Mortar is a skill that can be given to a lemming in Lemmings 2: The Tribes. A lemming given this skill fires an explosive projectile diagonally upwards. When the projectile lands, it creates a knockback explosion which sends nearby lemmings flying and stuns them. The explosion makes a hole in terrain, but does not affect steel. This skill is entirely similar to the bazooka, except for the angle at which the projectile is launched.
