Second Army was most recently located at Fort Belvoir, Virginia as a Direct Reporting Unit to Headquarters U.S. Army, Chief Information Officer (CIO)/G-6.
 Under the CIO/G-6, Second Army served as the single point of contact for Army missions and functions related to reporting on, assessing, planning, coordinating, integrating, synchronizing, directing and conducting Army network operations.

The 9th Army Signal Command is the operational executive agent for Army-wide network operations and security.

Western Defense Command (WDC) was established on 17 March 1941 as the command formation of the U.S. Army responsible for coordinating the defense of the Pacific Coast region of the United States.
 A second major responsibility was the training of soldiers prior to their deployment overseas.
 The first Commanding General of WDC was Lieutenant General John L. DeWitt, who continued on in command of the Fourth U.S. Army.
 WDC headquarters were co-located at the existing Fourth Army headquarters at the Presidio of San Francisco.
 WDC's operational region covered the states of Washington, Oregon, California, Idaho, Montana, Nevada, Utah and Arizona.
 However, until 11 December 1941 the command was little more than a planning agency.
 On that date the Army coast defense, antiaircraft, and fighter assets on the west coast and in Alaska were placed under the command, which until 20 March 1942 was known as the Western Theater of Operations, then reverted to the previous name.
 From 11 December 1941 until 1 November 1943 Alaska Defense Command was controlled through WDC.

 As a first step, the command established the Army Cyber Operations and Integration Center collocating intelligence, operations, and signal staffs, together with a critical targeting function, and bringing a new synergy to Army cyberspace operations.
 To improve the Army’s cyber capabilities the command fielded a World Class Cyber Opposing Force at the National Training Center; developed new doctrinal concepts for Land-Cyber operations; and identified the Army’s capability requirements needed to fully operationalize the cyberspace domain and grow the Army’s cyber force.
