I'm also fighting up that hill on the second mission, I realised early on (after eeer 3 tries) that slow was indeed the way to go. Used to play a lot of CMx1 and it really grips me now how one sloppy waypoint or massing of troops can knock them all out of working order.
The pixeltruppen are, however, fighting just fine with support and a healthy volume of fire and of course early withdrawals when spotting rounds fall. Excellent missions thus far indeed.
