Playing Dead

As it's a realistic fps game, you could allow a player to play dead when hit because the reaction of a man when hit is the only clue in comnbat.
As a footnote, playing dead is not allowed in the Geneva Convention and a soldier playing dead can be shot. Apparently it's cheating.
The rules of war must be the most farcical idea ever.

I've seen this implemented in a couple of games before, and its always felt like a poor mechanic - the player playing dead never really gains anything from it. Something to think about though.
