The MobileMortar-3 was an artillery platform which combined the MM-s3 grenade launcher and WW-676 repulsorlift sled to create a mobile fire-support weapon. MobileMortar-3s were used by both the Galactic Empire and the Alliance to Restore the Republic, as well as the later New Republic and planetary defense forces. These platforms were typically issued as support weapons for army platoons, or operated as four-vehicle light mechanized infantry units.
