This is apparently what the ROK Army will be wearing in the field should they ever need to...

I can't describe it any better than the article does, really, especially the term "Halo-esque", but the highlights are...

Full-head helmet, with HUD, GPS and sensor cluster.
Full-body climate control.
Chem/bio-resistant.
Combo machine gun / grenade launcher / RPG launcher with laser artillery-paint thingy.

The future is now. Flying cars be buggered.

Seriously, this is the sort of shit the USA should be coming out with, if only for special operations. Mr Bush, it's time to call in a delivery order before the new guy gets in and starts arming our guys with flowers and harsh language.
