Tank used ISU-152
Another mission that forces you to play for just the mission and not the team. Tried alot of tanks here the main problem is that you have to make it 3 times in a row. You are almost forced into fireing HE shells and what this do is as soon as the enemy notice that they rush you and kill you, I know I do the same thing. I mostly tried T10 which was the problem for me, most people with T10 tanks know how to play so you get rushed if you fire HE. Got frustrated and bought the ISU-152 with the derp gun and crossed my fingers and hoped for top tier battles with more lower skilled players. Finally I made it.
Best of luck to you, think you will need it
