Hi, i agree with MrEnzO the revive script must be realistic if you take no lethal like shoot in the head or explosion. In the game you have already some medical stuff : bandage, vishpirin, instadoc, defibrilator , thermal body , better prisoners.
For me the revive must take 1-2min end required many character check, and many medical stuff.
The revive can be a very useful feature mostly in base raiding/defending
