Thanks guys. he was apparently quite the bullshitter around Georgetown and the military history crowd. It appears that young Mr. Carallo was taken in hook, line and sinker while a student at Georgetown.
Jessup is cited in a Georgetown web page as being:
Col. John Jessup, U.S. Army Ret. (G'64, Ph.D.'70) (former Commandant, G.U.R.O.T.C.)
Commandant? There is no such T.A.D. position. The senior member of the ROTC is the Professor of Military Science. Sounds like a faculty / honorary position.

So with a degree from Georgetown (University of Maryland?) in 1964, and a Ph.D. from 1970, he appears to have spent much of the Viet Nam era at Georgetown University.
Moreover, the book he supposedly wrote on military history contains the following preface (see page 10):

In which he recites that from 1971 until he retired in October 1974 he was with the Office of the Chief of Military History.
And finally, there is the rendering he gives of his Korean service at his retirement home in Florida.
Carefully read the paragraph on page five, and then pick up with his non-Ranger service in Korea:

You would think that a historian would do a better job of writing at least plausible fiction.
