Move-or-Fire Some missile weapons take a long time to load, such as crossbows and handguns. So, a model that is armed with a move-or-fire weapon may not fire his weapon if he has moved at all during that turn. It doesn't matter if the model was forced to move by some compulsory action or by magic. Any movement will prevent the model from shooting, even the simple act of turning round.
Armour Piercing Certain weapons, most notably blackpowder weapons such as handguns, are even better at penetrating armour than their Strength value suggests.
Therefore, the enemy Armour save is reduced by an additional -1. For example, an Armour piercing weapon that has Strength 4 would have a -2 Armour save modifier rather than -1.
