As of Dec. 11, the latest date for which the Army had figures, 3,954 IRR soldiers had reported for duty. In addition, more than 1,600 had been excused from duty and 463 had been sent orders but not yet reported. Of those 463, the Army has been unable to locate 383. The other 80 are the ones who now face discharge.
The Army has considered criminal absent without leave charges, bad conduct discharges and dishonorable discharges, but settled on a more lenient scheme where soldiers who have been located but failed to report to duty will be discharged from service (i.e. kicked out of the Army Reserve) and face at worst an "other than honorable" discharge (which voids many veteran's benefits), although some may receive honorable or general discharges which allow the individual to receive veteran's benefits. For someone not wanting to throw their life and career away by going to Iraq, this is a pretty good deal.
