Would it be at all possible for the Soviet and Ostheer infantry to have some sort of ability that lets them collect a small amount of munitions from each enemy unit they kill?
Obviously it wouldn't be a lot, say, 1-5 munitions for killing an enemy infantry squad/weapon team?
I'm suggesting this because there was a lot of examples of Soviets and Germans using captured weapons, munitions, supplies, even German troops stealing Russian boots.
This could be representative of the real life captured equipment usage, and a possible stand in for the inability to re crew enemy weapons.
It's just a thought, I'd like to see how others view it.
