Gennadiy N. Lepeshkin: My brothers and my parents didn't know what I did. They knew that I was a military doctor, but they didn't know what I did specifically.
Interviewer: Why not?
Lepeshkin: Well, you know... there were security requirements, if you will, that prohibited disclosure of such information. It's just a part of military service. A pilot, for example, flies a plane, but he doesn't tell his parents and others close to him what exactly he's doing. He just flies. I was a military doctor, that's all. I work at a research facility, I do my work, but what I actually do has really nothing to do with them.
