The Mortar is a muzzle-loaded indirect-fire projectile weapon whose origins go back to well before any other weapons currently in use by the Imperium of Man. The Mortar has the ability to bombard enemy positions from behind cover. As such, the vulnerability of the Imperial Guardsmen firing the weapon is reduced and they survive longer. Although with indirect fire abilities the mortar is not exceptionally strong against more powerful troops - and certainly not against tanks. The Mortar is primarily used against enemy infantry, other mortars, such as the Quad Launcher and the Heavy Mortar, are used for the larger targets.
