Someone else recently asked about this guy on another forum (www.fmatalk.com)
As was pointed out there, Paul Vunak has instructors who have been with him a long time and could teach a full spectrum of material. BUT, Vunak also offers a two day instructor course on his RAT (rapid assault tactics) program, which is a very condensed down and dirty combatives approach. After the two days you are an apprentice instructor in Vunak's organization (when you pay the fees).
Moran's description of what he does sounds like he did the two day course, and is listed as an app. instructor on Vunak's site.
