The T-26 was a Russian light tank based on the British Vickers Six-Ton tank. The T-26 Model 1931, a twin turret machinegun tank, went in service in 1931 and was used mostly during the outbreak of the war. The Polish 7TPdw is a nice example of a twin turret tank. In 1933, the Soviets unveiled the T-26 Model 1933. The Model 1933, with a new single cylindrical turret carrying one 45 mm cannon and one 7.62 mm machine gun, would become the most common T-26 variant. The 45 mm 20K tank gun was based on the Soviet 45 mm anti-tank gun 19K (model 1932). The T-26 could carry up to three secondary DT 7.62 mm machine guns in coaxial, rear, and anti-aircraft mounts. This increased firepower was intended to aid crews in defeating dedicated anti-tank teams, as the original machine gun armament had been found insufficient. The turret rear ball mounting for the additional DT tank machine gun was installed on the T-26 tanks from the end of 1935 until 1939. The T-26 Model 1933 carried 122 rounds of 45 mm ammunition, firing armour-piercing 45 mm rounds with a muzzle velocity of 820 m/s (2,700 ft/s), or lower-velocity high-explosive rounds. Tanks intended for company commanders were equipped with a radio set and a hand-rail radio antenna on the turret (called radio tanks). Later the hand-rail antenna was replaced with a buggy-whip antenna, because the Spanish Civil War and Battle of Lake Khasan demonstrated that the hand-rail antenna unmasked commander tanks for enemy fire.
The T-26 flamethrower was a series of flamethrower tanks based on the light T-26 chassis by mounting a KS-24 and KS-25 flamethrouwers in the main turret. Some twin-turret vehicles were also used but soon only single turrets were used. Ingame we have the model with the KS-25 flamethrouwer which can have a range of 50 metres.
