So is the Flak Track going to be able to shoot on the move soon now because the limit of the USF AA HT was it didn't have 360 degrees of rotation and that's gone. I don't see why the Flack Track should be the only AA vehicle in the game with a set up time, especially since it's performance against infantry got nerfed.
EDIT: To elaborate the Flak Tracks attack was changed to being Accuracy Based, making it fall off in effectiveness as the game progress but be better versus units in buildings. I don't think the M15 should have 360 suppression on the move.
TBH, the arc of the USF was pretty huge. It was more of an annoyance to have to drive backwards. Dunno what's the DPS of the MG or if they can suppress on the move, but the main source of damage comes when it's deploy. It's not that it's better rather than easier to use.
At this point i'll rather give the Flak HT plus 20-60hp. Too risky to deploy one nowadays.
