Asiatic–Pacific Campaign Medal founded by Franklin Delano Roosevelt
The Asiatic–Pacific Campaign Medal is a United States military award of the Second World War, which was awarded to any member of the United States Armed Forces who served in the Asiatic-Pacific Theater from 1941 to 1945. The medal was created on November 6, 1942, by Executive Order 9265 issued by President Franklin D. Roosevelt. The medal was designed by Thomas Hudson Jones; the reverse side was designed by Adolph Alexander Weinman which is the same design as used on the reverse of the American Campaign Medal and European-African-Middle Eastern Campaign Medal.
There were 21 Army and 48 Navy-Marine Corps official campaigns of the Pacific Theater, denoted on the suspension and service ribbon of the medal by service stars which also were called "battle stars"; some Navy construction battalion units issued the medal with Arabic numerals.  The Arrowhead device is authorized for those campaigns which involved participation in amphibious assault landings. The Fleet Marine Force Combat Operation Insignia is also authorized for wear on the medal for Navy service members who participated in combat while assigned to a Marine Corps unit. The flag colors of the United States and Japan are visible in the ribbon.
The Asiatic–Pacific Campaign Medal was first issued as a service ribbon in 1942. A full medal was authorized in 1947, the first of which was presented to General of the Army Douglas MacArthur.  The European Theater equivalent of the medal was known as the European-African-Middle Eastern Campaign Medal.
