The T-26 tank is the first Soviet mass-produced infantry support tank. It was armed with DT machine guns mounted in two rotating turrets. Some tanks had a 37mm Hotchkiss gun installed in the right turret. A total of 11,000 T-26 tanks were produced.

The German motorcycle Zündapp K800 is considered one of the most beautiful motorcycles in history. It was produced from 1933 to 1938, with a total of 7,569 units made. The Zündapp K 800 was equipped with a 4-cylinder, boxer engine with a power output of 20 hp. The military version of the motorcycle was especially favored by soldiers, but this model often had issues with oil-fouled spark plugs in the rear cylinders due to insufficient cooling. During World War II, the Wehrmacht had about 550 units of the military version of this motorcycle in service.

The production of heavy KV tanks armed with a 76-mm gun began at the Leningrad Kirov Plant (LKZ) in February 1940. This tank embodied the most advanced ideas of its time: individual torsion bar suspension, reliable shell-proof armor, a diesel engine, and a single powerful universal gun that allowed it to fire both at enemy tanks,

as well as at his field fortifications, artillery, and manpower. By the beginning of the Great Patriotic War, LKZ had built 386 KVs.

The Soviet main battle tank T-62 was the world’s first mass-produced tank with a smoothbore gun, and had the weight of a medium tank while offering a high level of armor protection. The tank, which was a development of the T-55 model, was equipped with a 115-millimeter U-5TS gun. From 1962 to 1975, more than 20,000 units were produced in the USSR.
