5. Background: a. The National Defense Service Medal (NDSM) was established by President Eisenhower per Executive Order 10448, dated 22 April 1953, for service between 27 June 1950 and a date to be announced. On 17 June 1954, the Chief of Staff approved establishment of 27 July 1954 as the termination date for award of the NDSM. Executive Order 11265, dated 11 January 1966, amended Executive Order 10488, to include a termination date and authorized the Secretary of Defense to establish periods of eligibility subsequent to 31 December 1960. Eligibility for award, commencing with the period after 31 December 1960, was established by DOD Directive 1348.7, dated 1 April 1966, and terminated effective 15 August 1974, per letter from Manpower and Reserve Affairs, subject: Termination of Eligibility for the National Defense Service Medal, dated 30 June 1974. The NDSM was again authorized by memorandum, dated 20 February 1991, from Secretary of Defense Cheney for active service on or after 2 August 1990 with no termination date established. The termination date was later established as 30 November 1995.

b. The Heraldic Division, Quartermaster General’s Office, was requested to provide proposed designs for the NDSM and designs created by Mr. T. H. Jones were submitted to the G1 on 26 May 1953. A committee appointed by DOD, which included representatives of all services, met on 27 May 1953 and 3 June 1953 and selected the design for final approval. The eagle, our National emblem, together with the shield of the Coat of Arms of the United States is used to symbolize the defense of the United States. The combination of oak and palm leaves signify strength and preparedness.
