I just bought a sealed dvd from Goodwill called "The Road to War: General Patton's Desert Training Center".

On the front cover it says that the production company is Paul Kiener Productions.
On the back, it has no UPC#.
On the back, towards the bottom it has the following.
A Paul Kiener Production
in association with
The First Composite Group, Assoc.
Written by Paul W. Kiener and Richard K. Oierce
Produced by Donna L. Anderson
Filmed and Directed by Paul W. Kiener

I opened it up and the dvd is a Staples DVD+RW.

I did manage to find the site that sells it.

I'd credit those 2 groups (the ROTC and the High School students). I would do it like you would a band. It's been a while, but I'd put the name in one line rather than break it up into first and last names. If you could find out who was in those two groups, you could use the credited as function, but I think at this point, that would be virtually impossible.

No to wranglers. They aren't in the accepted crew list.
