Sounds interesting, however actual testing sounds a handful of years away and a fully sealed helmet sounds impractical.

Maybe a new helmet reinforced with carbon nanotubes/some new light weight incredible strong fiber, and new light weight body armor.

I could see a pair of sunglasses with built in led screens and linked wirelessly to a computer. But i think the author is thinking a little to deep into halo or star wars.

You don't need a sealed suit as no one will be fighting in zero g environments ect. Or a sealed helmet.

It will have to be compatible with the army's future soldier/advanced warfighter program.
