Marine Commandant Gen. James Conway told Military.com that single rooms need to be made in military barracks in order to prevent straight troops from living with gay troops.
"I would not ask our Marines to live with someone that's homosexual if we can possibly avoid it," Conway said.
The proposition Conway made comes in the wake of the embattled repealing of Don't Ask, Don't Tell, which makes it possible to boot someone from the military for having same-sex sexual preferences, among other things.
Last month, Conway told Congress, "My best military advice to this committee, to the secretary, to the president, would be to keep the law such as it is."
U.S. Secretary of Defense Robert Gates said the Pentagon will immediately ease up on enforcing Don't Ask, Don't Tell Thursday.
