Explosions and Nuclear Warheads

When an explosion occurs, we can generally distinguish three zones:

zone DH for Direct Hit. This is the spot where the bomb falls.
zone KZ for killing zone. This is the area where the effect of the bomb cause the most casualties.
zone CZ for casualty zone. It is the zone of the explosion blow where all the fall outs of the explosion are dragged. 

Several types of explosive heads coded AA (used in rocket launchers) exist up to J (for mini offensive grenades). Each of those are defined by the power of fire and its power of penetration.

NB: May I remind you these are the minimum targets to be achieved on 1d10 to penetrate shields and  that A means automatic !

For nuclear warheads (great eh!) the same principle applies except that we add up a fourth zone called GZ for Group Zero, no need to translate that.

GZ is situated closed to DH and indicates you an ideal spot for roller blades on a vitrified surface.
