Strategy - Advancing against very strong AT Guns

[campsawyer]

Ok, I think my picture was too big.

The Germans are just piled up in the north. They are actually off map at the moment.

Not sure what the final VC's are, occupying the hill or something else? Also where do the Centurions enter?

Looks like to can isolate the flanking AT guns so that only one can fire within normal range while the others can only fire are long range. I would look to get them to fire individually on the approaching armor and have a leader ready to spot with the heavy artillery. You maybe able to get 1 or 2 out before the Centurions arrive. Your INF's will need to hurry up to support the tanks against the British line.
