The proposal, part of the Corps's push toward greater speed and flexibility, is called Small Unit Space Transport and Insertion, or Sustain. Using a suborbital transport-that is, a vehicle that flies into space to achieve high travel speeds but doesn't actually enter orbit-the Corps will be able, in effect, to instantaneously deliver Marine squads anywhere on Earth. The effort is led by Roosevelt Lafontant, a former Marine lieutenant colonel now employed by the Schafer Corporation, a military-technology consulting firm working with the Marines. Insertion from space, Lafontant explains, makes it possible for the Marines-typically the first military branch called on for emergency missions-to avoid all the usual complications that can delay or end key missions. No waiting for permission from an allied nation, no dangerous rendezvous in the desert, no slow helicopter flights over mountainous terrain. Instead, Marines could someday have an unmatched element of surprise, allowing them to do everything from reinforce Special Forces to rescue hostages thousands of miles away.
