On Track to the IS-4 - Featuring the Churchill III

The IS-4 is back On Track! If you want to be feared and respected at tier X, climb the Soviet heavy tree and pick up this versatile brawler! The IS-4 excels at short to mid-range combat with its tough side and turret armor. Pick the right spot to lead a breakthrough, stay away from artillery and angle your armor -- you're sure to strike fear in the hearts of the enemy team as you lead your comrades to victory! 

For the duration of this On Track, enjoy discounts on tanks leading up to the IS-4 as well as missions designed to accelerate your progress towards this formidable heavy tank, and potentially earn the tough, fast-firing Churchill III heavy tank!
