OK wree the last missoing the APCs are to take over the turrets. I can't keep them both alive. First two times I ran through the game I didn't even try and they survived. I played this mission three time is a row and at least one of them dies by enemy fire. I hit all the opposing mechs to get their attention and even take damage but they still shoot up the APCs. Any insite as to how the AI works. I mean they are doing what I would do but like I said the first two time I played this game it was different.

The AI knows enough to not waste a lot of shots on targets it can't significantly damage. Try to brace up in the courtyard so you don't have much evasion, and focus your fire and bring all your damage to bear in the first two rounds. The Catapult and the Orion should be your main concerns. And of course, make sure you're in there before the APCs get there. The turrets should ignore them, so you can LOS those, but you'll need to present a target for the 'Mechs or they will knock out those APCs.

Thanks it worked this time. The only difference was I sprinted my Battlemaster twice straight ahead and that gave the enemy one more thing to shoot at.
