OK I just got to September, and I think things went way too fast with the plot at that particular point.
August's main story mission was a real pain in the arse though. I ended up losing about 2 guys (freaking lost Avan on turn 1 because I tried to hide him but that didn't work against Dirk) and the tank doing that mission, although I did manage to hold out for the 8 turns, repeatedly using Nichol as Sniper and the tank in a fire brigade role, switching between camps trying to stop the V2 rush.
I gotta admit, Nichol is pretty good as Sniper...
