The 81st Stryker Brigade Combat Team is a modular brigade of the United States Army National Guard based in Washington, Oregon and California. On 9 July 2015 it was announced that the 81st Brigade would convert from being an Armored BCT to a Stryker BCT. In September 2016 the 81st Brigade began the transition to a Stryker Brigade Combat Team. From 2016 to 2021, the 81st Brigade was part of the 7th Infantry Division and wore the ‘Indianhead’ patch under the Associated Unit Program (AUP). However, with the end of the AUP, the brigade donned its original "Raven" patch again in September 2021. As of 2022, the 81st SBCT has changed its alignment from the 7th Infantry Division to the 36th Infantry Division.
