Since ATMs are all about positiong, you want to be as fast as you can and with nice handling and jump capabilities. I need to test this build, but on paper you have anything you could be willing to: good non-ATM mid range DPS and application, some cooling (but you will overheat quickly if you keep on alfa strike all the time) and nice maneuverability. Use your jump jets to poptart with your ATMs: UAV is recommended so you can see and (most importantly) lock anyone approaching your cover and fire at him a 72 damage volley.
