United States Army Cyber Command. It is a subordinate unified command of the United States Cyber Command and a component of the United States Army Forces Command. Established in 2009, its headquarters is located at Fort Eisenhower in Georgia. The command is responsible for conducting cyberwarfare operations, defending the Department of Defense Information Network, and providing support to combantant commands worldwide.

History

The command was established in 2009 as a provisional organization, recognizing the growing importance of the cyber domain in modern warfare. Its initial headquarters was at Fort Belvoir in Virginia. In 2014, it achieved full operational capability and was officially designated a subordinate unified command under United States Cyber Command. A significant reorganization occurred in 2018, merging the command with the Second United States Army to better integrate cyber operations with electronic warfare and information operations. The command's headquarters relocated to Fort Gordon (now Fort Eisenhower) in 2020, co-locating with the United States Army Cyber Center of Excellence and the National Security Agency's Georgia Cryptologic Center.

Mission and responsibilities

Its primary mission is to conduct full-spectrum cyber operations to ensure United States Army freedom of action in cyberspace and deny the same to adversaries. Core responsibilities include directing and conducting offensive cyber operations and defensive cyber operations. The command defends the Department of Defense Information Network and critical Army networks against persistent threats. It also provides trained and ready cyber forces to support geographic combatant commands like United States Central Command and United States Indo-Pacific Command, as well as functional combatant commands such as United States Special Operations Command. Furthermore, it integrates cyber capabilities with electronic warfare and information operations to support multi-domain operations.

Organization

The command is led by a lieutenant general who also serves as the commander of the Second United States Army. Its main operational component is the Joint Force Headquarters – Department of Defense Information Network, which directs the global defense of the Department of Defense Information Network. The principal warfighting formation is the 780th Military Intelligence Brigade (Cyber), headquartered at Fort Meade in Maryland. Other key subordinate units include the Cyber Protection Brigade, which focuses on network defense, and the 1st Information Operations Command (Land), which integrates information-related capabilities. The command works closely with the United States Army Cyber Center of Excellence for doctrine development and force training.

Operations and activities

The command conducts continuous operations to protect Department of Defense networks from threats posed by state actors like China and Russia, as well as non-state actors. It supports named operations such as Operation Inherent Resolve and Operation Atlantic Resolve with tailored cyber effects. Activities include hunting for advanced persistent threats, conducting vulnerability assessments, and executing cyber mission force team deployments globally. The command also participates in major exercises like Cyber Flag and Cyber Blitz to test tactics and interoperability with allies including the United Kingdom's National Cyber Force and NATO cyber units.
