The 189th Infantry Brigade is an Infantry brigade of the United States Army based at Joint Base Lewis-McChord, Washington. It is a training brigade subordinate to First Army. Originally organized as a part of the 95th Infantry Division for World War I, the brigade never saw combat in that conflict. Kept active and in the reserve through much of the 20th century, the brigade in name was reorganized into a different unit for fighting during World War II. Seeing numerous moves, activations and deactivations, the brigade has been used principally as a training unit for most of its existence. Reactivated again in 2006, the brigade is now primarily responsible for training provincial reconstruction teams and their supporting elements for deployment to the War in Afghanistan.
