National Guard of the United States
The National Guard is a reserve component of the U.S. Army and Air Force, organized by state and territory and subject to state or federal authority.
Title 10 of the United States Code: Federal law governing the armed forces, including the conditions for federal military service. Federal activation generally places Guard members under the president’s command through Title 10 authority.
Disaster response: Organized action to protect people and restore essential services after a disaster. Governors frequently deploy Guard personnel for rescue, logistics, and recovery after disasters.
Colonial militia: Local citizen forces organized in the British colonies of North America before the United States was founded. The Guard traces its institutional lineage to colonial militia companies, including one formed in Massachusetts in 1636.
Army National Guard: The land-force component of the National Guard and a reserve component of the U.S. Army. It is the Army branch of the broader National Guard structure.
Title 32 of the United States Code: Federal law authorizing National Guard service under state command with federal funding. It permits federally supported Guard missions while governors retain command.
Civil disorder: Public unrest involving disturbances such as riots, violent demonstrations, or widespread breakdowns of order. State authorities may deploy Guard units to support public safety during severe unrest.
Militia Act of 1903: A U.S. law that reorganized the militia and established a more formal relationship with the federal military. It helped create the modern National Guard by defining federally recognized state forces.
Air National Guard: The air component of the National Guard and a reserve component of the U.S. Air Force. It provides the Guard’s aviation and air-defense forces.
State defense force: A state military organization that operates under state authority and cannot be called into federal service. Unlike the National Guard, state defense forces remain outside the federal armed forces.
Overseas contingency operations: U.S. military operations abroad, often involving combat, security, or stabilization missions. Guard units deploy overseas alongside active-duty forces for federal missions.
