Relieved while investigating. She hasn't been discharged yet. Even still though, she should be or atleast giving an Article 15 (that leads to loss of rank, extra duty, etc)..
If while she posed, she didn't inculde that she was miltary it probaly wouldn't be as bad. You can't run for nor advocate for anything while in uniform or using the military as a source. Also I can't remember where, but the UCMJ Uniform Code of Mil Justice does talk about pornography, and how it's not allowed. Also, she is a Staff Sergeant, that alone means she is to be held to a higher standard.
