Nagl and Rice, writing in the Small Wars Journal argue that making cluster bombs available to Ukraine starting in May 2024 has greatly increased Russian casualties:
The success of cluster munitions is seen most dramatically in the Russian casualty count increases after all the significant milestones above. Russian casualties have increased to over 35,000 casualties per month starting in May 2024 and have had over 150,000 dead or wounded Russians in the past five months alone[.]
