The military can lift its "don't ask, don't tell" policy, which prohibits gays and lesbians from openly serving in the military, with little risk to the current war effort, according to a report by a Pentagon study group.

Sources told the Washington Post that more than 70 percent of active-duty and reserve troops responded to a survey, saying the repeal of DADT would have a positive, mixed, or nonexistent effect.

Though a final version of the report has not been released, sources who have read the report say the authors conclude that once service members were allowed to serve openly, any objections to them would disappear.

Both the Senate and House versions of the annual defense authorization bill would in effect repeal DADT. But it is not known whether the bills will be pursued in the lame-duck Congress that is scheduled to resume session next week. President Obama has also said he will get rid of DADT.

The findings came from a summer survey of 400,000 active-duty and reserve troops and 150,000 military spouses.
