Mario Vigil, who is married, is under investigation for committing adultery with a married woman who claims Vigil is the father of her unborn child. The information came to light after both parties sought protection orders for the other amid claims of harassment. Due to the on-going investigation, the Army removed Vigil from his position as the senior enlisted advisor in Army Special Operations Command.
Interestingly, the alleged paramour, Connie Delaine Pruitt, claims that the investigation goes beyond determining whether Vigil committed adultery (which requires a finding that the extramarital sex was prejudicial to good order and discipline or of a nature to bring discredit upon the armed forces):
The military investigation, Pruitt asserts in the court documents, is focused on determining whether Vigil broke a military law that prohibits unbecoming conduct and whether he shared classified information with her.
Since Vigil is enlisted, Article 133's Conduct Unbecoming an Officer and Gentleman doesn't apply to him.
