The United States military, the largest in the world, maintains a vast network of installations to support its operations. The number of Army posts, or installations, is a significant aspect of this network. But how many Army posts are there in the U.S.?

To understand this, we must first define what constitutes an Army post. The U.S. Army defines an installation as a "geographically delineated area under the jurisdiction of a commander, used to support the Army's mission." This includes bases, camps, forts, stations, and other facilities.

Army Installations in the United States
The U.S. Army operates numerous installations across the country, each serving a unique purpose. These range from training centers to logistics hubs, from research facilities to hospitals.

According to the U.S. Army's Installation Management Command, as of 2021, there are approximately 120 active Army installations in the United States and its territories. This includes installations in all 50 states, as well as Puerto Rico, Guam, and the U.S. Virgin Islands.
Army Bases by Region

The distribution of these installations is not even across the country. Some regions, like the Southeast and the Southwest, have a higher concentration of Army posts due to their strategic locations and historical significance.
For instance, the Southeast has installations like Fort Benning in Georgia, Fort Bragg in North Carolina, and Fort Stewart in Georgia. The Southwest has Fort Bliss in Texas, Fort Huachuca in Arizona, and Fort Hood in Texas, which is the largest active-duty armored post in the U.S. Army.
Army Installations by Function

Army installations also vary in their purpose. Some are training centers, like the Army's largest training center, Fort Jackson in South Carolina. Others are logistics hubs, such as the Army's largest logistics center, Fort Lee in Virginia.
Some installations are dedicated to research and development, like the U.S. Army Research Laboratory at Aberdeen Proving Ground in Maryland. Others serve as hospitals, like the Eisenhower Army Medical Center at Fort Gordon in Georgia.
Army Installations Overseas

While this article focuses on Army posts in the United States, it's important to note that the U.S. Army also maintains installations overseas. These include installations in countries like Germany, Italy, Japan, and South Korea, among others.
As of 2021, there are approximately 80 Army installations outside the United States. These installations support the Army's global operations and maintain readiness for rapid response worldwide.



















Army Bases in Europe
Europe hosts a significant number of U.S. Army installations. These include installations in countries that were once part of the former Soviet Union, like Germany and Italy, as well as in countries that were part of the former Yugoslavia, like Kosovo.
Some of these installations, like the U.S. Army Garrison Stuttgart in Germany, support the Army's European Command. Others, like the U.S. Army Garrison Italy in Italy, support the Army's Africa Command.
Army Installations in the Pacific
The Pacific region is also home to several U.S. Army installations. These include installations in Japan, like Camp Zama and Camp Fuji, and in South Korea, like the U.S. Army Garrison Yongsan.
These installations support the Army's Pacific Command and maintain readiness for operations in the Pacific region.
In the vast landscape of the U.S. military, the number of Army posts is a testament to the scale and complexity of the Army's mission. From coast to coast and around the world, these installations are a critical part of the Army's infrastructure, supporting its operations and maintaining its readiness. As the Army continues to evolve, so too will its network of installations, adapting to meet the changing needs of the 21st century."
