Defence Secretary Chuck Hagel has unveiled plans to shrink the US Army to its smallest size since before World War Two.
Outlining his budget plan, the Pentagon chief proposed trimming the active-duty Army to 440,000-450,000 personnel, down from 520,000 currently.
Cold War-era Air Force fleets – the U-2 spy plane and the A-10 attack jet – will also be retired.
