Charlemagne M9

The Atlantis Ground Tank Carolus Magnus Model 9, commonly known as the Charlemagne M9, is the main battle tank of the Terran Army. It is a ground tank, meaning it does not utilise anti-gravity levitation technology. 
It was developed from 2703 to 2718 and production began in 2720, replacing the post-Great War Model 8. Like all Terran ground tanks since the Unification, it is designed and produced by the Atlantis Corporation and is named after Charlemagne. 
The tank's principal improvement over the M8 is the integration of a light Clarktech-made bi-shield. This effectively makes it invulnerable to energy-based infantry weapons and low-velocity kinetic weapons. It uses the same turret and main gun as the M8, but has an improved chassis. It is powered by an MRGS chemical-engine. The tank is designed for a crew of four, which can be in the tank or remotely control it. 
Along with the Alexander M6, the Terran levitation tank, the Charlemagne represents the bulk of the Terran Army's armoured vehicles meant for frontline combat. Over 2000 units have been produced and another 30 000 are scheduled for 2750.
