From here:

Four branches of the military have begun sending training material to 2.2 million active and reserve troops as a prelude to opening the ranks to gays, with instructions on, for example, what to do if an officer sees two male Marines kissing in a shopping mall…..

The vignette about seeing two male Marines kissing is part of a list of scenarios to help instructors prepare commanders for incidents likely to arise.

“Situation,” it begins. “You are the Executive Officer of your unit. While shopping at the local mall over the weekend, you observe two junior male Marines in appropriate civilian attire assigned to your unit kissing and hugging in the food court.

“Issue: Standards of Conduct. Is this within standards of personal and professional conduct?”

The answer to Marines: “If the observed behavior crosses acceptable boundaries as defined in the standards of conduct for your unit and the Marine Corps, then an appropriate correction should be made. Your assessment should be made without regard to sexual orientation.”

Wrong answer: you should video the kissing marines. The video would then be used as propaganda material to demoralise the enemy by showing them how tough US Marines are.
