Blitzkrieg Commander Germans vs US

OK we experimented last night with an attacker/defender game. Scenario 2 in the book, 2000 points of late war Germans against 3000 points of (very) late war US (including M26 tanks and naval gunfire support).
In the game the US forces have to capture an objective within 8 turns whilst the defenders are dug-in and invisible until they either open fire or the attackers are within 20cm of them.
Sorry the pictures are not up to the usual standard, I used my phone camera for these.

The game was won by the US forces on turn 5, simply by the Germans being slaughtered. IMHO a better defence would be groups of units in strongpoints rather than strung out in a line. Also better to have German infantry well in front, supported behind by longer range weapons.
The dug in units were hard to hit (needing 6's) but because we used the optional 'keep the wounds on' rule a unit could be hit over a number of turns and gradually 'killed', it would have given the defenders a slight advantage if excess wounds had been removed. No problem with length of game, it was over by 9pm (started at 7.30pm).
15mm BKC is obviously a hit at CACK probably because of the visual appeal of the models but it also is a very balanced game. We had been playing with 6mm but I think that players will be moving up to 15mm and we are buying some more terrain (including bunkers) to give a few more options.
