Background
If you were a pilot in the air cav and you were killed, you were probably a scout pilot. That’s the way it was. Sometimes, it was a slick pilot. Very rarely a cobra pilot. Usually a scout pilot.
Mills and Anderson, p. 240.
The Kiowa was a small and agile scout/observation helicopter. Introduced in 1969, OH-58As joined divisional reconnaissance squadrons in Vietnam. In visual reconnaissance, a Kiowa flew at tree level or lower, looking for the enemy. If it found them — often by taking fire — the crew called a helicopter gunship orbiting above. If necessary, they then summoned the squadron’s “aero-rifle” platoon to place troops on the ground. Sometimes, they even called in artillery or fixed-wing strikes. In the 1st Cavalry Division (airmobile), the reconnaissance squadron was the 1st Squadron of the 9th Cavalry Regiment. Although it had only about an eighth of the 1st Cav’s fighting forces, the 1/9 accounted for half of the enemy killed by the division.
The ultimate version of the little scout is the OH-58D Kiowa Warrior. By the 1980s, enemy ground fire had become too powerful for up-close-and-personal scouting. The Kiowa Warrior, an OH-58D upgrade introduced in 1991, was built to do armed reconnaissance in hostile environments. Its two-person crew could be armed with an impressive choice of rockets, missiles, and heavy machine guns. Thanks to its mast-mounted-scope, the Kiowa Warrior could shield its fuselage under obstacles, yet look for the enemy day and night. If it discovered them, it could laser designate them as targets for its hellfire missiles.
In 2015, the Army retired its Kiowa fleet. There was no direct replacement. Instead, the Army called back many AH-64 Apache gunships from Army National Guard units to fill the gap.
