Eons ago adultery was definitely considered a no-no.

Naughty Soldiers: What Does the Military Consider ‘Immoral Behavior’?
Slate.com
by Christopher Beam
Gen. Peter Pace, chairman of the Joint Chiefs of Staff, compared homosexuality to adultery in an interview with the Chicago Tribune on Monday. “We prosecute that kind of immoral behavior,” he said. What other kinds of immoral behavior does the military prosecute?
You name it. Bigamy, sodomy (with either gender), wrongful cohabitation, gambling, dueling, indecent exposure, indecent language, indecent acts, pandering, prostitution—all of these are considered crimes under the Uniform Code of Military Justice. If you’re an officer, you’re also subject to “What other kinds of immoral behavior does the military prosecute?”
a general prohibition on “conduct unbecoming an officer and a gentleman.”
This rule, as interpreted in the military’s 900-page courts-martial manual, can be used to prosecute things like cheating on tests, stealing, public drunkenness, failing to support your family, and reading someone else’s mail. To top it off, the military can also prosecute anyone for anything that damages the “good order and discipline in the armed forces” or makes them look bad.
What I’m saying is that I’m sure there are things that are put into place for disciplining for adultery but IN MY EXPERIENCE (as a Marine wife, living on base, and in the military “system” for 13 years) they do not pursue that sort of discipline.
On the other hand, as listed, they would not overlook a Marine that was not supporting their family.
Wasn’t there a Navy pilot, a woman, who lost her commission a few years ago because she had an affair with a married man?
