[Lt. Ketch]

Change the Map! If that's possible. I figure that I wouldn't land my troop in that situation, so it only makes sense to relocate the landing. I'd run a couple of support tanks through the south with some leg infantry just to "keep them honest." Be present so the enemy has to keep forces in place there to keep you from flanking him. This will enable your northern force to avoid being overwhelmed by the enemy in rough terrian. I realize you're playing the AI and you can't psych it out (it's like trying to stare down a LED light), but you can at least devide it's artillary and who knows, maybe the south will slip through.
