2-11. Antarctica Service

1. The Antarctica Service Medal (ASM) was established by Public Law 86–600 (DA Bull. 3, 1960).
2. The ASM is awarded to any person who, after 2 January 1946 and before a date to be announced, meets any of the following qualifications:
   1. Any member of the Armed Forces of the United States or civilian citizen, national, or resident alien of the United States who is a member of a direct support or exploratory operation in Antarctica.
   2. Any member of the Armed Forces of the United States or civilian citizen, national, or resident alien of the United States who participates in or has participated in a foreign Antarctic expedition in Antarctica in coordination with a United States expedition and who is or was under the sponsorship and approval of competent U.S. Government authority.
   3. Any member of the Armed Forces of the United States who participates in or has participated in flights as a member of the crew of an aircraft flying to or from the Antarctic continent in support of operations in Antarctica.
   4. Any member of the Armed Forces of the United States or civilian citizen, national, or resident alien of the United States who serves or has served on a U.S. ship operating south of latitude 60 degrees S. in support of U.S. programs in Antarctica.
   5. Any person, including citizens of foreign nations, not fulfilling any of the above qualifications, but who
      participates in or has participated in a United States expedition in Antarctica at the invitation of a participating United States Agency. In such cases, the award will be made by the Secretary of the Department under whose cognizance the expedition falls, provided the commander of the military support force, as the senior U.S. representative in Antarctica, considers that the individual has performed outstanding and exceptional service and shared the hardships and hazards of the expedition.
3. Personnel who remain on the Antarctic Continent during the winter months will be eligible to wear a clasp or a disc as described below:
   1. A clasp with the words "Wintered Over" on the suspension ribbon of the medal.
   2. A 5/16 inch diameter disc with an outline of the Antarctic continent inscribed thereon fastened to the bar ribbon representing the medal.
4. The appurtenances in (1) and (2), above are awarded in bronze for the first winter, in gold for the second winter, and in silver for personnel who "winter over" three or more times.
5. Subsequent to 1 June 1973, minimum time limits for the award are 30 days under competent orders to duty at sea or ashore, south of latitude 60 degrees S. Each day of duty under competent orders at any outlying station on the Antarctic continent will count as 2 days when determining award eligibility. Effective 1 July 1987, flight crews of aircraft providing logistics support from outside the Antarctic area may qualify for the award after 15 missions (one flight in and out during any 24-hour period equals one mission). Days need not be consecutive.
6. No person is authorized to receive more than one award of the ASM. Not more than one clasp or disc will be worn on the ribbon. Antarctica is defined as the area south of latitude 60 degrees S. The ASM takes precedence immediately after the Korean Service Medal.
