What about adding a sound of heavy breathing and hurting, like the sounds you get once you see black and white before youre completely wounded and incapacitated. So that nearby players will know whether its a wounded soldier or dead soldier, for both factions of the map ofcourse. Im not gonna say its simple, cus nothing really is with this engine, but it seems alot more simple than the recent suggestions.
Its realistic too. I know it could be useful if you were shot down in the jungle closequarter, and hostiles walk over you with your body hidden in the bushes. Its useful to be quiet sometimes if you wait for evac(the medic bag). But im sure in most cases, its almost impossible to stay quiet once youre wounded enough not to move at all.
If you want to make it complicated, you could make players be able to use fatigue to hold back the sound, if you want to make it complicated
