I was a Vietnam tank commander 1968-1969. I am an international award winning author. All profits from my 7 books are donated to veterans organizations. I just finished a documentary on tanks called Tanks a Century of Dominating the Battlefield. It starts in WWI and follows American tanks to today's M1A1. As far as I know it is the only film made by people who served on tanks. It s extremely informative about American tanks. The outstanding music score was done by the very talented Christopher Duddy. This is my first attempt at producing a film. A great educational film.
