last i played that map, it was fun. Hard, but fun. My standard crew is 2 medics, 2 snipers, 2 flamers, 1 Assult Rifle and 1 Machine Gun. One sniper guarding the back (Toward entrance), one gunner looking further down the way (Away from entrance) last sniper guarding closest dead end (That seemed to be where most aliens were. One gunner made his way to the hill in the corner, while medics are 1) At the dropship close to the stationary guys, and one following the gunner going to the hill. Just hang tight, let your snipers move maybe 1 tile per turn, always have them crouched. I have the luck of saving two or three civs
