I like the way it is
I think one reason it's the way it is, exp. with large Atry crews,
Is that some gamey guys would exploit the game after all rounds have been fired off,they would use them as a fighting force,which is not at all right,
they should stay with thier guns not abandon them or let them fall into enemy hands.
As for armour crews,,,if they survive thier mount blown up or have abandon they would certainly not be wanting a fight, more like wanting a medic.
