers can also fire Army Tactical Missile System (ATACMS) and Precision Strike Missile (PrSM) short-range ballistic missiles that can hit targets hundreds of miles away. The range the Army is targeting for the new JR3 is unclear, but existing LCRRPRs have a maximum reach of around 10 miles (16 kilometers). . . . .
Though designed primarily for training use, the JR3 has a modular design and Lockheed Martin has already talked about the potential for future variants or derivatives to be configured for use as live munitions.

“We’re definitely looking at [direct support fires technology] and how we could be a competitor in that market,” Dave Griser, vice president for Guided Multiple Launch Rocket Systems within Lockheed Martin’s Missiles and Fire Control division, recently told Defense News. “We think we can play there in terms of how we produce, our production and our experience that’s unique to [MLRS family of munitions] and what we do. We think it’s a good fit for us.”

For its part, the Army has been very open about its interest in acquiring smaller artillery rockets to increase the magazine depth of its MLRS and HIMARS launchers. The munitions for those launchers come in standardized ‘pods’ that can hold six 227mm rockets, a single ATACMs, or two PrSMs. MLRSs can be loaded with two of those pods at a time, while HIMARSs can hold one.

Considering just simple dimensions, a pod of the 127mm rockets might be able to hold 15 or more of the smaller rockets (a similar Israeli system holds 18), with range and an explosive effect similar to that of an artillery round, but greater accuracy and an ability to be used with the same launching systems.

The U.S. Army is on the brink of procuring an upgraded tracked and heavily armored M270A2 multiple rocket launcher system, which like its predecessor is based on the M2 Bradley. One of the most recent articles on the M270A2 states:

The M270A2 isn’t just an upgrade—it marks the powerful return of one of the U.S. Army’s most formidable long-range artillery platforms. First introduced during the Cold War, the M270 Multiple Launch Rocket System has been overhauled into a high-precision strike system, now capable of firing guided rockets and future missiles with ranges beyond 300 miles. Built on a tracked chassis, it offers better protection and a higher payload capacity compared to the wheeled HIMARS. The A2 variant features a modernized digital fire control system, enhanced armor, and is designed to support next-generation munitions like the Precision Strike Missile (PrSM).

The analysis of why it is important for a missile launcher firing at targets from 50-300 miles away needs to be heavily armored or tracked, of course, is absent. 

The priority in shoot and scoot non-line of sight (NLOS) military systems is generally speed, not off-road capabilities, but tracked vehicles top out at 45 mph on roads and less off road. If this long range NLOS system is within the 12-24 mile range of enemy artillery or the 2 mile or less range of enemy tanks, someone has made a very serious mistake that heavier armor won't cure. Their tracks also make it easy for surveillance systems to determine where the vehicle was when it fired at the enemy, and where it went afterwards, making it easier to fire back at it if the enemy has those capabilities.  And, the tracks aren't what gives it a higher payload capacity.

There may be a niche where this system is somewhere where it is facing light infantry with small arms but no anti-tank weapons of any kind, or where it needs protection from shrapnel from "successful" active defense system kills of incoming munitions, but this is the exception rather than the norm. 

Its inability to be deployed by C-130 transport plane, as well as the reduced number of systems that can be deployed via a C-17 or a C-5 transport plane, is also definitely a minus relative to the lighter, wheeled, HIMARs system.

Add to this the development of pallet based missiles that can turn military cargo planes into bombers and you have a new era of platform independent missile technology.

The Case For Bills Of Attainder

Every issue has two sides. I find that argument in favor of allowing Bills of Attainder particularly weak. But here it is:

For half a millennium, bills of attainder were an accepted sovereign power, used by British and American governments to defend their people in times of emergency. Throughout the war for independence and its aftermath, the new American states repeatedly attainted loyalists and confiscated their lands, remaking much of the socioeconomic structure of the country. Then, in little over a year and with barely any reasoning, the ratifiers of the 1788 constitution stripped the state and federal governments alike of their power to attaint. Today, attainder bans are remembered as a just and inevitable part of Enlightenment reform. 
But in truth, these bans were anti-republican. Worse, they were a mistake. 
Eighteenth-century bills of attainders were not the arbitrary acts of tyranny that scholars today imagine. They were a narrow emergency power, passed only after debate and examination of evidence, with procedures guaranteeing due process and appeal written into the text of the laws. 
Moreover, although legislators occasionally passed abusive attainders, early Americans proposed reforms that would have prevented abuses without prohibiting attainder outright. In the right circumstances, bills of attainder are a valuable tool of republican government. The history and ideals of the Founding Era provide compelling reasons to embrace bills of attainder in exceptional times.

