I believe that is not a WWII Medal. I too, have the exact same medal and ribbon set from when I was in the Air Force. So don't pass it off as WWII memorabilia.
Actually you still get good conduct medals. The medal was first intended to be a "blanket campaign medal" awarded to service members who served honorably during a designated time period of which a "national emergency" had been declared during a time of war or conflict.
The National Defense Service Medal is authorized for the following time periods:
Korean War June 27, 1950 – July 27, 1954 Vietnam War January 1, 1961 – August 14, 1974 Persian Gulf War August 2, 1990 – November 30, 1995 Global War on Terrorism September 11, 2001 – Present
and no this doesn't look like its WWII as I also have the same medal.
