Calibre (X)

Weapon Special Rule
Weapons with the Calibre rule will be followed by either L, M, H, S which refers to the tonnage value they have been designed to target.

When these weapons are fired at targets with the same tonnnage value as their weapon, reduce the lock value on their profile by 1. If the weapon has more than 1 tonnage value listed, then reduce the Lock when shooting at any of the listed tonnage value. In addition, weapons with the Calibre H and/or S rule inflict Critical Hits on rolls exceeding their Lock value by ONE rather than the usual two (against targets of any Tonnage value).
