My name is Jason Hardy, and I am the owner of The Dog Tag. I have been collecting militaria for over thirty years. In the 1990’s, I decided to focus on US Special Forces during the Vietnam War with a heavy emphasis on Military Assistance Command Vietnam Studies and Observation Group (MAC V SOG). My collecting interest also evolved into documented items as the history is very important to me. This led to writing a book series: MAC V SOG: Team History of a Clandestine Army that are available through my web site.
