WASHINGTON — Defense Secretary Chuck Hagel is proposing shrinking the Army, closing military bases and making other military-wide savings as part of a broad reshaping of priorities following more than a decade of war.

Hagel outlined his vision in a speech today at the Pentagon, a week before President Barack Obama is expected to submit his 2015 budget plan to Congress.

Under the Hagel plan, which Congress could change, the active-duty Army would shrink from 522,000 soldiers to 440,000 to 450,000.

That would make it the smallest Army since just before the U.S. entered World War II.

Hagel said the military needs to adjust to the reality of smaller budgets, even as he asserted that the United States faces a more volatile, more unpredictable world that requires a more nimble military.
