"Don't think your bunkers will keep you safe. This thing penetrates four meters of reinforced concrete."
―Lieutenant Lucien Vall

The M813 Goanna (also know as the 'Anna' the 'Sturm' or 'The Bunker Buster')as a modified version of the Monitor, its main gun and layout rearranged to incorporate a 350mm Mortar.

It started life as a refitted version of the Monitor that had suffered damage to the main gun. Its armament was originally thought to be a joke by HIGHCOM until it penetrated a bunker at 3000m. The vehicle has had its turret fixed and constructed as part of the supstructure, to provide more room and stability for the mortar.

The vehicle has been modified for close urban fighting, with the who tank being heavily uparmoured and the addition of a second point defence laser, just covering the rear from missiles aimed at the vulnerable engine. The gas turbine and diesel engine have been replaced by one single diesel engine, made soley for proppelling the tank at a good speed and helping it conserve fuel and remain agile.

The weapon fires 350mm rocket powered mortars. Four varieties exist, the 'Smasher' HE shell, famed for its use on infantry targets, the 'Crasher' shaped charge round, capable of penetrating four meters of concrete, the 'Crusher' round with a heavy tungsten penetrating rod for penetrating targets, filled with microveins filled with HE and a hollow warehead full of it as well, capable of penetrating 2.5 meters of reicnforced concrete and killing the occupants and the 'Masher' which had the same tungsten penetrating rod filled with microveins of explosives but a incendiary charge.

UNSC remarks

"During a counter offensive on Holy Watcher one of these things blew a hole through the exterior compound's walls, then the interior compound and when the Remnant sealed up thier bunker it gave us a 'key'. The Brutes still looked confused when we ran through the dust and rubble on the other side of the bunker."

"Some say the demo mortar on the AVE its brutal on infantry but we hit a convoy of Shadows with this thing. Three of them in close formation, choked full of infantry. We just estimated how many there were, we found shit all traces of them in the 2 meters deep crater"

"We had a building fulla Remants firing off heavy weapons at us, it woulda been funny to see the look on those Charlie Foxtrots faces. Fuel Rod Cannon rounds just bounced off our front plate, the few that exploded did jack shit. We gutted the whole front of the building in one shot in retaliation."
