This weapon is only used by the Tusk special unit, Tusk Mortar Bombard, and is attached to the unit's back to allow it to be fired like portable artillery. Can be fired directly in the air for slow, easily avoidable and fairly inaccurate shots at range, or shot directly at players when the Bombard leans forward in an attempt to hit players directly.
Several Tusk units may spawn as these units at once, creating artillery hazards that are hard to spot if players are not paying attention.
