Speaking of outing.....I had forgotten to bring this up here until I saw this thread revival.
Early January I was at a local chapter meeting for the Emergency Nurses Association. When I was there I ran into a dude who was a RN in the ED at UNC Hospitals (8 miles down the road), when he was there I knew him peripherally, though his wife and my wife were decent friends. We were in small groups and someone says to me, "hey you were in the Navy, did you know Raul (yes, real name) here was a SEAL?" My head did the quick swivel. "Really??" I ask. I follow with the standard: "What class number were you in?" Raul says, "it was way back in the 80s, we didn't have numbers, we had a winter class and a summer class." "uh huh," says I.... "that weird. My best friend Mike (real name, former corpsman) was in class 150 something, that was around 1990 if I believe. They had class numbers." So he says, "well, we had special classes without numbers...."
I didn't take it further. It wouldn't get either of us anywhere, but I made the others in the group aware that BUDS had class numbers since, well, the beginning. "Huh, isn't that something. All BUDS classes have numbers, but yours didn't? That really is incredible."
