A Marine in uniform hands out flags in front of a group of sailors as they march in the gay pride parade Saturday, July 21, 2012, in San Diego. For the first time ever, U.S. service members marched in a gay pride event decked out in uniform Saturday, after a recent memorandum from the Defense Department to all military branches made an allowance for the San Diego parade - even though its policy generally bars troops from marching in uniform in parades.
