You could tell he wanted to say what it was but held off in doing so due to his oath. Gotta admire that.
I know of one of his missions. It was kind of well known.
That's the way they are. Our C-130 unit transported a lot of SEALs over the years and not once did any of them ever talk about any mission they had ever been on. The only mission I know about was the one to the Mustang Ranch, and only because we had rental cars and were their transportation there.
I worked on a project with a guy who was one of the original members of Delta. We figured he was ex-military but not until it was over and I saw his CV I know.
Also knew a guy who was a 60’s Green Beret. He never said anything about what he did.
Its not fun not being able to tell people what you’ve done.
