After more than two decades at the forefront of cyber warfare and psychological operations, the U.S. Army’s 1st Information Operations Command (1st IO) has officially been deactivated.

The command, which served as the Army’s sole active-duty information operations unit, ceased operations in May 2025, marking the end of a 23-year run shaped by evolving digital threats and shifting strategic priorities.

The closure comes as part of the Army’s broader Force Structure Transformation initiative, a sweeping overhaul aimed at streamlining capabilities and better integrating new technologies across the force.

Originally established in 2002 and based out of Fort Belvoir, Virginia, 1st IO operated under U.S. Army Cyber Command and played a critical role in information warfare by defending against enemy propaganda, simulating cyberattacks through “red teams,” and bolstering cyber readiness across units.

“For more than two decades, the soldiers and leaders of 1st IO have been at the forefront of information warfare, adapting to every challenge and shaping the Army’s cyber capabilities,” said Lt. Gen. Maria Barrett, commanding general of U.S. Army Cyber Command, in a May 8 Army news release.

“Their contributions have been instrumental in securing our nation’s interests in an ever-changing battlefield.”

While the decision to shutter the command may appear to signal a step back from information operations, Army leadership has stressed that the move reflects a pivot—integrating such capabilities more directly into field units and joint operations, rather than isolating them within a single command.

This strategic consolidation aligns with broader Department of War reforms. In late April, Secretary of War Pete Hegseth issued a directive titled “Army Transformation and Acquisition Reform,” which called for major structural changes across the military.

Among the key reforms outlined in the memo were increased deployment of unmanned aerial systems (drones) and the deeper embedding of electronic warfare into maneuver units. These shifts fall in line with some of the duties previously carried out by 1st IO.

Despite its wide scope, 1st IO at times found itself overstretched. Its director of information warfare said last year that the unit was often tasked with responsibilities that, while technically within its domain, were not “truly related” to its core mission.

This lack of specialization contributed to the decision to disband and redistribute functions among new, more focused units.

1st IO’s origin lies in the Army’s recognition of cyberspace as a new domain of warfare.

It was the successor to the Land Information Warfare Activity, created in the 1990s in response to lessons learned during the Gulf War.

With the onset of post-9/11 conflicts, 1st IO became an essential element in the military’s digital toolbox, deploying field support teams overseas to locations such as Qatar, and serving as a cyber shield against adversaries seeking to exploit U.S. vulnerabilities through non-kinetic means.

The unit's 2006 commander, now-retired Maj. Gen. John Davis, captured the nature of modern warfare in terms that remain relevant today. “Warfare is evolutionary and mutable,” he said.

“Adversaries have spent decades learning from us, exploiting effects under the threshold of armed conflict.”

Davis also coined the memorable phrase describing the battlefield as one composed of “bullets, bombs, bits and bytes,” underscoring the hybrid nature of today’s threats.

In place of the centralized 1st IO model, the Army is rolling out a more distributed approach through the formation of Theater Information Advantage Detachments. These regionally tailored units will focus on information and cyber warfare within specific combatant commands, offering more localized expertise.

They will also coordinate closely with the Army’s emerging Multi-Domain Task Forces, experimental units that integrate traditional combat arms with cyber, space, and electronic warfare elements.

These task forces are already exploring the use of drones, artificial intelligence, and electronic jamming in real-time battlefield conditions.

This transformation reflects a broader shift in the U.S. military’s doctrine: rather than concentrating cyber and information warfare capabilities in one command, the Army now seeks to empower operational units with these tools directly.

The aim is a more agile, adaptable force prepared to engage adversaries across all domains—land, air, sea, space, and cyberspace.

Though 1st IO has been officially deactivated, its legacy remains embedded in the Army’s evolving cyber posture.

As threats continue to grow in complexity, the contributions of the unit’s soldiers and leaders—who served on the digital frontlines for over two decades—will not be forgotten.
