The M909 Mamba is the successor of the versatile M808B 'Scorpion' Main Battle Tank. While the Mamba has been up-armored from its preceding model, it is even faster than the Scorpion and even more capable against a number of enemies. Along with the Scorpion's M512 Smooth Bore High Velocity Cannon, the Mamba can be equipped with a multitude of coaxial weapons, most commonly a 30mm Autocannon and an M751C HMG. Other weapons include an M480 Automatic Grenade Launcher or even an M7 Titan Laser. The M909B variant replaces the coaxial M751C for a pintle-mounted M751B variant, giving the main armament an extra slot for more firepower.
