(Shrug) The assertion was that there is no way for a citizen to sign away their First Amendment rights. The UCMJ is a valid counterexample.

That's not exactly true, your freedom of speech rights are limited by UCMJ, especially under Articles 82, 88, and 134, but not eliminated. You still have a right to attend peaceful demonstrations and such. It is, however, shameful how we treat military men and women in this country. As far as I am concerned, they should have just as many rights as any one else.

Also, it's not really a counterexample, because you do not sign away your rights when you sign the enlistment papers, you loose some of your rights by simply being part of the military. People who where drafted back in the 60s also lost had their rights limited, even though they did not voluntarily sign any papers or agreed to anything.

Further, this is an act of the government, and not a civil contract. No CIVIL CONTRACT can take away ANY of your constitutional rights.

It's not that you lose them outright, but they can be deliberately waived in certain contexts. Here's an example:

> But (if I understand correctly) in the military, you aren't subject to civilian law. You're subject to the Uniform Code of Military Justice, and civilian law does not apply to you.

Civilian law generally applies to active duty military personnel the same as to anyone else (though some laws have express exceptions or alternate provisions for military personnel), and the UCMJ even provides for the delivery of military personnel accused of violations of law by the civil authorities to be delivered to those authorities. [UCMJ Art. 14, 10 U.S.C. Sec. 814]

More to the point upthread, members of the military retain First Amendment rights, and military regulations have been struck down for violating the First Amendment.

There has been a few cases of military "whistleblowers" contacting their Congressional representative. Trying to restrict such contact I'm almost certain is a violation of the UCMJ. Contacting the Army/Navy/AF/DoD-OIG is another method of contact that is protected by Federal law.

Its not unheard of for senior officers' careers to be ended after a negative OIG report.
