The RD-4 grenade launcher serves as the unique primary weapon for the pilot droid in Star Wars: Battlefront. In Star Wars: Battlefront II, the pilot class was rebranded as the engineer class, and in place of a unique primary faction for each faction's pilot unit, the engineers' primary weapon was standardized to a shotgun. As a result, the radiation launcher was passed onto the MagnaGuards, a special unit, as a secondary weapon.
Like all grenade launchers in the series, the weapon's model is based on the T-21 light repeating blaster.
