Each year since 1950, the U.S. Department of Defense has provided on its web site detailed information about the deployment of American troops around the world. A study of this data shows how the U.S. military's size and scope has changed over the past 35 years: from its peak in 1969 as a conscripted force of 2.4 million troops, heavily dispersed around the globe, to today's all-volunteer force of only 1.4 million, concentrated in a handful of countries.

Broken down by administration, this data reveals how different administrations have approached geopolitical conflict. For instance, almost 750,000 U.S. troops were present in the East Asia and Pacific theater at the height of the Vietnam War, but when America declared war on Iraq twenty years later, only about 70,000 troops were deployed. When the U.S. participated in the NATO-lead war in Kosovo in 1999, air strikes were substituted for large numbers of ground forces and no more than 13,500 troops were in the immediate area-that is a fraction of the more than 200,000 troops deployed in the Middle East as part of Operation Iraqi Freedom.

The William J. Clinton Administration (1993-1996)

Note: Except where noted, troop deployments for each region are calculated as the mean of all years in a presidential administration.

Just before leaving office, President Bush authorizes the deployment of 25,000 American soldiers to Somalia to aid in famine relief efforts there. After President Clinton is inaugurated, he reduces that number to 5,000 before completely withdrawing troops after the death of 18 U.S. Rangers . Meanwhile, another 25,000 U.S. troops head to Haiti to put an end to the violence that has been building there since the 1991 coup that removed President Aristide from office. However, in 1994 the U.S. decides to send only a token number of forces to participate in peacekeeping efforts in Rwanda against the genocide that claims the lives of more than 800,000 Rwandans in 100 days . Later in 1995, American forces participate in a NATO-lead attack on Bosnian Serbs. Roughly 19,000 U.S. forces are reported as being in the three former Yugoslavian countries from Sept. 1995 to Sept. 1996. Despite interventions in three different theaters, the first Clinton administration continues its plan for military downsizing and reduces Reagan's military build-up by about 30 percent, from roughly 2,140,000 troops in 1988 to 1,470,000 by 1996.

A Note about the Data:
The Defense Department reports troop deployments at the end of each fiscal year on Sept. 30th. In the following maps, troop deployments are listed as the average, by region, for the four years of each presidential administration. The exceptions to this rule are the maps representing the Nixon and Ford administrations. Where a region's average does not adequately reflect the troop deployments over an entire administration (such as the average for East Asia and the Pacific during the Nixon administration), annual troop levels are listed instead. Whenever possible, the caption at the bottom of each map has tried to explain fluctuations in data that might skew the averages. Finally, when viewing these maps, it is important to keep in mind that the Defense Department regularly changes the names of it's geographical regions and the countries included in them. A color-coded system is used for national makeup of each region to help clarify this.
