My understanding is the 623rd Quartermaster Company (AER&S) is a member Quartermaster Corps' *Distinguished Unit of the Regiment*. Induction date unknown. No photo or award scan is available.
The 623rd shared facilities of the 109th Quartermaster Company at Cam Ranh Bay. The 623rd's mission was to offer Depot support for supply and field maintenance, and reclamation of air delivery equipment. The 623rd made major contributions in Junction City, Khe Sanh, and A Shau Valley.
The 109th, 383rd, and 623rd all played a major role in the airdrops
delivering over 8,000 tons of supplies by parachute and extraction systems
that set a record of most tonnage ever drop into *actual combat* for a
30 day period during Khe Sanh and TET68. A record still holds to this
