Night vision and termal vision could be nice for helmet switchable with the mobiglass and maybe some improved version for pilot/co pilot seat and turrets. The heat signature gameplay is already a thing, why not giving us the tool to see it visualy. ie: performing a ground assault with an hammerhead in support fire, turret gunners/and pilots could have a better view on the battlefield from the air and from the advanced night/thermal vision equipement and targetting software than the guys on the ground with their helmet with standard NVG and maybe some thermal. That way they could lead ground troop from up there. There could be special armor lighter with less armor with the capacity to reduce your heat signature to make you invisible to thermal equipement wich would be suited for special striking force/pirate etc.
