Shoot 'n' Scoot !

For years, military live fire exercises have relied on either stationary or pop-out targets but they don't really simulate enemy movements—they just sit there, waiting to be shot. These targets, newly developed for the U.S. Marine Corps don't; they move, behave, and react just like real combatants.

Well, combatants who ride Segway scooters.
