If it's got a strong solid line, I'll pick a single hex that I can get on three sides of, hammer it with air, attack it from the first and third side, then advance with the units in the second side, and have them attack forward, then convert and advance the attached multi-mode units, then attach some armor units to them.
Is attacking with 6 instead of 9 divisions enough then? I rarely have success with that, but you prepeare as you say for a couple of turns, hence have stronger divisions I guess?
Your air hammering of the unit, is that on that specific hex only, or do you interdict behind the front line as well?
What type of Aircraft do you use when attacking units?
