U.S. Army
Cyber Corps
The newest branch in the Army — fighting in cyberspace, the fifth domain of warfare. From offensive operations against nation-state networks to defending the Army's global network to tactical cyber teams with brigade combat teams, the Cyber Corps exists because the next war will be fought in networks before it's fought on the ground. Every weapon system, every command network, every logistics database is a cyber target.

Cyber's roots trace through the Signal Corps and electronic warfare. The Army has been fighting in the electromagnetic spectrum since WWII — jamming enemy radios, intercepting communications, and protecting friendly networks. As warfare moved from radio to computer networks, the mission outgrew the Signal Corps. U.S. Cyber Command stood up in 2009. The Army established the Cyber branch in 2014 — the first new branch since Special Forces in 1987 — because cyberspace had become a domain where wars could be won or lost before the first shot was fired.

FINANCIAL CYBER OPS
The Army's cyber adversaries are the most capable intelligence services and militaries in the world. Russia launched NotPetya — the most destructive cyberattack in history — and penetrated U.S. networks through SolarWinds. China conducts industrial-scale intellectual property theft and espionage. Iran has launched destructive attacks against critical infrastructure. North Korea funds its weapons programs through cyber theft. Army Cyber operates under the doctrine of persistent engagement — maintaining constant contact with adversaries in cyberspace rather than waiting for an attack.

DEFENSIVE CYBER OPS
Army Cyber Command — ARCYBER — is the Army's operational cyber headquarters, commanding all Army cyber forces. Based at Fort Eisenhower, Georgia, ARCYBER conducts offensive cyber operations, defends the Army's global network (DoDIN-A), and provides cyber effects to combatant commanders. ARCYBER provides Cyber Mission Force teams to U.S. Cyber Command for national-level operations. The command operates 24/7 because cyberspace never sleeps and nation-state adversaries don't take weekends off.

The Cyber Mission Force is organized into specialized teams. Cyber Protection Teams defend Army and DoD networks. Combat Mission Teams conduct offensive operations against adversary targets in support of combatant commands. National Mission Teams defend the nation against strategic cyber threats. The Army provides a significant portion of the 133 CMF teams across the joint force. Each team is a small, highly skilled unit — the cyber equivalent of a Special Forces ODA. Small teams, high impact, strategic effect.

Cyber isn't just a strategic capability — it's being pushed down to the tactical level. Expeditionary Cyber Teams deploy with brigade combat teams to provide organic cyber and electronic warfare effects on the battlefield. Cyber-Electromagnetic Activities integrates cyber, EW, and spectrum operations at the division level. The Army is building a force where every BCT has cyber capability — the ability to jam enemy communications, exploit their networks, and protect friendly systems at the point of contact.
