Alot of people complained that the autobots should not need our military(or NEST) to help whoop some decepticon ass but there's one thing that everyone seems to forget: these are the only autobots on earth vs a never ending decepticon army. Seriously, how do you think they lost cybertron in the first place? If the autobots had no human military allies i'm pretty sure they would be scrap by the end of movie 2 (example: Ironhide, although had big guns, could barely hold off bonecrusher's clone and a few drones while telling sam to head for the pillars. I'm also pretty sure without military help, devastator would screw all of them(skids and mudflap fought him but it appears devs was completely intact. Also in DOTM, one soldier fired a missle that sent Sentinel packing when Bee and Swipe could barely even touch him, including Optimus couldn't even touch him until he was weak!) It actually adds to realism IMO, contrary to what everyone else thinks. Sure there are some balance issues here and there but all 3 movies show that the military cant handle their own against cons without the bots, and vise versa for the bots.
