Hardest tank to kill?

[stugumby]

Have tried and tried on a simple column of 4 tanks going along a runway and i cant kill these tanks with any of the 30/37 mm guns on the hs 129 or ju87. Changed tanks to t34 or sherman and no problem. I know kv had very thick armor but from in a shallow dive etc cant kill it by aiming at back deck behind turret or from the flank.
