Fort Buchanan

Fort Buchanan at a glance

Fort Buchanan is an Army garrison in Puerto Rico whose mission supports the readiness of the Total Force. Its official mission describes installation services for the military community, responsible use of resources and community support. The focus is the infrastructure and day-to-day services that enable military organizations to train and operate, rather than a single combat formation identified with the post.

The installation grew from Camp Buchanan, established in 1923 as a training area near San Juan Bay. It became Fort Buchanan in 1940 and served as a supply and personnel-processing center during World War II. Those origins help explain its long association with Army support functions in Puerto Rico and its continuing role as a garrison community.

Before you arrive

Use these questions with your sponsor or gaining organization. They are a starting point for planning, including assignments, courses and training periods that differ from a routine permanent change of station.

1. Confirm the organization, duration and reporting instructions shown on your orders. Ask which office handles your arrival.
2. Clarify lodging and housing arrangements before booking. Ask about availability, required approvals and how to handle a late arrival.
3. For an overseas assignment, ask your sponsor about family travel authorization, required documents, medical screening, pets and vehicle shipment before making reservations.
4. Coordinate household goods and personal travel with the appropriate transportation office. Keep orders, receipts and important family records together.
5. Make a short list of contacts for medical care, schools, childcare and family support, where applicable to your assignment.
