The Department of Defense is investigating hundreds of Marines who shared nude photos of female service members and veterans.
Dozens of women were identified by their rank, full name and military duty station in photos shared on a private Facebook page, "Marines United," according to the Center for Investigative Reporting.
Some images showed women engaged in sexual acts.
A photo posted of a female corporal in uniform garnered numerous obscene comments. One member said the service member who took the photo should "take her out back and pound her out."
Other members of the Facebook group recommended the service member engage in more than vaginal sex. "And butthole. And throat. And ears. Both of them. Video it though … for science."
House Armed Services Committee member Adam Smith, D-Wa., called the behavior "degrading, dangerous, and completely unacceptable."
"I expect that the Marine Corps Commandant, General Neller, will use his resources to fully investigate these acts and bring to justice any individuals who have broken the law and violated the rights of other service members," Smith said in a statement. "He must also ensure that the victims are taken care of."
Defense Department officials told the Center for Investigative Reporting that the photos put service members at risk for blackmail and jeopardize national security.
