A concussion grenade mortar mounted on a Mobile Defense Unit The concussion grenade mortar weapon system was equipped on Imperial Mobile Defense Units. Additionally, the Hutt Cartel employed these mortars as automated defensive turrets, notably on planets such as Nal Hutta. It launched a salvo of eight grenades toward an opposing target, continuing until either the mortar or its designated target was eliminated. While the grenades lacked precision, they inflicted area-of-effect damage to hostile units in the vicinity.
