O-391 Self-Propelled Gun

The Orcish 200mm O-391 is a highly effective self-propelled gun (SPG). In fact, it became the most important of United Orcs SPGs in the First Bacterian War.

The howitzer itself is mounted on a tracked armored chassis powered by a turbocharged petrochemical engine. With a total mass of about 25 tons, the weapon is capable of a top speed of 55 km/h. The enclosed turret is capable of 360 degree traverse, and protects the crew against chemical and light conventional weapons, and even against some nuclear weapon effects.

The 200mm howitzer uses separate-loading rounds, and can fire HE, chemical and canister shells. The O-391 is also capable of firing special-mission shells, such as the PR-901 "Fleshburner" plasma round, and even tactical nuclear rounds. The weapon can fire a 50kg shell to a maximum range of 25 kilometers.
