I suggest you have the DOD eliminate Change of Command ceremonies. Read online article: Gen. Alston takes reins of 20th Air Force, http://www.af.mil/news/story.asp?id=123212238 or 36th Wing ushers in new CC, http://www.andersen.af.mil/news/story.asp?id=123212074
After reading the articles have the GAO calculate the cost of transportation, lodging, and hours of manpower lost to have Wing formations and personnel to attend these events. These are not the only Change of Command ceremonies and the Americian tax payers fund the these expenses. Aircraft fuel alone for these trips run into the six digit figures.
