"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') is a modified version of the Monitor, replacing its main gun and rearranging the layout 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 3,000 metres. The vehicle has had its turret fixed and constructed as part of the superstructure, to provide more room and stability for the mortar.

The vehicle has been modified for close urban fighting, with the whole tank being heavily uparmoured. A second point defence laser is installed, just covering enough of the rear to stop missiles aimed at the vulnerable engine. The gas turbine and diesel engine have been replaced by a single diesel engine, made solely for propelling the tank at a good speed, helping it conserve fuel while remaining agile.

The weapon fires 350mm rocket powered mortars. Four varieties exist: first is the 'Smasher' HE shell, famed for its use on infantry targets. Next is the 'Crasher' shaped charge round, which is capable of penetrating four meters of concrete. There is also the 'Crusher' round, which has a heavy tungsten rod useful for penetrating targets. This round is covered with microveins and a hollow warhead, both of which are filled with High-Explosives, allowing the Crusher to kill occupants behind up to 2.5 metres of reinforced concrete. The last is the 'Masher', which had the same tungsten penetrating rod filled with microveins of explosives, but benefited from an 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 their 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 is 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 two meters deep crater"

"We had a building fulla Remnants 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."
