Indeed those pzIII's provide little help. They got taken out when I played (at hard) even when I flanked the american's; not even being able to destroy them from side/behind. At least, u have to be lucky. Both got taken out 1 shot by them yankee's.
However -> there's a pretty easy strategy i used to combat the americans with relative ease:
trade them PzIII's for 2 nice STUG's, costing the same.
This time the flank attack took the first wave quite easy, from good distance.
Make sure u directly move the stug's to the right position and get ready to flank the first wave. Think about repositioning ahead of time to flank the other assaults and u should be fine, especially with the provided reinforcements.
