The Navy NTPR is responsible for tracking the largest group of test par- ticipants, 52 percent of the total number reported by the armed services (4). It has identified 106,942 Navy personnel, believed to be virtually all of its participants (5). In addition, the Navy claims about one-third of the approx- imately 50,000 File A personnel (6). The NNTPR has had distinct advantages over the other teams in locating its personnel. Most of the Navy participants, for example, were on ships during the tests, and their exact locations could be identified through use of the ship logs and muster rolls. The NNTPR has access, too, to the fine personnel records system maintained by the Navy. advantages, Making good use of these the NNTPR has been the first team to essentially complete the tasks assigned it by DNA. 28 t
