U.S. Northern Command (NORTHCOM) is a major unified command of the U.S. Department of Defense. Established in 2002, its primary mission is to protect and defend the U.S. homeland and support civil authorities during emergencies. NORTHCOM oversees military operations in North America, including the U.S., Canada, and Mexico. NORTHCOM coordinates with various agencies, such as the Federal Emergency Management Agency (FEMA) and local law enforcement, to ensure a unified response to threats. It also plays a role in disaster relief efforts, helping communities recover from natural disasters like hurricanes and wildfires.