Middle Ground On Arbitration

One of the biggest problems with arbitration is that there is nothing but the arbitrator's conscience to insure that arbitration decisions conform to the law and the facts, even though they are, in principal, supposed to conform to both. Arbitration clauses with expanded judicial review could address this flaw that discourages parties from utilizing this forum.
This article argues that courts should enforce private contractual agreements for expanded judicial review in arbitration agreements. This article demonstrates that the court decisions enforcing such arbitral contractual provisions are consistent with the FAA’s purpose to ensure enforcement of parties’ arbitral agreements, whatever the form. Furthermore, this article argues that the FAA does not preclude courts from reviewing awards under expanded grounds where parties so agree, because the statutory structure provides default rather than mandatory grounds for award vacatur. Finally, this article concludes that permitting the parties to contract for expanded judicial review serves the public policy favoring arbitration, insofar as it encourages arbitration by giving parties who may be extraordinarily concerned with obtaining the legally correct outcome the ability to contract for expanded judicial review.

Ukraine's Stunning Drone Attack Deep In Russia

After more than a year of planning, Ukraine was able to plant drones on Russian soil, just miles away from military bases. Then in a coordinated operation on Sunday, Ukrainian drones attacked five different regions in Russia. Some were launched from containers attached to semis, their flights captured on videos verified by The New York Times. Plumes of smoke billowed above one base. At another, strategic bombers were hit.

Although the full extent of the damage is unknown, the attack, known as Operation Spider’s Web, showed how Ukraine is adapting and evolving in the face of a larger military with deeper resources. Using drones, Kyiv has been able to push Russia out of much of the Black Sea, limit its gains on the front lines despite Ukraine’s own troop shortages, and hamper Russia’s ability to amass large concentrations of forces for major offensives. . . .

Ukraine said that 117 drones were used in the attacks and that 41 Russian aircraft were destroyed or damaged.

Russian military bloggers played down the damage; the Russian Ministry of Defense said that Ukraine had attacked airfields in the Murmansk, Irkutsk, Ivanovo, Ryazan and Amur regions, and that Moscow had thwarted attacks at three of the bases.

The New York Times verified videos that showed successful strikes at Olenya Air Base in the Murmansk region and Belaya Air Base in the Irkutsk region, and damage to at least five aircraft, four of them strategic bombers.

From the New York Times

If Ukraine's claims are true, and it has a much better track record than Russia for being truthful in its military claims, then Ukraine destroyed roughly a third of the Russian strategic bomber force in a single day, at locations far from the front lines.

This particular assault underlines why supporting Ukraine is beneficial, more generally, to almost everyone outside Russia, because it degrades Russia's military capabilities. And, for the most part, Russia lacks the military industrial base to promptly replace military aircraft and other major military systems that it loses. Ukraine, with strong European backing, doesn't have the same problem.

Every Russian strategic bomber, tank, and artillery piece destroyed is one less that is available to strike any other country with. Every Russian military officer killed reduces the expertise of Russia's military leadership and strangles the pipeline of qualified soldiers who can be promoted to more senior positions.

Losses to Russia's strategic bomber force, in particular, make its nuclear capabilities weaker.

It will be interesting to see, when the Ukraine War is over, how Russia decides to rebuild its military that has already lost somewhere between two-thirds and three-quarters of the major military systems in its Army, has suffered serious losses in its Air Force (although much smaller on a percentage basis), and has even suffered surprising large naval defeats at the hands of an opponent without a navy. Russia has lost more tanks and ground troops than it had in active duty service when the latest round of the war began in February of 2022.

In the bigger picture, this strike also illustrates the principle of modern warfare that there are no firm front lines. Russian artillery crews are trying to avoid that duty because they know they are targets that are being reliably destroyed. Bit by bit, Russia's oil and gas infrastructure is taking a beating from Ukrainian attacks. Ukraine's long range threats are likely to improve with a recently approved infusion of German medium range guided missiles that can strike much further than artillery rounds.

Ukrainians, who were part of the same country as Russia a generation ago, are particularly well suited to infiltrating Russia.

The Last Glacial Maximum


This map represents what North America looked like 77 million years ago compared to its present shape (the black lines mark the outline of the continent as we know it today). At that time, Canada's Atlantic provinces were part of a large landmass known as Appalachia, while the west coast had not yet been integrated into the continent. All this is a consequence of the movement of tectonic plates. During the Cretaceous Period, the two main landmasses were Laramidia and Appalachia, separated by the Western Interior Sea. The existence of these regions has been confirmed by fossil analysis, which shows distinct species in each. The separation of the continents is explained by tectonic activity, and marine sediments confirm the presence of the sea that divided the two landmasses. Geological maps are created by combining fossil remains, analysis of geological formations, and simulations that allow us to reconstruct the tectonic movements and arrangement of the continents at that time.
