Missle Turrets are relatively inexpensive structures that will automatically target and fire upon incoming enemy aircraft. They also serve as sentry stations equipped with powerful sensors capable of detecting cloaked vessels.

Turrets on the other hand, are used exclusively for defense-but not only for their ability to fire on air units. Turrets are also detector units, which means they can spot cloaked enemies as they spproach. Often this skill is the Turret's most valuable asset, because without the detecting Terret, a base that's being attacked by an invisible attacker will eventually become rubble. Place Turrets around bases is always a safe bet, both against air attacks and clocked invaders as well.
