The DOD requirements for nuclear weapons were apparently fo the AEC weapons laboratories through the Military Liaison Commi Figure 11). The AEC laboratories then designed the devices tha tested at the appropriate proving ground, either the NPG or the special location of the PPG required a miltary operation to con tests. The JTF 7 Scientific Director actually directed the tes CJTF 7 enforced his decisions. The joint task force was divided] into functional and service-branch oriented units, each of which repofted to CUOTF 7 through separate task group commanders. Task Group 7.1 (Scientific) TG 7.1 was the centerpiece of the operation. It contained rq@presenta- tives of the organizations providing the devices and the represegtatives of the DOD laboratory organizations interested in the effects of{the devices. All the other groups at the PPG were there to assist TG 4.1. [TG 7.1 was primarily led by LASL. The newer laboratory, UCRIJ, did provide one test device in CASTLE and a large contingent of persdmnel, but most of the key positions in TG 7.1 were held by LASL personnel. There waS a "Deputy for UCRL,”™ a position that recognized both the new Babora- tory and its junior position. The task group was organized into fask units with special functions. There were 12 task units, but they] were designated 1 through 15, with no task units corresponding to 5, 19, and ll. TASK UNIT 1 -~ LASL PROGRAMS. The function of this unit was diagnostic measurements of the LASL-designed nuclear devices. DO fo make person- nel did participate to a certain extent in this task unit, as furffher discussed in Chapter 3. TU 1 personnel totaled about 145. 55
