with headquarters in Nha Trang and the 68th Medical Group responsible for medical care in III and IV CTZ with headquarters at Long Binh. Dental, veterinary, laboratory and preventive medicine units and the medical depot came under direct operational control of the 44th Medical Brigade Headquarters. The arrival of the 522d Medical Detachment (Team AF) (Veterinary Professional Services) in March 1968 provided one command and control element for all brigade veterinary units. With the arrival of the 172d Preventive Medicine Unit in June 1968 the command structure was changed to include two preventive medicine units under direct operational control of the brigade headquarters. The only other major subordinate unit to relocate during 1968 was the 9th Medical Laboratory which moved from Saigon to Long Binh in November. At the end of 1968 the 44th Medical Brigade was composed of 169 units. Of those, 42 arrived in-country during 1968.

The sponsoring unit was required to prepare a plan for support for the incoming unit to include arrival of their advance party, main body, and unit equipment. Because of the emphasis given to detailed advanced planning and command interest, effective coordination was accomplished and units arriving in-country were fully integrated into the brigade and ongoing operations with minimal delay.
