That's small potatoes stuff in the grand scheme of things. If they eliminated the duplication of effort, sheer amount of "management" in the DoD, and revamped the contracting/award process they could probably save half of what we pay every year.
It's amazing how many levels of management there are in virtually every organization and how little it actually brings to the table.
No "non-DoD" entity would ever have organizational structures to match - they'd be out of business in no time. Well, unless they're DoD contractors because Congress has made the award process so ridiculous that businesses can add heinously high G&A costs and get reimbursed for them by the American taxpayer.
