Missiles
Missiles are an oddball here (like in many things)
Large size, high dps, short range, slow: Torpedos (Siege launchers) Large size, low dps, high range, faster: Cruise
Med size, high dps, short range, fast: HAMs (Heavy Assault) Med size, lower dps, high range, slower: HMLs (Heavy launcher) Med size, low dps, shorter range, fast: Standard (Assault launcher)
Small size, high dps (yeah lol), short range, fast: Rockets Small size, lower dps, more range, slower: Standard (Standard launcher)
Assault launcher uses the same small Standard ammo but on a higher dps, higher fittings launcher. Fittings vary around the lineup, with HAMs having such absurd requeriments thats almost impossible to properly fit them in most things besides a Drake (don't even try on a Nighthawk for example) Also, short range versions are UNGUIDED, not affected by the precision skill. They also have slower explosion velocity than the guided ones (the long range version).
Rockets sucks all around.
