Mortar (weapon)
From Wikinfo
A mortar is a military weapon consisting of a tube into which is dropped a mortar shell, which is then fired in a high ballistic trajectory. Modern mortars consists of a simple lightweight tube; however, early mortars were very short, very thick cannons, and some required transport on railroad cars.
Modern mortars are often portable by infantry and can be used as a small-scale substitute for artillery.
