Ft. Buchanan, PR.

Fort Buchanan, located near San Juan, Puerto Rico, was established in 1923 as a military post to support the United States Army operations in the Caribbean region. Initially serving as a sub-post to Fort Brooke, it became a critical logistics and training hub during World War II, supporting operations throughout the Caribbean and Latin America. Over the decades, Fort Buchanan evolved into the primary U.S. Army installation in Puerto Rico, providing support to reserve and active-duty forces, as well as serving as a center for disaster response coordination. Today, it continues to play a vital role in regional security and support operations under the U.S. Army Installation Management Command.
