Yea, I know... There are so many OPSEC posters around here with s**t like that. Saying how your email isn't private etc etc. Because we are all at threat of "terrorists" hacking into our stuff and reading sensitive information. (OPSEC = Operations Security)
When my work laptop has the screensaver come on it's just a bunch of OPSEC ads the whole time, and we even have them on TV on the AFN (Armed Forces Network) instead of commercials. We don't get real commercials out here. It's all replaced with military s**t.
