Final Part of "Demo Dick" Marcinko Richard “Demo Dick” Marcinko was one of the most controversial SEALs in history— but also one of the most impactful.

He pushed boundaries, thought differently, and left a lasting footprint on Naval Special Warfare. If you enjoyed this series on Richard "Demo Dick" Marcinko, let me know
