My dad was in a Marine helicopter squadron (Evil Eyes HMM-163) based at times in Phu Bai, Vietnam (adjacent to the formal imperial city of Hue). He talked about it maybe once.
I found out later that his squadron was in the thick of the DMZ and supported both Marines and Green Beret teams. Little did I know he had received numerous air medals and commendations (he didn't want to glorify war).
His squadron helped rescue the 5th Special Forces Group from enemy capture in the Battle of A Shua Valley in March 1966 when their camp was being overrun (10 Green Berets and approx. 400 ARVN versus 2,000 NVA). The squadron flew over 2,000 flight hours in ten days during the battle in which 190 survivors were rescued in the face of heavy enemy anti-aircraft fire. During the battle, 21 of the 24 aircraft assigned to the squadron suffered "major damage" including the two that were shot down.
I JUST returned from a trip to Vietnam over the past 2 weeks. I visited the former bases where my father was stationed (Phu Bai and Da Nang) as well as other cities. I kept wondering what it must have been like for all those young men. The Vietnamese people were extremely friendly and gracious and thankful to be living in peacetime.
