Would this not be a nice addition idea? a Stretcher to carry wounded mates out of harms way. Seems like a drag yes (pun intended), but It would make for nice medic play in many types of play situations such as RP or private servers type game play. Imagine being passed out for some time and your friends could get you away from danger (or a nice player carry player animation could work as well)
If need to you could lug your own shit around, but slower to give a realistic feel.
