These are my father's medals from World War II.
The long blue medal with the rifle and the wreath is the Combat Infantrymans Badge (CIB). Directly underneath the CIB, on the left is the American Campaign Ribbon, and on the right is the Victory In Europe Ribbon (star devices additional awards). Underneath these is, the 70th Division (his parent unit) on the left, and the Good Conduct Medal and Ribbon on the right. Underneath these is the WWII Victory Medal, and on the right is the European-African-Middle Eastern Campaign Ribbon (the stars are additional awards of the same medal).
