US Marines have been issued with new social media guidelines after the recent revelation that nude photos of servicewomen had been posted online without their permission.

They highlight that "Marines represent the Marine Corps at all times", and their actions must consistently embody its ideals.

The new guidelines say:

"Marines should think twice before engaging in questionable online activities, and must avoid actions online that threaten the morale, operational readiness and security, or public standing of their units, or that compromise our core values."

They also specify that even though Marines are considered to be "often in the best position to share the Marine Corps story", they "must never engage in commentary... that harm[s] good order and discipline or that bring[s] discredit upon themselves, their unit, or the Marine Corps".

The document was approved by the Commandant of the US Marine Corps, General Robert B. Neller, who previously condemned the actions of those involved in the investigation in a Facebook video:

"If you can’t or are unwilling to commit to contributing 100% to our Corps' warfighting ability by being a good teammate and improving cohesion and trust then I have to ask you, "Do you really want to be a Marine?"

The Naval Criminal Investigative Service is investigating and officials say the images have now been taken down from the site.

However, the page has now almost reached 30,000 followers.

The photo-sharing allegedly began shortly after the first Marine infantry unit was assigned women in January.
