Kinda like a mechanical goat?

Ummm, sorry but the concept of the EATR, a fighting machine that can extract biomass as an energy source, was developed long before 2003. All you need is an 18 year old kid from an economically depressed area. You just put a gun in his hand, ship him off to whatever country you're currently annoyed with, and feed him whatever biomass is available. You've got yourself a cheap, disposable, and replaceable fighting machine.
True, but if the EATR is destroyed, there's no pitiful lamentations from its whiny family since it doesn't have one. And, the EATR doesn't bring back any of those pesky and possibly incriminating memories AND it doesn't complain about PTSD.
And in case anyone in some off chance didn't catch the sarcasm dripping from what I just said, there was sarcasm dripping from what I just said.

Kinda figured that with N. Korea rattling its saber and Iran rattling its saber as well.
UPDATE: the eatr is vegan, allegedly.
