Just got an idea - what about sectors of fire? Say that you'd be able to set the vehicle at the end of the turn to face the selected sector and would OPfire just targets coming into it uless target's say under 10 hexes?
OK, can be achieved by limiting OP range and firing controlled shots just in the player turn. Would be harder to implement than it's woth it. Just been thinking loudly and it's late and I haven't posted here for a while anything so I'd post it anyway
