The Espo Grenade Launcher was a grenade mortar in use by the Espo and other organizations. It was popular for its high ammo capacity, long range, and ability to fire any type of grenade available. Heavy Weapons Specialists of the Alliance Special Forces also made great use out of the launcher.

While the mortar came equipped with a repulsorlift generator, the unit was only powerful enough to make the mortar easier to carry.
