Are you sure you haven't changed grand company? Since doing that quest a while a go?
I'm not sure that you have do re-do Squadron and commander. But you definitely have to r do a couple of the early quests when starting one of the other GCs for the first time. And you have to re-rank for that GC. (But you never lose a tank in a specific GC once you have the rank for that GC)

If you switch GCs, you need to rank up until you gain access to the squadron again, at which point you will get your whole team back exactly as they were. Then IIRC all you need to do is send them on the two specific missions that give you promotions.
