Light: x0.5 (Sub-Capital Only)
Note: This means that a light laser cannon/light ion cannon is worth half of one laser/ion cannon, for dropships, gunships, fighters, etc. These are normally pretty useless, good for tagging warheads or soft targets but not much else. Think the pneumatic cannon on a T-16 Skyhopper, or each barrel of a Y-Wing's dual ion turret. Small guns, small effect, generally shorter range.
At this time we're not tackling the light turbolaser issue, though those are very rare in canon and only a couple of ships on Chaos have them at all. They'll continue to be handled case-by-case.
