The National Defense Service Medal (NDSM) was first intended to be a "blanket campaign medal" awarded to service members who served honorably during a designated time period of when a "
national emergency" had been declared during a time of war or conflict. It may also be issued to active military members for any other period that the
Secretary of Defense designates. To date, the NDSM has been awarded for four specific time periods, which roughly correspond to the Korean War (1950–1954), Vietnam War (1961–1974), Gulf War (1990–1995), and the Global War on Terrorism (2001–2022).
Establishment The NDSM was established by
Executive Order 10448, issued by President
Dwight Eisenhower, on April 22, 1953. While no document is known which explains the rationale for the award, it was apparently established to recognize all service members who served during the Korean War, to include those who did not serve in the war zone. (Service members who served in the war zone received the
Korean Service Medal, established by President
Harry S Truman in 1950.) Originally, awards of the NDSM were restricted to personnel serving on active duty and were retroactive to June 27, 1950 - the date the Korean War began.
Design The Heraldic Division, Quartermaster General’s Office, of the U.S. Army was requested to provide designs for the NDSM. A design developed by T. H. Jones was submitted to the U.S. Army Assistant Chief of Staff for Personnel (G1) on 26 May 1953. A committee appointed by the Department of Defense, which included representatives of all services, met on 27 May 1953 and 3 June 1953 and selected Jones' design for final approval. An eagle holding a sword and an olive branch (on the obverse), together with the shield of the
Coat of Arms of the United States (on the reverse), was used to symbolize the defense of the United States. The combination of oak and palm leaves around the shield signify strength and preparedness.
Eligibility changes Eligibility for the NDSM was expanded by executive orders issued in 1966 (
EO 11265), 1991 (
EO 12776) and 2003 (
EO 13293). Executive Order 11265, dated January 11, 1966, extended eligibility for the NDSM to service members "who served during any period after December 31, 1960, which the Secretary of Defense designates as being a period for which active military service merits special recognition." The closing date of this period of eligibility was later set at August 14, 1974 by a letter from the Assistant Secretary of Defense for Manpower and Reserve Affairs, subject: Termination of Eligibility for the National Defense Service Medal, dated June 30, 1974.
Status The National Defense Service Medal is the oldest
service medal (as opposed to
decorations for particular achievements such as valor or meritorious service and
Good Conduct Medals) awarded by all branches of the
United States Armed Forces. The only two older awarded service medals are the
Marine Corps Expeditionary Medal, established in 1919, and the
Navy Expeditionary Medal, established in 1936. The oldest awarded combat decoration is the
Medal of Honor, which was established in 1862, and the oldest awarded non-combat decoration is the Army's
Distinguished Service Medal, established in 1918. The Navy, Marine Corps, Coast Guard and Army Good Conduct Medals were established in 1869, 1896, 1923 and 1941 respectively. The
Selected Marine Corps Reserve Medal was established in 1925. As the NDSM has been awarded to all military personnel during four wartime periods spanning 72 years, it has millions of recipients and is the most widely awarded medal in the history of the United States Armed Forces. ==Periods of eligibility==
