N3rull is right. Something definitely seems amiss in regards to airpower. It's pretty annoying when you build about 5 tac bombers and send them up against a lone tank or artillery piece and they all get shot down. The other thing I noticed is that battleships are can knock out everything in no time. Park one next to a city with 10 units and they'll all be dust in 2 turns. Also lower level transports knocking out top tier destroyers. Game is a lot of fun though and I'm hopeful that this beta stage will sort out all this stuff.
