The Defense Business Board said the Pentagon can reduce its spending by $125 billion by getting rid of contracts, offering early retirements, and modernizing its business operations.

Steve Grundman is M.A. and George Lund Fellow at the Atlantic Council, and former DoD assistant secretary for industrial affairs and installations. On In Depth with Francis Rose, he said the Pentagon should be wary of following examples from those large firms.
