Weapon, Rate of Fire

This is the maximum number of shots that may be taken by this weapon per action. Unless a weapon says otherwise, the user can fire up to the weapon's Rate of Fire (rather than its full Rate of Fire). If a single shot is taken, it uses a single round of ammunition and does not incur any recoil penalties. Two or more shots with such weapons always incurs the -2 autofire penalty.
