I don't know but I would think that the DD214 itself may also come into question? Is the one displayed on the web site a reissue? If a DD214 is reissued for some reason is it given a new number or a extension to the number?
Corrections to a DD214 are done by issuing a DD215 form.
On Kerry's DD215, issued in 2001:
1) His Silver Star is listed "with combat V". This is bogus. The Silver Star is never issued with the V device and never has been. He did not wear a V device on it when he appeared on Meet the Pres in 1971.
2) His Vietnam Service Medal is listed with 4 campaign stars. He was entitled to only 2 based on his time in-theater. He wore only 2 of them on it on Meet the Press.
