None of the nano units from your barracks are really worth it (MAYBE plasma tank)

As for the promos, I'd get the legendary animals (3LSWs,2LRs and 1 LM, 1 LB) - This depends on the amount of nanos you have! - as well as 1 (maybe 2) mech tanks, no more.

Snow Crusher is decent but you don't really need it, Mech Arty is decent as well get one if you have the nanos to spare (Not a MUST though)

Yeah basically save the nanos if possible and wait for new promos - Never spend for the sake of spending!
