This post gives the third "Campaign Medal" which recognized the global nature of WWII involving hundreds of engagements and campaigns fought by American service personnel. The following medal called "American Campaign Medal" was awarded for service within the American Theater between December 7, 1941 and March 2, 1946.
The obverse [front] depicts a Navy cruiser under full steam with a B-24 bomber flying overhead. A sinking enemy submarine above three waves is shown under these symbols of America's coastal defenses. In the background are some buildings representing "the arsenal of democracy".
The reverse [back] shows an American bald eagle facing left, standing "defiantly" on a rock symbolizing democracy. The dates 1941 - 1945 are shown along with the words "United States of America". [This is the same for all of the campaign medals shown before.]
The colors shown on the ribbon have four wide azure blue strips. The center stripe of dark blue, white, and red represent the United States. Near each side are narrow stripes of white, red, black. The red and white represent Japan, and the black and white represent Germany.
