A proper look at WWII history would show that is exactly what Rommel did to the British... he pushed well past the so called "front line" deep into territory supposedly under British control and hit them at the core of their army, where the command posts and fuel depots were.
Anyways, I prefer a role-played border as well, I was just putting in a suggestion if we ever did make borders a hard-coded reality. So we're arguing over semantics.
