I was curious about that. I hold a green belt, 3rd, from American Mu Duk Kwan, Tang Soo Do.
Got it in college many moons ago.
Nice to meetchya.
Cool. Yeah I miss it. Our federation, ITF was also Mu Duk Kwan. I got to red belt with 2 blue stripes. Needed to rise to 4 in order to test for black belt, so was about a year away when I injured my shoulder pretty bad. That was the end for me, unfortunately.
