It was originally estimated that 8,000 badges would be required for REDWING; however, since difficulty was encoun- tered in obtaining information for badging other task group personnel, often necessitating that duplicate badges be prepared, a total of 12,783 was issued. The Pass and Badge Office was operated in accordance with procedures established by the AEC Security Office of ALOO. INFORMATION SECURITY. The scope of H&N activities during Operation REDWING, the number of personnel requiring access to classified information, and the necessity of transferring a voluminous amount of classified documents between the various departments within the Home Office and between the Home Office and the PPG called for controlled procedures and practices. In December 1954, the H&N Security Procedures Manual was published, which covered basic security matters relative to safeguarding classified information, instructions for classifying documents, changes ofclassification, preparation for transmission and the accountability production, storage, and distribution of classified documents. Joint Task Force SEVEN Standard Operating Procedure 205-2, issued on 1 February CHAPTER III, SECTIONS 7 and 8 1956, pertained to security education and required that indoctrination letters be read and followed by an examination. One letter was pre- pared for key personnel in supervisory positions or above and one for lower echelon employees. The men who took security examinations during Operation CASTLE were exempt from the examination but required to sign a certificate of compliance; all others were given a written examination based on the test of the indoctrination letters. Notations were made in all H&N personnel records to reflect that an examination had been taken or a certificate of compliance signed. A log of security activities was inaugurated on 18 October 1955, in accordance with a directive issued by CJTF-7. This log was maintained on a weekly basis and served as a chronological history of all security activities. All employees terminating in the Home Office were given a lecture and required to execute a security termination statement, Form AEC-136, which included certain provisions of the Atomic Energy Act of 1954 and U.S. Code Title 18. Jobsite employees were given a termination security lecture prior to their departure from the Proving Ground and were also required to sign Form AEC-136. Upon arrival at their places of hire-whether it was Honolulu, San Francisco or Los Angeleseach terminating employee was again given a security lecture and required to sign Form AEC-136. He was reminded at this time of his responsibility to notify the Atomic Energy Commission of any anticipated foreign travel. SECTION 8 COMMUNICATIONS The tasks assigned to Holmes & Narver for Operation REDWINGincluded the responsibility for all communications of TG 7.1 and TG 7.5 and the interatoll communications service for the Task Force. This was considerable expansion in functional responsibilities over that of previous Operations at the Proving Ground and led to the establishment of a Communications Department within the Contractor's Administration Division. During the peak of the Operation, 30 teletype operators were required to cover all channels. These men, with a relatively short period of on-the-job indoctrin- ation, were readily able to adapt themselves to the procedures involved. In general, a high quality service was provided, with errors and security violations being very few. Indoctrination of personnel was facilitated by the issuance of a Communication Operation and Instruction Plan. This plan covered the communication system capabilities and the standard procedures which outlined definite practices and methods for the in-station handling of messages. Particular emphasis was placed on security, accuracy and speed-of-message handling. Page 3-45
