It's not easy to assess the size or exact value of our empire of bases. Official records on these subjects are misleading, although instructive. According to the Defense Department's annual "Base Structure Report" for fiscal year 2003, which itemizes foreign and domestic U.S. military real estate, the Pentagon currently owns or rents 702 overseas bases in about 130 countries and HAS another 6,000 bases in the United States and its territories.

. The military high command deploys to our overseas bases some 253,288 uniformed personnel, plus an equal number of dependents and Department of Defense civilian officials, and employs an additional 44,446 locally hired foreigners. The Pentagon claims that these bases contain 44,870 barracks, hangars, hospitals, and other buildings, which it owns, and that it leases 4,844 more.

These numbers,

do not begin to cover all the actual bases we occupy globally
