Combat Sensors & Multi-Plex Tracking

[Taz-in-Space]

Combat sensors only work on direct fire weapons. they have no effect on seekers. (Seekers already hit 100% if they reach the target)

AFAIK, Multi-tracking doesn't re-direct seekers after launch. It only allows you to attack multiple targets with one ship.

Fighter missles are considered direct fire weapons so combat support (on the fighter) will add to hit chance.
