Marcus S. Glimpse, 22
As a teenager, Glimpse dropped out of high school, painted his fingernails black and sported a fuchsia mohawk. He couldn't hold a job, even at Blockbuster store 500 yards from his home where he was fired for being perpetually late. He enlisted after his twin brother became an Army paratrooper.
