Coil whups CT, a memoir in advance (Colonels Keep Out!)

[RedDevil]

I agree, with Ivan use the cover you have to molest his advance out front and make him spend time opening holes to come thru.
Keep a reserve back to plug the area where he eventually punches thru and slow him down again.

I like to utilize the front ground with a good mix of units to slow an advance up to the point of stopping it where it benefits the attacker and make him come thru an area that he doesn't want to. In a 35 turn game, if he's still banging on the outer defenses on turn 25, you've done excellent IMO
