Info:
Armoury / Heavy Weapons:
This is the ability to build, modify, and repair a specific class of weapons or armor. (It does not include skill at design; for that, see Engineer)
A successful roll lets you find a problem, if it isn’t obvious; a second roll lets you repair it. Time required is up to the GM. You must specialize in one field:
Heavy Weapons:
All weapons used
with the Artillery and Gunner skills.
