The B2 battle droid dispenser, which is also referred to as the super battle droid dispenser, functioned as a cylindrical droid dispenser. During the Clone Wars, it was employed by the Confederacy of Independent Systems in their conflict against the Galactic Republic. This mechanism consistently provided B2 super battle droids from four substantial hatches positioned at equal intervals. While resistant to blaster fire, the device could be eliminated through the use of a detonation pack. Featuring a propulsion capability, these dispensers could be launched onto ships by Lucrehulk-class droid control ships. Delta Squad, an elite squad of clone commandos serving the Republic, encountered these units across various operations, including the First Battle of Geonosis, the Attack on the Prosecutor, and the Mission to Kashyyyk. During the assault on the Prosecutor, an acclamator-class assault ship, Trandoshan slavers under the Confederacy utilized the droid dispensers in an attempt to eliminate Delta Squad.
The B2 battle droid dispensers made their debut in the video game Star Wars: Republic Commando, which was released in 2005 and developed by LucasArts. Prior to the game's launch, the device received mention on LucasArts.com's webpage dedicated to Star Wars: Republic Commando. Within the game's mechanics, droid dispensers continuously deploy droids until the dispenser itself is destroyed, although this is likely a gameplay element.
