"For starters the use of his military rank." What do you mean here?

"He must file individually in a suit not as part of an identifiable political action." Do you have legal reference for this requirement? Or, is this your opinion?

"There are words used in the “letter” that disparage the Pres. and that's an offense covered under the UCMJ." Can you provide the wording and the UCMJ 'part' that would cover such wording?

"There is also conduct unbecoming of an officer as well as conduct detrimental to the good order and discipline of the military both UCMJ offenses." Same as above. Linking UCMJ offense to conduct unbecoming of an officer?
