The Governor is the ex-officio Commander-In-Chief of the Guam National Guard when not in active Federal Service.  The Governor appoints The Adjutant General to serve as the Director of the Department of Military Affairs and the Commanding Officer of the Guam National Guard comprised of the Army National Guard and the Air National Guard.

The Guam National Guard has a unique dual mission serving the Federal and State.  The Guam National Guard answers the call of the President to assist in combat and peace-time missions and the call of the Governor to assist in the island’s affairs and times of domestic emergencies.

The Department of Military Affairs is a Government of Guam agency providing administrative and operational support to the Guam National Guard.  The Department of Military Affairs and the Guam National Guard operate together within the policy guidance and fiscal framework of the Federal and State responsibilities.  With millions of dollars in Federal and State General Funds, the Department of Military Affairs through the Master Cooperative Agreement with the National Guard Bureau, ensures the Guam National Guard remains as a readiness force to serve the vital interests of the nation, the island, the local communities, and Guam’s citizens.
