“But, so long as you don’t issue such opinion as an official opinion, disciplinary actions are RARELY ever taken.”

You seem to be in agreement with Counsel. From the article:

“There are restrictions on time, place and manner. For instance, service members can’t go to political rallies in uniform,” Callahan said.

But he added: “I have never seen the military go after a junior service member for making disparaging remarks about any politician.”

I would say that his statement is accurate. In 25 years, I never saw any enlisted man charged with such a violation. I have seen a couple of officers face such charges, but only two that I can even remember hearing about.

Their is a DoD directive that gives explicit permission for service members to express opinions in letters to the editors. They may identify themselves and the rank that they hold so long as they're clear that their remarks are not being made in an official capacity. I would think that a Facebook page is very far removed from a letter-to-the-editor, IMHO.
