Tet Campaign Commemorative: "Honors all military personnel who served in the TET Campaign." (Tet is a National Holiday in Vietnam with Tet Offensive happening in 1968, didn't it? So what year do they consider THE Tet Campaign, that's commemorative?)

Honorable Service Commemorative: "Honors all Armed Forces members who recieved an Honorable Discharge from active, guard or reserve forces."

Listed above are medals that a large majority of todays living veterans might, by definition be elligible for but are not listed on a DD-214. I question, can and should they be displayed as "earned" Military Decorations? Or maybe the Wannabe can just buy them at Medals of America, a pawn shop or the corner store and then brag about being a "decorated" veteran.
