The U.S. military must train personnel and test new technologies to defend the United States, its territories, and its interests
The land, air, and sea areas of the Mariana Islands are important to members of the military and their families who call the islands home. The U.S. military, including the Marine Corps, Navy, Air Force, along with the Coast Guard, conducts military readiness activities in designated areas. These areas collectively comprise the Mariana Islands Range Complex.

The islands are an ideal setting because of their location in the Indo-Asia-Pacific region, allowing the military to maintain a global and strategic presence. Every day, the military strives to reduce its effects on the environment while ensuring the United States and its territories are protected and safe.
