National Guard Fast Facts

(CNN)Here's a look at the National Guard, the oldest component of the U.S. armed forces.

Facts:
The National Guard consists of the Army National Guard and the Air National Guard.
The National Guard was formed in the 17th century as the militia of the colonists in North America.
The Marquis de Lafayette, on a visit to the United States in 1824, popularized the term "national guard" as a description for the various states' militias. The title was formalized by federal legislation in 1916.
Other reserve groups have no affiliation with the National Guard. (Ex. Army Reserve)
The National Guard takes an oath to perform state or federal missions and can be deployed for either. A governor can call up troops to assist in national disasters, and the president can order troops for federal missions both domestically and in foreign nations.
In times of peace, the National Guard trains one weekend a month and two weeks during the year.
Immediately after the September 11 attacks, 50,000 guardsmen were called up to perform federal and state missions.
Ohio Governor James Rhodes called up approximately 100 Ohio National Guardsmen in May 1970 to disperse an angry crowd of students at Kent State University. Guardsmen shot and killed four students.
