Too much tinfoil? Here's my summary:
There are 3 citations. See Link for text and source:

Zumwalt left his post in May 1970.
Hyland left his post in December 1970.
Therefore, 2 of the 3 citations had to be awarded in 1970 or prior.
The Lehman version is almost identical to the Hyland version.
In substance, it revised nothing.
It is still a curiosity as to why it was created some 14 years later.
I tell you why he had the Lehman copy prepared: It removed reference to shooting a fleeing kid behind a hootch, something not very brave for a war hereo to be awarded for!
