fied personnel who will be available for TDY with the Task Force when the need arises. Welletrained personnel are of paramount importance to the Task Force communications mission. The short tour of duty (one year) for garrison force personnel precludes the assignment of unskilled or semi-skilled men for they will require training befcre they may be profitably employed. If a training program is carried on it means that; (1) competent men whose services are needed elsewhere will be required as instructors, and (2) by the time a man is comp- etent to perform his duties little time remains before he is eligible for rotation. This is a difficult problem to resolve since the pipeline replacement personnel have received only basic training and primarily consist of men in the grades of E-2 and E-3. In order to remedy this for Operation CASTLE arrangements were made with G1, D/A, and OCSigO to provide men from special levies placed on ZI communications installations under the control of OCSig0O. Some shortages still existed, however, and these were filled with TDY personnel from both the ZI and USARPAC during Operation CASTLE. C. Eauipment and Facilities. In construction of facilities ard procurement of equipment, planning must begin well in advance of the operational period. Ail major equipment and construction requirements must be firm by at least 90~- 120 days prior to the commencement of on=3ite operations for it takes this long as a lead time for delivery of equipment and as a construction period for facilities. Any requirements submitted after that time will have to ccmpete with the high priority needs <03
