The Freedom to Serve, Freedom to Marry campaign on Sunday, Veterans Day, released a video highlighting how the Defense of Marriage Act (DOMA) hurts gay couples in the military.

In the 90-second video, titled Same Skin, a gay soldier and a straight soldier show off their military wounds. Captions read: “Gay and straight service members scar in the same way. But the military is forced to treat them, and their families, differently because of the Defense of Marriage Act.” (The video is embedded on this page. Visit our video library for more videos.)

The campaign is a joint effort between Freedom to Marry, the nation's largest advocate for the legalization of gay nuptials, and OutServe-SLDN, the leading group advocating on behalf of LGBT troops.

“Today, we remember all who have served our nation so honorably; but we reserve a special remembrance for all those who have provided the same service, taken the same risks, and made the same sacrifices to keep us safe, yet are treated as second-class citizens by the country they are sworn to protect,” OutServe-SLDN Executive Director Allyson Robinson said in a statement.

“The video we are releasing today depicts that stark reality painfully well,” she added.

Federal agencies, including the Pentagon, are not allowed to recognized the legal marriages of gay couples under DOMA, which was approved by Congress in 1996.

The law is under attack in Congress, where Democrats are pushing for repeal, and the courts, which have consistently declared it unconstitutional. Four DOMA-related cases have been appealed to the Supreme Court.

“This is a two-front war,” Robinson said. “Together, we will continue to fight in the courts and on Capitol Hill, and we will reach a day when the families of brave gay and lesbian servicemembers and veterans are treated as equals. There cannot be two classes of service members.”
