I highly advise you to check the original poster's comment. 2 T34-76s shouldn't lose to an OKW P4 in any situation, even in a frontal max range stationary fight.
Of course we all know that the OKW P4 is individually superior. He was talking about 2 tanks vs 1 and still losing the engagement.
Cost and role-wise, they shouldn't.
But that engagement is decided by RNG that does not favor T34, especially vs OKW P4 at max range.
