I tried playing it 1-2 years ago using the SL-GI rules, and it was totally NOT playtested for those rules. There needed to be a few rules re: when the defending units "woke up".
MY opponent and I both agreed that it would far better in ASL, where there are better rules for searching and moving into enemy-occupied locations.
The main problem was, I think, that the commandos could move through german territory undetected and spend 10-12 turns discovering the enemy's exact location, without any risk of attack. Then they could initiate the attack from whenever and wherever they chose.
I think the commando CG could be very cool, just needs a few simple fixes.
Let us know how you progress with playtesting this one!
