Ok, So I am making a shadow box of all my dads military medals and ribbons. I have come across one that I do not know what it is. any help would be appreciated. For further background... my dad was in the Navy - 1957 - 1967 (Deisel and Nuke submarines) and the Army 1967 - 1978 (Transportation, i.e. boats.) He had 2 tours in Vietnam. 68-69, 70-71. Hope this help, so I can finially figure out what this is.
