space marines

Unlike the Air Force, Navy and Army, all three of which sponsor expensive satellite programs, the cash-strapped Marines are pushing just one space concept. It's called Small Unit Space Transport and Insertion, or SUSTAIN, and it's a reusable spaceplane meant to get a squad of Marines to any hotspot on Earth in two hours -- then get them out. The idea is to reinforce embattled embassies, take out terrorist leaders or defuse hostage situations before it's too late. "The Marine Corps needs [this] capability," Brig. Gen. Richard C. Zilmer told Congress in 2004.
