The 5B-4S was a model of grenade launcher that was used during the clone wars. It was mainly used by the weapon specialists and bomb experts of SCAR squadron. It fired a 33A model plasma grenade (a design copied from the umbarans) and was devestating to the enemy forces. It could be modified to shoot Droid poppers aswell. A squad of grenadiers would often sweep old ruins or crash sites with 5Bs
