This isn't a comic-book story, but plausible scenarios based on actual military projects today.
In the next generation, our warfighters may be able to eat grass,communicate telepathically,resist stress, climb walls like a lizard, and much more. Impossible? We only need to look at nature for proofs of concept. For instance, dolphins don't sleep (or they'd drown); Alaskan sled-dogs can run for days without rest or food; bats navigate with echolocation; and goats will eat pretty much anything.
