1st IO Command Overview

General: Located at Fort Belvoir, Virginia, 1st IO Cmd is the Army’s only Active Duty Information Operations (IO) unit. A multi-component, brigade-level organization, it consists of a Headquarters and Headquarters Detachment (HHD) and two battalions. 1st IO Cmd’s mission is to provide IO support to the Army and other Military Forces through deployable IO support teams; IO planning, analysis, and reachback support; and specialized IO training. 1st IO Cmd is a major subordinate command of the U.S. Army Intelligence and Security Command, and is under the Operational Control (OPCON) of the U.S. Army Cyber Command.

Originating Concept: The origins of 1st IO Cmd are directly tied to Army lessons learned from the 1991 Persian Gulf War regarding the need for an organization to provide Information Warfare/Command and Control Warfare (IW/C2W) support to Army commands.

LIWA: In late 1993 and early 1994 the INSCOM Commander, LTG Paul Menoher, developed the concept of the Land Information Warfare Activity (LIWA) as an internal INSCOM directorate. The directorate, was built "out-of-hide" and consisted of fewer than a dozen personnel. On 8 May 1995, HQDA activated LIWA as an operational Table of Distribution and Allowances (TDA) organization under the Command of USAINSCOM, with the mission to "provide IW/C2W operational support to land component and separate Army commands, AC/RC, to facilitate planning and execution of Information Operations."

1st IO Cmd Activation: On 28 October 2002 - HQDA activated 1st Information Operations Command (Land), assigning the command OPCON to HQDA G3/5/7 through the DAMO-OD, and ADCON to USAINSCOM. Since its inception, the command has endured a wide range of doctrinal and organizational changes. Overall, it has had a dynamic mission and has accordingly maintained itself as an adaptive organization.

OPCON to ARCYBER: On 2 February 2011, HQDA assigned the command OPCON to US Army Cyber Command (ARCC), with USAINSCOM retaining ADCON.

Assigned to Army Cyber Command: Department of the Army General Order 2021-04, dated 3 February 2021, directed the assignment of 1st Information Operations Command from INSCOM to US Army Cyber Command with an effective date of 1 October 2021.
