The History of the Army Cyber Command

Army Cyber Command is an operational-level Army force reporting directly to Headquarters, Department of the Army (HQDA). The Commander, U.S. Army Cyber Command (ARCYBER), exercises operational control over Army forces, as delegated by the Commander, U.S. Cyber Command and is the primary headquarters responsible for conducting cyberspace operations (offensive cyberspace operations, defensive cyberspace operations, and Department of Defense Information Network operations), as directed and authorized on behalf of the Commander, U.S. Cyber Command (USCYBERCOM).  ARCYBER organizes, trains, educates, mans, equips, funds, administers, deploys, and sustains Army cyber forces to conduct cyberspace operations.


The Army, foreseeing the increasing global scope of the cyberspace mission, determined it needed an organization solely focused on cyberspace operations. The decision went into the Army Campaign Plan decision point process with the designation, Decision Point 141, and received approval from the Vice Chief of Staff of the Army and the Under Secretary of the Army on 22 December 2009. The Army Chief of Staff approved the decision on 1 February 2010, and directed the establishment of a new separate command with operations centered at Fort Belvoir, Virginia.

A Headquarters, Department of the Army G-3/5/7 Execute Order (No. 155-10), released on 11 May 2010, directed Army Forces Cyber (ARFORCYBER)’s establishment as a separate command. The command was to achieve initial operational capability by 29 June 2010 and full operational capability by 1 October 2010. It was to establish the Army Cyberspace Operations and Integration Center (ACOIC) at Fort Belvoir no later than the 3rd Quarter of FY 2010 and assume operational control of  Network Enterprise Technology Command (NETCOM)/9th Signal Command (Army) and Intelligence and Signal Command (INSCOM) for cyberspace operations, and operational control of several 1st Information Operations (IO) Command (Land) elements.
