The operating personnel the Test Aircraft Unit, Test Services The organization structure and the general functional areas of responsitility of each of the three operating units are indicated in Figure l. The Commander of the Task Group was formerly assigned as Deputy Commander of the Air Force Special Weapons Center and, thus, has been associated for some time with the atomic weapons research and development program. On 15 July 957 he was reassigned to the post of Deputy Commander for Overseas Tests in preparation for his subsequent assumption of command of the Task Group. This arrangement made it possitle for him to participate in the field phase of Operation PLUMELCB, the 1957 atomic test series conducted in Nevada. He as- sumed command of the 950th Test Group and Task Group 7.4 on 1 October 1957. The former commander of the 950th Test Group became his deputy, a move which served to insure the continuity of that unit's operations. With the activation of Task Group 7. on 1 October 1957, the varicus staff officers of the 4950th Test Group assumed like staff positions within Task Group 7.4, an arrangement which proved particularly effective. In the case of two officers making up the Commander's special staff it was necessary to request manning from resources other than that of the Air Force Special Weapons Center. The services of a Flight Surgeon with experience in the bio- logical effects of radiation was obtained by arrangement with Headquarters Joint Force SEVEN and Headquarters United States Air Force. 17 COPIED/n0 LANL Re . /7
