The 21st Cavalry Brigade flew its final mission last month.
The training aviation brigade will inactivate in June.
For 30 years the brigade, currently made up of about 80 soldiers, has conducted Apache helicopter training, and more recently training of foreign military units and unmanned aircraft.
The brigade’s aircraft will be redistributed to other Army combat aviation brigades or sent to receive upgrades to the newer model, said Col. John White, brigade commander.
Other airframes, such as the Black Hawk and Lakota helicopters have already been dispersed.
“We have trained over 80 battalion-sized units,” White said, noting that the brigade has worked with every Apache unit in the active-duty Army and the vast majority of reserve-component attack units.
Under the Foreign Military Training Program, the brigade oversaw the training of allied, foreign military Apache aircrews, including a permanent contingent from the Netherlands that has been at Fort Hood since the late 1990s. Recently, the Dutch program expanded to include a Chinook program and training of army forces from the Netherlands.
Training support to the Netherlands is scheduled to continue under another unit through 2015, according to a Forces command directive. Other brigade missions included mobile assistance training teams, Gray Eagle training support and High-Altitude Mountainous Environmental Training, White said.
Gray Eagle Unmannned Aerial Systems training can now be conducted at a unit’s home station because of the program the brigade helped develop, he added.
