Seems to work somewhat all the way wave 101, but then you are pretty much screwed, one shot from enemy tank wiped out basicly all my inf and tanks aren't much good as they don't seem to fire enemy tank with their main gun like never!
Why the hell tanks dont shoot enemy panzers?! I had 5, yes a five tanks in a row with infantry support in bottom of my map when german panzer appeared, nothing, not a single shot! panzer took eventually out 3 of my tanks and then disappeared without a scratch!
