With a chassis akin to the E-5 blaster rifle used notably by the Trade Federation's B1 battle droids, the RLR was primarily an extremely devastating antipersonnel weapon, but was also effective against armored vehicles. The weapon held a clip of six rocket-propelled grenades and could fire them rapidly when the weapon was not locked on a target. When locked, the firing rate of the weapon was much slower, but allowed more kill power against small targets. These rockets, with a sluggish fly-time, were most effective when they could catch clone troopers off-guard or unprepared.
