The famous Bird Dog was what the Army used when Cliff finished his fixed wing training.
Hueys were used extensively in Viet Nam. Cliff flew them for a short time after he arrived in Viet Nam and then transitioned into the LOH (low observation helicopter).
He trained in the Cobra below, but never flew them in Viet Nam.
This OH 13 Bell helicopter was used for the first phase of rotary training.
During the last 9 months (of the year to the day) Cliff was in Nam he flew the LOH below.
