Cover for hiding but not for bullet protection

Yet SP is clear, but I can tell it's impressive when killing of Allied Soldiers in Call of Duty (it's an SP Mod allowing to play as a German), when the insane amount of dead bodies is lying around.
So if we got corpses "forever" then the weaponry they dropped should be lying there "forever" also. So if no one picks the fallen's rifle, SMG, grenades, etc. up it should stay there.
Clientsided ragdoll. I only know that problem from CoD 5 in a slightly different way. There are localized versions and f.ex. the German version has no body destruction enabled. So you can't "hide" behind limbs, you see on your screen, cause the enemy doesn't see them, cause in his version they are not there. Sometimes heavily annoying.
