The Banshee is a fast gunship which is dedicated to harassing enemies which do not have a good anti-air defense set up. "Banshee rush" is a popular Terran harassment strategy in which a Terran player builds one or two Banshees and immediately sneaks them into an enemy's resource line to kill workers. Obviously, this works best against players who haven't built much anti-air. A rushing two-gate Protoss focusing on Zealots, for example, will be a good candidate for Banshee counter-attack.
Banshees can also cloak when the appropriate tech is researched. This ability is very powerful against anyone who has not remembered to make good use of detectors. It also is powerful as support to your ground armies, since enemy anti-air won't be able to attack your Banshees unless they bring a mobile detector (and most players don't).
Obviously, the Banshee's lack of air-to-air weapons makes it very vulnerable to other air units. The Protoss Phoneix is the worst. It receives a bonus to attack against light units and is capable of attacking while on the move. Despite this disadvantage, the Banshee is one of the most effective Terran units for harassment.
