You gotta take artillary without a doubt; It's something I rarely did in Civ3 and I only just realised how good it was after playing for about 2 years. In Civ4 artillary is very very useful. Use your fighters to take out his then bomb the defensive units (I just love collateral damage), then use artillary to take down his cities defences. It may take 2 turns, but with that many modern armour you won't have the slightest problem in winning.
