Well I guess all I have to do know is wait for that mission to come back and go for it. Fair enough. Thank you guys !
The first time I had 2 tanks and at least 3 other foes facing my ship, and one of them had an RPG with a baby nuke loaded.. As soon as I was shooting or even moving a gal, they were unleashing hell on me. Now that my gals have muuuch better equipment (I sould have a few of them in Annihilator suits by the time it pops back) it should be easier (assuming I'll have less of them aiming directly at the ship on the first turn).
And take a lot of explosives with you.. rockets, panzerfaust, what you can grab.. or very good melee weapons, but be careful. getting close to some specific enemies is very dangerous and I don't talk about tanks.
Don't worry for that. In X-COM , my moto is "Always take enough explosive to blow up the entire map. Twice", and the blaster launchers that I just researched help.
