As for Women in combat. It was not merely an issue of sex in the unit.
As for the other stuff;
ART. 125. SODOMY

(a) Any person subject to this chapter who engages in unnatural carnal copulation with another person of the same or opposite sex or with an animal is guilty of sodomy. Penetration , however slight, is sufficient to complete the offense.

(b) Any person found guilty of sodomy shall be punished as a court-martial may direct.
Applies to everyone. Article 120 deals with rape and carnal knowledge, but as of 2006 was changed. The new article can be found at http://usmilitary.about.com/od/justi.../art120new.htm It list 36 specific offenses. which is why I did not post it.
ART. 134. GENERAL ARTICLE

Though not specifically mentioned in this chapter, all disorders and neglects to the prejudice of good order and discipline in the armed forces, all conduct of a nature to bring discredit upon the armed forces, and crimes and offenses not capital, of which persons subject to this chapter may be guilty, shall be taken cognizance of by a general, special or summary court-martial, according to the nature and degree of the offense, and shall be punished at the discretion of that court.

Anything that affects discipline can come under this article, including consensual sex.

On the other hand, if there are sexual relations going on within a unit, a soldier (man, woman, gay, lesbian, straight, etc) might not have his/her head completely in the battle if he or she is concerned with the safety of a loved one that is fighting side-by-side with said soldier. I believe this more than anything is the concern of the government. However, that door has already been opened by allowing women to serve in combat, so because that line has already been crossed, I feel that this specific argument is moot. If the argument is used that being forced into combat with someone who's sexual orientation makes said soldier uncomfortable, then the government MIGHT win that case, because there are enough "touchy-feely" people out there to stand behind this issue. I believe though that the military (whichever armed force the soldier serves in) instills enough maturity and bolsters patriotism to the point it overrides any misgivings about another person's sexuality.
