Example: if i was foreseen a double T3485, i would either go for a quick Ostwind into Stug/P4 + Pak + teller (no minefield to avoid forcing a minesweeper) or a more safe aproach, P4 + Stug. On the same way it´s just more safe to get a T34 instead of a T70, i feel that even if the Stug is dirt cheap (230mp + 80fuel) it´s just better to go a P4 or an Ostwind.
