The Washington Army National Guard’s 81st Stryker Brigade Combat Team will be restructured into a Mobile Brigade as part of the U.S. Army’s broader transformation effort, officials confirmed.
The shift reflects a major doctrinal update aimed at increasing speed, agility, and operational flexibility across the force.
In a statement, Brig. Gen. Paul Sellars, commanding general of the Washington Army National Guard, described the move as a turning point for the organization.
“Change isn’t always easy, but this is a big win for us,” he said. “Being chosen to make the shift to a mobile brigade is a testament to our organization and shows just how strong and capable our team is. This is another major milestone for the 81st, and for the entire Washington Army National Guard. It keeps our organization relevant and ready, whether we’re called to help overseas or respond to emergencies here at home.”
The Army’s plan involves replacing the 81st Brigade’s existing fleet of eight-wheeled Stryker armored vehicles with lighter and more mobile infantry squad vehicles (ISVs). The transition will also introduce new unmanned aerial systems and supporting technologies, in line with the Army’s modernization goals.
An infantry battalion from the Utah National Guard will be integrated into the newly reconfigured 81st Mobile Brigade. Earlier this week, leaders from Utah joined the Washington command in preliminary discussions about the transition.
“As we’ve learned before, transformations like these take a lot of time and patience,” Sellars said. “It’s nice to have a partner to go through this process with. We look forward to working with Utah and welcome their men and women to the 81st Brigade.”
The brigade is scheduled to begin returning its Stryker vehicles in October 2025, a process that is expected to take several months. The change is not only logistical but also operational, with training, personnel structure, and deployment strategies all subject to reevaluation under the new model.
This is the second major restructuring for the 81st Brigade in a decade. In 2015, the unit transitioned from an Armored Brigade Combat Team equipped with main battle tanks to a Stryker Brigade Combat Team. That shift reflected an earlier Army directive aimed at improving deployability without sacrificing combat capability.
The broader modernization framework, known as the Army Transformation Initiative, was announced in May 2025. The initiative seeks to convert existing Infantry and Stryker Brigade Combat Teams into Mobile Brigade Combat Teams with improved speed, deployability, and lethality in contested environments.
The 81st’s new role underscores the Army’s view that future conflict will require rapid maneuver forces equipped with lighter, adaptive technologies. By moving away from heavier platforms like the Stryker, the Mobile Brigades are expected to respond more quickly to emerging threats while leveraging integrated drone support and decentralized mission profiles.
As the Army presses ahead with its modernization plans under the leadership of President Donald Trump’s administration, the 81st’s transition is expected to serve as a test case for the future structure of National Guard units nationwide.
