Man, way to go, thanks.
I had a martial arts friend that was into under water fighting, and although I was a ex-land based soldier (this was the 1970s) I had never even thought of what it took to defeat someone under water, at that time. I was impressed by him (after he convinced me it existed) and I will look at this.
Thank you, and thanks to another of America’s heroes.
Bookmark. Very interesting. Thanks. My dad was UDT 12.
