The repeal notice is signed by Sgt. Maj. of the Army Ray Chandler, U.S. Army Chief of Staff Ray Odierno and Army Secretary John McHugh. The notice says it is the duty of all personnel to follow the change in policy, but also says U.S. service members are ready for the change.

"For over 236 years, the U.S. Army has been an extraordinary force for good in the world," the repeal notice states. "Our Soldiers are the most agile, adaptable and capable warriors in history — and we are ready for this change."

Frank dismissed the idea that repeal of the policy would cause chaos in the U.S. Armed Forces, and said this fear is always raised whenever efforts are made to tear down prejudicial policies.

"We have a history in this country of prejudice being enacted, and through the efforts of many people, the policy embodied in that prejudice can be overcome," Frank said. "And as we debate any single effort to overcome prejudice we are told that the effect of diminishing that prejudice, the effect of repealing that rule, will be chaos, will be disorder, will be social unrest, and it is never true."
