These maps show the countries where the United States has a military presence (colored orange). The list of countries can be found here. The maps do not represent the number and size of the sites in each country, which vary. The functions of the sites are also various. Besides military bases, there are airfields, refueling stations, ammunition depots, hospitals, and so on. Nevertheless, the map gives an indication of the scope of the United States Military's worldwide presence.

The maps only show sites that are documented for the public by the U.S. government (see citations on the list). Two of the resources for information about U.S. military sites overseas are the Department of Defense's Base Structure Report and the Overseas Basing Commission's Report to the President and the U.S. Congress (May 9, 2005).

Some of the other countries where it is likely that the United States has a military presence are the following. In the Middle East: Israel, Jordan (Chalmers Johnson, Nemesis, 2006, pp. 140–1), and Pakistan (Overseas Basing Commission, Report, 2005, p. G11).
