The United States Coast Guard Reserve was formed as a military reserve component of the United States Coast Guard on February 19, 1941. It is organized, trained, administered, and supplied under the direction of the Commandant of the Coast Guard through the Director of Reserve and Training. The reserve provides highly trained and well qualified personnel available for active duty in time of war and national emergency, and for augmentation of Regular Coast Guard forces during a serious natural or man-made disaster, accident, or catastrophe. Its personnel are trained to perform the gamut of operations as performed by active duty Coast Guard personnel. As of December 2006, the Reserve is managed by the Director of Reserve and Training, RDML Cynthia A. Coogan. Since September 11, 2001, over 8,500 Reservists have been activated and 400 Reservists are currently on active duty. All the Coast Guard's Port Security Units and most of its Naval Coastal Warfare units are Reserve-only units. The reserves perform one weekend drill a month and may perform up to 15 days active duty a year. The Coast Guard Reserve has about 8,000 men and women in service, many of them integrated directly with Coast Guard units. During the Vietnam War period and shortly thereafter, the Coast Guard considered abandoning the Reserve program, but the force was instead reoriented into force augmentation. The United States Coast Guard Reserve was originally established on June 23, 1939 as a civilian reserve. This civilian reserve was renamed the United States Coast Guard Auxiliary on the formation of the military reserve.
