That 7.5 Pak at the beginning that was giving you so much trouble should try sneaking up an AT squad and taking it out with the bazooka, works better than snipers or light tanks.
Just beat this level with the offensive doctrine FOW on hardcore. Took a few hours but I don't think this map was as difficult as the first US skirmish.
I think I have to agree, For me personally I think in this map ,it was easier to get the enemies into kill funnels, where in Operation Cobra they had quite a well built up defense. In this map I did enjoy the opportunity to sneak behind enemy lines and destroy the arty at the back
