Recovery and repair to be sure is outside the scope of our grand game.
I know and have seen in peacetime Exercises vehicles recovered in what would be normally under fire in a real battle but only because they are so expensive.
In combat under fire or the threat of fire even a flat tire, can be an immobilization kill until the threat is removed. I've driven a vehicle with a flat out of an area under fire, but I'd damned if I was going to risk lives to fix it with incoming rounds all over our LOC. (I'm sure that Recce 4x4 would have had 1 point of damage since we could get it moving, not to mention some suppression applied to the crew, my partner and I
!
) IMHO
