Degtyaryov DT
Pravda High School's Soviet tanks, the T-34/76, T-34-85, IS-2, and KV-2, are all equipped with a Degtyaryov DT as a secondary weapon.
Maxim Machine Gun
A single shot of the command tent shows a "Motor Scout" parked next to it. This 1889 quadricycle carried a .303 Maxim machine gun and shield, 1000 rounds of ammo and 120 miles of fuel, making it the first armored fighting vehicle. It was designed and built by British manufacturer Frederick Reginald Simms, but never entered service: it was, however, the ancestor of wheeled armored cars.
