Wow. No effort to actually click on the links and read them?
I would suggest you go and read the list of movies that Humphries has worked on.
Then at least make an effort to research Chuck Pfarrer.
Simply noticing the author of "Warrior Soul, The Memoir of a Navy SEAL", published in 2004, might point out the obvious...or, more recently, the author of "SEAL Target Geronimo, The Inside Story of the Mission to Kill Osama bin Laden", published in 2011, might help as well. Could it possibly be the same guy that wrote "Navy SEALs", the movie you dismiss as comedy? Shocking!
Considering HOW MUCH just those two individuals have contributed in the past 20+ years to Hollywood, one would be inclined to realize that the movies and the books have been going on for decades, now, haven't they?
The next time you are looking at the books in the "Military" section, you might notice the names Dennis Chalker and Richard Marcinko, both of whom served with Harry Humphries. Small world, isn't it?
