The U.S. Army, Navy, Air Force, Coast Guard, as well as the Canadian military have begun an extensive annual field training exercise for the U.S. Northern Command.
“Operation Vigilant Shield 12” is the biggest multi-spectrum, high-level exercise for the North American Aerospace Defense Command and U.S. Northern Command. Northern Command is a Unified Combatant Command of the United States military, formed in the aftermath of the Sept. 11 attacks in 2001 to protect the United States homeland and support local, state, and federal authorities.
Operation Vigilant Shield 12, or VS 12, is a joint exercise supported by the Joint Coalition Warfare Center and conducted as a command post exercise with a supporting field training exercise in Key West, FL. The exercise is also linked to a Canada Command exercise called “Determined Dragon,” and runs concurrently with the Arizona’s “Vigilant Guard” exercise. It runs Nov. 1-10.
According to the Army, the overall exercise scenario for VS 12 is based on potential threats to the U.S. and Canada that require extensive military planning to support national objectives and provide multiple military options to the national leadership.
