From the National Security Act of 1947 to the intelligence and security restructuring after September 11, 2001 (9/11), our nation has stood up new security organizations to meet new challenges. On October 10, 2010, my team and I helped give life to a new U.S. security organization when I assumed command of the United States Army Cyber Command. As its first commander, I was more than "present at the creation;" I was responsible for it. In a crowded, yet resource-constrained defense establishment, Army Cyber was responsible for all Army cyber efforts-not only in relation to U.S. Cyber Command, but also the Department of Defense and U.S. Intelligence Community. A single-page General Order from the Secretary of the Army served as the command's founding document and mission statement. Army Cyber Command was designated the lead for Army missions, actions, and functions related to cyberspace.
