The XM-1 (GM) is one of two main prototypes of the M1 Abrams, sharing many visual and functional similarities.

The XM-1 has a versatile selection of ammunition for its 105 mm cannon, including APFSDS, HEAT-FS, HESH, and smoke rounds. In addition, a thermal sight and laser rangefinder will help quickly identify and accurately hit enemies at range. Its mobility is where it truly excels however, with a 1,521 HP engine easily pushing it to speeds over 80 km/h, with great acceleration and maneuverability. It also features hydropneumatic suspension control, allowing you to raise and lower the hull to aim over terrain or take cover more effectively.

The mobility and firepower of the XM-1 (GM) make it very suitable for aggressive rushes or swift flanking maneuvers. The XM-1 is at its best when utilizing its speed to reach strong positions, making it a highly versatile MBT.
