From 1997, the 166th Aviation Brigade has trained other aviation units for front-line service. As such, it has never seen combat, and has thus never earned any campaign streamers or unit awards. As the only brigade in the First Army responsible for training aviation units, the 166th Aviation Brigade is the principal unit for training Army Reserve and Army National Guard assets preparing to deploy to contingencies around the world, which means it is responsible for 47 percent of all Army Aviation assets.
