The civilian task groups have acquired a good nucleus of well trained and experienced engineers and operators but for many reasons normal Service requisition methods do not provide personnel with adequate experience for the PPG operations. Eariy and aggressive action at the Departmental level of each Service is necessary to insure that adequateiy trained personnel will be available in time to permit shipment of all personnel to the PPG prior to the operation for training. Personnel problems are especiaily apparent in TG 7.2. Increasing operational requirements demand a certain degree of flexibility in the organizational structure but because of the long time requir- ed to alter the table of distribution, it is difficult to satisfy new requirements immediately.
