FORT MCPHERSON, Ga. -- Soldiers from the U.S. Army Center for Health Promotion and Preventive Medicine-South (USACHPPM-South) cased their colors during a ceremony held Oct. 29 at Fort McPherson. Although the unit\'s Fort McPherson worksite will remain open and continue to provide regional support until Sept. 30, 2009, this ceremony acknowledges the unit's pending re-location to Fort Sam Houston, Texas. The unit is currently conducting split-based operations at both sites, with the majority of personnel already in Texas. USACHPPM-South has existed under several names and with different preventive medicine support capabilities at Fort McPherson. In the 1960s it was known as the Army Medical Laboratory, Fort McPherson. In 1974, the Army medical laboratories were redesignated as Army Environmental Hygiene Agency (AEHA) regional divisions. In August 1985, the commanders were redesignated as lieutenant colonel command-select positions and the units were renamed field support activities, with USACHPPM-South designated as AEHA-Field Support Activity South. Finally, in December 1995, it received its current name. The size and composition of the future USACHPPM-South continues to undergo revision with the addition of new capabilities, including an enhanced public health surveillance laboratory.
