This is Guards Attack from FKaC (numbered 108 or A35, Brits vs. Germans) not Guards Counterattack. I'd take the Brits.
I can average at least 5 files/week, sometimes more. I'm fairly new and still getting some rules straight (i.e. you might need to correct me on occasion), but I'll give you a decent game.
Would prefer to play it for the WARS ladder and list it on WeASL, but neither is essential.
