The Pentagon has proposed closing 33 of the 318 military bases in the U.S. It would also add 400 employees at 49 other bases. Officials say the move would "align base structure with the force structure that is expected to be needed over the next 20 years." Closing the bases would cost $24.4 billion, but would save $5.5 billion annually. The plan still needs approval by an independent panel and the president. Also, Congress could prevent the closings by voting down the entire list of bases.
