made to provide for frequent rotation of personnel at all levels to home laboratories or stations, or that a marked and extensive improvement be made in living and recreational facilities at EPG. J-1 Section, Personnel and Administration. Security — The Joint Se- curity Indoctrination Letter for Task Groups 7.1 and 7.5 was issued on December 23, 1957, for Hardtack. It is strongly recommended that such a document, as well as other security procedures, be issued no later than Septembes<%*of the year preceding a spring operation to allow time for dis~- tribution and use of the letter before personnel depart for overseas. As in previous operations, many military personnel assigned to Task Group 7.1 reported for duty without security clearances. Since these per- sons could not begin work without clearance, many man-days were wasted, and the over-all effort was retarded. Only personnel with current Secret or Top Secret military clearances should be assigned to TG 7.1. For Redwing and Hardtack, the TG 7.1 Military Executive performed additional duty as Security Officer. It is recommended that a full-time Security Officer be assigned for future operations, preferably a civilian with experience in AEC security procedures. CINCPAC Serial 020 continued to create confusion, delay, and irritation. It is strongly recommended that the need for this directive be reviewed on at least two counts: (1) Since TG 7.1 personnel have either military or AEC clearances before being ordered to EPG, it seems redundant to declare them "good security risks," and (2) the list of contraband items should be reviewed and either eliminated, or shortened and clarified. *V- Transportation - MATS performed its primary mission of moving per- sonnel and cargo in a satisfactory manner. However, aborts and late departures of C-97 aircraft continued during Hardtack to the extent that the MATS flight to and from EPG was regarded by a number of people as the worst feature of the tour of duty. The use of C-118's during the later phases considerably alleviated this problem. It is recommended that efforts continue toward improving the convenience and reliability of MATS transportation. The inter-atoll transportation by C-54 aircraft was an improvement over past operations and was appreciated by all personnel. Morale - In general the small camps on shot islands were adequate in size and space was available upon arrival of personnel. The base camps on Eniwetok and Parry Islands, however, were inadequate in most respects. On Parry, quarters were still being constructed on a crash basis when the population neared its peak, and it was necessary to move some personnel several times as new buildings became available. It is again recommended that camp construction be accomplished between operations when it can be done conveniently and economically. Other facilities on Parry, such as the mess hall, camp store, and movie theatre, were also inadequate. All such facilities, which are important to comfort and morale, should be designed and constructed to take care of the operational population before another test series is undertaken. The amateur radio station at EPG improved morale by facilitating frequent and inexpensive conversations between persons at Eniwetok and their families and friends in the United States. Although widespread use of radio- telephone for pergonal conversations presents a certain security hazard, ex- pansion of amateur radio service at EPG should be encouraged for its obvi- ous effect on morale. Instructions covering amateur station licensing, etc., similar to JTF 7 SCI 10-13, should be published several months prior to the 115
