A Panther can usually go chasing Allied vehicles to finish them off. Because it is not up against Schrecks, and unless it grossly overstretches, even eating an AT grenade to the face will see it reverse and live since it reliably bounces most frontal shots. Whereas against OKW, if you dare step with your armour one meter in front of your infantry screen, it's Schreck party time baby
!
I also like how people suggest the use of BAR blob against OKW blob. First of all it does not work (add a squad of Obers or two, an MG34, a PzII, or a Stuka to the mix), and second of all even if it did, if I wanted to play Blob of Heroes I would have purchased that.
I'm not saying you defeat OKW blob with that, but you can resist to it a period of time and maybe win the game.
Why should the US forces be the ones RESISTING and somehow hoping to win while doing so? Why are there no threads on the forums about how OKW must RESIST the US armoured attacks and somehow hope to win while doing so?
Furthermore, how does one "win" exactly in this manner? This is not Age of Empires, there is no "Wonder" building you can build to win while turtling. You have to fight OKW on the field to control VPs.
