I can confirm that. I have heard the same logic from War Veterans (Iran/Iraq). During the war Iran had 2 kinds of rifles AK-47 for IRGC and HK G-3 for Army. G-3 was notorious for its ability to kill in 1 shot in torso which removed one enemy soldier from battlefield while AK-47 only caused injuries which in turn made a bigger tax on enemy manpower and logistics during an operation.
