This system is simple: Firer rolls their two dice, one for weapon size, the
other for weapon effectiveness. Target rolls their two dice, one for armour
level, the other for armour effectiveness. If the Target rolls both dice
higher than firer, the target is undamaged. If only one of the dice rolls
higher than the firer, vehicles are damaged but infantry are undamaged. If no
dice rolls higher than the firer, the vehicle or infantry is destroyed.

For a damaged vehicle, assume it has standard damaged result or roll on this
damage table:

1D10 Special
----    -------
1       Escape! - Vehicle is undamaged
2       SD              - Target Systems Down, vehicle can't fire.
3 SD 4 SD 5 SD
6       Mobility        - Vehicle can't move.
7 Mobility 8 Mobility
9       Boom!           - Vehicle destroyed.
10 Boom!
