In Arma 2 OA, soldiers had the ability to carry/drag their wounded buddies. The only way this is possible in Arma 3 is by scripting, which is quite jerky and looks bad. I propose that when soldiers are severely wounded and are unconscious / cannot walk (stepped on a land mine, knocked out, etc.), other soldiers, including the enemy, should be able to move them to cover and heal them / bring them to base and interrogate them and all that fun stuff. Some of the uniforms have carry handles, so the animation could be accomplished by having the person crouch down, reach (like explosive placement anim.), and then could only walk back or could press "X" to carry them on their back. To make the body dragging more natural, the wounded soldier would just rag doll with an attach point on the "carrier" hand. The body would stop rag dolling when put on the carrier's back.
