The B2-HA super battle droid represented a heavily armed modification of the B2-series super battle droid. It was deployed by the Confederacy of Independent Systems throughout the Clone Wars, including its participation in the First Battle of Geonosis. These droids possessed a built-in rocket launcher capable of launching homing rockets. Their role often involved leading other droids, for example, the B1-series battle droids. As an example, a B2-HA assigned to patrol leadership was a member of the Hissrich droid unit commanded by the droid mercenary AD-W4. In one instance, a B2-HA commanded B1 battle droids on the planet Rodia.
During the time of the Imperial Era, the Bedlam Raiders reprogrammed a significant number of B2-HAs on the world of Koboh. A modified unit within their ranks was known as "Beetu Deetu."
The initial appearance of the B2-HA super battle droid occurred in "Ambush," which was the debut episode of the animated series Star Wars: The Clone Wars. This episode was initially broadcast on October 3, 2008. The droid's formal identification took place later, within the 2016 children's activity kit titled Star Wars Builders: Droids. This kit was authored by Cole Horton as part of the Star Wars Builders series, published by Silver Dolphin Books.
