The 229th Aviation Battalion (Assault Helicopter) took part in the Vietnam War and remained behind when the 11th Aviation Group departed with the bulk of the division, providing support to the 3d Brigade, 1st Cavalry Division (Airmobile) at Bien Hoa in June 1971.

It was reactivated on 21 September 1978 at Fort Campbell, Kentucky, as an element of the 101st Airborne Division (Air Assault).

Concurrent with the redesignation of aviation units to a regimental system, the 229th was inactivated on 16 October 1987 at Fort Campbell, and relieved from assignment to the 101st Airborne Division (Air Assault).

[6] The battalion is now assigned to the 16th Combat Aviation Brigade, Gray Army Airfield at Joint Base Lewis–McChord, Washington.

During Desert Storm the battalion captured 527 enemy combatants, serving with the 101st Airborne Division (Air Assault).

"[11] The unit flew AH-64 Apache attack, OH-58C Kiowa Scout, and UH-60L Black Hawk dedicated SAR helicopters.

[13] Company C, 229th Aviation Battalion was redesignated on 6 January 1992 as Headquarters and Headquarters Company, 3rd Battalion, 229th Aviation, and activated at Fort Hood, Texas (organic elements concurrently constituted and activated) on 10 January 1992 under the command of LTC John E. Pack.

The AVG granted that permission and several of the original Flying Tigers, including David "Tex" Hill, John Richard "Dick" Rossi and Ed Rector attended the unit activation at Hood AAF in June 1988 (along with a CAF P-40 that landed at Hood AAF for the ceremony).

The Battalion flew two night "Deep Attack" missions on 26–27 February 1991 and spent time at As Salman AB and along with the French forces, patrolled the westernmost portion of the coalition flank, including up to the Euphrates River to ensure Iraqi forces abided by the agreed upon cease fire terms.

In 1999 the Battalion was ordered to Active Duty in support of NATO SFOR in Bosnia-Herzegovina, stationed at Comanche Base, BiH.

It was again ordered into active military service on 6 June 2004 in support of Operation Iraqi Freedom, released on 28 December 2005 and reverted to reserve status.

In April 2019 the battalion deployed to Camp Buehring, Kuwait in  support of Operations Spartan Shield and Inherent Resolve.
