Ah ok, that one. I didn't use that many tanks there. I mostly spammed my western hedgerows with Milan teams and good AA. Not so much for choppers, but to stun the armor when they come in, giving my Milan teams good locks.
I used the Chinooks behind them for supply, feeding off the western, French?, forward base. I barely made it in the end though, I was pretty much down to the last bullet, yelling at the 'Signing imminent' newsflashes.
