M22 Arbiter

The M22 Arbiter is a Confederate main battle tank. The M22 is heavily armed and armored, featuring modular armor plating that swaps out easily in minutes and a magnetically-assisted 120mm smoothbore tank gun as its primary weapon. The M22 is powered by an electric-hybrid Honeywell AGT1700 engine and driven by for separate articulated treads for better mobility in difficult terrain.

M22 Armament
The M22 Arbiter features the following weapons:

M212 120mm Mag-Gun
The M212 120mm "Mag-Gun" is a magnetically-assisted 120mm smoothbore tank gun that fires rounds at speeds half-again better than a similarly-sized conventional tank gun. This greatly increases both effective range and penetrating power, allowing the M22 to engage targets well before the Arbiter comes in range of enemy guns.

M22A2 Gorgon Heavy Machine Gun
The M22A2 Gorgon is a heavy machine gun chambered in .50 BMG. It is the modern evolution of the venerable M2 Browning heavy machine gun that still sees use in some planetary defense forces over two hundred years after its introduction. The first Gorgon is mounted in a remote turret controlled by the tank commander, while the second is coaxially mounted and controlled by the gunner.

30mm Grendel Rotary Autocannon
The 30mm Grendel is mounted to a swing-arm attached to the loader's hatch and can be retracted into the tank to protect it from damage. The Arbiter's Grendel serves as the tank's primary anti-aircraft weapon, but serves equally well as an anti-personnel and light armor weapon.
