rial. Each individual was thoroughly indoctrinated on the subject, and viola- tions were limited to four in TU-2 and eleven in TU-3 The majority of vi- olations resulted from misinterpretations about storage facilities in Hawaii. Security Briefings. Security briefings held during past operations by TG 7.2 for all TG 7.1 personnel arriving in the EPG were eliminated at the insistence of CTG 7.1. The individual background of experience in stringent security environments at all operating locations in the United States and the Security Indoctrination letter were considered adequate. In March 1958 the baggage search for all officers and officer-grade civilians was also eliminated except for spot checks. A certificate was substituted. Security Posters. Prior to Hardtack security posters were requested from JTF 7 by TG 7.1. These were placed at advantageous locations throughout sites and buildings utilized by TG 7.1. However, the system did not appear to be entirely satisfactory, and could be improved by giving this responsibility to TG 7.2 for Eniwetok Island, and to TG 7.5 for other locations. Security Violations. Security violations were quite minor to the over-~ all effort, the most serious having been safe files left open. Violation Hq.

Except at the beginning of Operation Hardtack, however, there were not many problems for the Classification Office, which indicated that the guide was adequate and most personnel knew how to useit. Because of the reduced need for the services of classification people, it is suggested that on the next operation one person can handle both 7.1 and JTF 7 headquarters responsibilities. There was very little in the present guide to find fault with. It is suggested, however, that operation plans (stating shot time) for the shots be permitted to be issued as unclassified at least 2 weeks before the shot instead of the present 3 days. There is nothing magic about 3 days, and from an Operation point of view, 2 weeks is logical provided there is no other reason to classify the information. Also, it is suggested that a genera] classification policy be accepted that what is visible to the general population of an atoll be considered unclassified. 3.16 TECHNICAL REPORTS Annex E to the Task Group 7.1 Administrative Order delineated the procedures and responsibilities for formal reporting of the experimental work of the scientific programs. Briefly, Task Unit Commanders are responsible for seeing that reports are prepared within a reasonable time, that they are technically competent, that they are reviewed for classification considerations, 108
