Medusa

One of the heavy artillery units available to the Legiones Astartes is the Medusa, which carries a short ranged but extremely powerful siege mortar capable of breaching all but the thickest walls. When a breach has been secured, the Medusa will then rumble forwards to support the assault, levelling buildings with a single shell.
