The Protoss Carrier Unit is built from the Stargate. The unit does not have any weapon batteries, however, it can deploy interceptor flights on the enemy. This is a particularly effective strategy against opponents with a large air fleet because this unit does excellent damage in air to air combat.

Much like the mothership, the Carrier is classified as a Capital Ship. The Carrier is enabled with weapons that allow it to strafe slower ground targets with plasma charges. This makes the Carrier very effective against both ground and air units.

My favorite part about the Carrier is that the interceptors are automatically manufactured and serviced inside the bays of the carrier. This makes the Carriers excellent for hit and run attacks, or a micro strategy that involves sweeping them through the battlefield.
