Soviet Light Tank T-26S

T-26 was the main tank of the Red Army during the 30's years. It earned the enemy's respect during the Spanish Civil war and Soviet-Japanese conflict in Mongolia. The production of the light tank T-26 began in the autumn of 1931. T-26 had better armour protection than it's English analogue (as do say Soviet books, the truth is that the T-26 was the copy of the English "Vickers 6-ton") and the Soviet engine. The first variant of T-26 had two turrets with one machinegun in each. These tanks were producted till the august of 1933, when the 45mm tank gun was invented. The tank of the year 1933 had one cylindric turret with the gun and machinegun in it. The mass and the height of the vehicle lightly changed, other characteristics did not change. From the year 1937 they had conical turrets, it helped to increase the rifle-fire protection. Many tanks had the machinegun in the back of the turret and the anti-aircraft machinegun at the top. Also they received the first instruments for better targetting. The last modification of T-26, produced from the February of 1939, had sloped front armour. During the Soviet-Finnish conflict, it had also front armour increased up to 60mm. Sometimes these tanks were called T-26S (by the western authors). The construction of T-26 was simple and it was also easy to drive. Anyway, it was not fast and its technical reliability was low. The main task of the T-26 was the infantry support.

Soviet Light Flame Tank OT-130

"In the end of the August 1939 Soviet-Mongolian forces began the offensive against the japanese militarists who invaded the Mongolian People Republic in the region of Halhin-Gol river. Japanese had occupied this region for a quite long time and made the perfect defensive positions. Burrowed into the ground and fiercely fighting Japanese soldiers were nearly impossible to push out from each trench and bunker. It was a difficult task, which cost a lot of time and lifes. Then several light T-26 tanks were thrown into the most hardly defended parts of the defense. They came under the gun and rifle fire without any reaction. And only when they came to the very firespitting holes of bunkers, the long streams of flame with the black smoke has left the tank turrets. Burning liquid flew into the bunkers, leaving no place uncovered. The enemy's fire was stopped, survived Japanese soldiers retreated in terror. Our warriors took the enemy positions without opening fire." - Action of flamethrower tanks, 6th tank brigade in Mongolia.
