Making bodies stay for some time (yet another thread)

Hello everyone. I've searched the forum and I've found a couple of topics featuring this problem, but neither of them doesn't give a solution. I hate to create another thread, but I'd love to have an exact answer, so here we are. So, let's get straight to the problem, shall we? In the current version I noticed that when a soldier is killed (and I mean killed for good, not wriggling on the ground in pain, that works fine), he falls and disappears immediately. Is there a way of making dead bodies stay at least for some time, a minute, or 30 secs? I'm not asking about them staying till the end of the match/forever, just not vanishing instantly. Maybe it's a bug, or something that can be changed by fiddling with the game options? Thanks in advance.

The "dead" bodies, like after a poor sap gets a sniper bullet through his brain, serves no further purpose to the game.  Injured soldiers are part of the medic system, and thus will remain until they are deleted by the game or are picked up by a medic.

Not sure if it's possible to keep dead bodies, though I've yet to see it.

Not to mention that they will drain performance for basically nil benefit.
