The Banshee is the new stealth assault unit in the Terran fleet, excelling in the one thing it can do - air-to-ground superiority. It has a cloaking ability that drains energy, but renders it invisible to conventional sight – you need a detector unit to see them.
The Banshee can be built from a Starport with the Tech Lab attachment. It is definitely a deadly unit because of its sheer damage and speed, making it an ideal unit in both raiding and full-scale assault.
