The GHUJ-6 Detpack launcher was a sophisticated Imperial weapon that amounted to an advanced grenade launcher, and was used mainly by FIST troops. It could fire a variety of ordnance, from EMP grenades to inciendary explosives to remote charges, and was equipped with an intelligent voice-recognition programme that allowed a user to change weapon settings simply by speaking. It proved highly effective against enemy armor, but soon fell into widespread rebel use after a weapons raid, and so was phased out after Endor.
