Inter-American Defense Board Medal

The Inter-American Defense Board Medal is an international military award which was created on December 11, 1945, by the 91st session of the Inter-American Defense Board, a Pan-American defense group devoted to the security of the member countries of the Organization of American States.
The Inter-American Defense Board Medal is awarded to any military officer, serving in a member nation of the Organization of American States, who completes a tour of service with the Inter-American Defense Board. The award is also presented to military personnel who serve on the staff of the IADB Chairman, Secretariat, or for those who complete instructor tours at the Inter-American Defense College.
The Inter-American Defense Board Medal is a one-time decoration but may be upgraded with inch silver and gold stars depending on the length of time an individual serves with the Inter-American Defense Board. A silver service star or bar is awarded for one year of service; a gold service star or bar for two; two gold stars or bars for between three years and five; and three gold stars or bars for more than five years service. U.S. military personnel who have been awarded the Inter-American Defense Board Medal and ribbon may wear them when attending meetings, ceremonies, or other functions where Latin American members of the Board are present.
