The AT-1 is the very first Soviet TD available to the player.

It has extremely weak armour, even for its tier and can be

penetrated by most of the tanks it will come up against;

however, its gun is one of the best for tier 2, and with its

high RoF and Damage not many tanks are in your sights

for long before they burst into flames. this will help you to

cope with the higher tier Russian TD's as they also have paper

armour and big guns. Such as the Soviet teir 8 TD: the ISU-152, with

its amazing 152mm BL-10 cannon but weak armour all round.
