Tank used Object 252U and Wz-1115A
First of all, I hate block mission they forces you to play wrong and not in the best way for the team. However its a mission and you have to do it. 5 games to block 40 shoots. I thought that I was going to have probem with this mission but I actually got very lucky. Got Mines and went hull down in the middle. A Caernavon with stock gun was trying to penn me. After 31 bounces he gave up. I didnt fire back at him during that time, was fireing at other tanks.
Best of luck to you and I hope you are as lucky as I was
