Gunnery

Fire ship and vehicle weapons.

Gunnery is the art of hitting things that are very far away and moving very fast. It covers turret-mounted lasers, railgun batteries, missile launchers, point-defence clusters, and vehicle-mounted weapons. Unlike personal-scale combat, ship weapons do NOT use BAB -- the gunnery resolution is entirely skill-driven: d20 + Gunnery ranks + DEX mod >= 10 + target Evasion. A skilled gunner is the difference between a kill and a miss at relativistic ranges. In the verse, gunners are the quiet killers of fleet engagements; the Legion trains dedicated fire-control specialists, and every pirate crew needs someone who can thread a missile through point-defence.

Notes

Special: Ship combat is NOT BAB-driven. Resolution uses d20 + Gunnery ranks + DEX mod vs. 10 + target Evasion. The Gunner feat (4 ranks) grants +1 and halves called-shot penalties.
