My interperation of what Delphi said is that you buy squads for your SD. Say you buy three. You begin the fight and take casualties, you lose 1 squad. Your SD will slowly regenerate the squad. At least that's what I think. Of course, that does sound a bit odd, so i dont think it's right. EDIT: After reading a bit, i think i would agree more with the SD coming with free TIEs. I bet that's what delphi meant.
