I do believe this would be a very rewarding addition to the game. Firstly this is how I do it for my eeny weeny tiny KG:
If it was implemented into the game I would add something along the lines of the following:
You get 'killed' in the game you don't actually die, you fall to the ground and cannot move. At that point you press the "MEDIC" button, which flashes you up on the map and a medic-class player has to get to you and heal you. The medic can be killed, in which case he respawns and you remain wounded, still awaiting his ministrations.
However, you can still suicide and respawn, but you lose X number of points, which will impact your chances of achieving the criteria for an award (see where I'm going with this? ).
Obviously your in-game avatar shows the awards on its uniform. Not such a biggie for the allies I guess but the axis should love it. Lol.
