The then-experimental 1-9 Air Cav ushered in a new era of combat called, air assault.
These teams were composed of aero-weapons (Reds), aero-scout (Whites), and aero-rifle (Blues).
Together, ground (D Troop), and air reconnaissance teams patrolled the Vietnam countryside in search of the enemy.
Once located, the infantry (Blues) would insert (and extract) via helicopter or foot to engage the enemy with support of their aero scouts and aero weapons.
These teams earned the nickname of "Headhunters."
This concept differed from conventional front line warfare typical in prior land warfare.

On December 5, 1970, 9th Air Cavalry Brigade (Provisional) was formed by 1 Cavalry as an ad-hoc brigade and organized by operations order OPORD 1-70 consisting of:
1/9 Cavalry
HQ Troop, A, B, C, D, E,& F Troops
3/17 Cavalry
HQ Troop and A, B & E Troops
The brigade was responsible for 5,976 square miles.

During the Vietnam war, the 1st of the 9th Cavalry earned 3 Presidential Unit citations and 5 Valorous Unit Citations.
It was inactivated on 26 February 1973 and was one of the last conventional units to leave Vietnam.
In 1971, as the 1st Cavalry Division began redeployment to the United States, Troop F, 9th Cavalry was formed from one platoon each from the 1-8 Cavalry, 2-5 Cavalry, 1-12 Cavalry and 1-7 Cavalry.
This unit operated independently of the 1-9 Cavalry.
Troop F was inactivated in Vietnam on 26 February 1973.
