ENCLOSURE "A" (Continued)

        Ships of this Task Group have not had a full delivery of personal mail since 6 March 1945. In view of the fact that personal mail is not a vital consideration in the prosecution of war, it remains a very important morale factor, and as such, its delivery should be expedited to ships of all types.

PART VI (C) - COMBAT INFORMATION CENTER

    1. CIC aboard these ships was used primarily for three (3) purposes:
              (a) Positioning of the ship for firing rockets,
              (b) surface search to detect enemy activates,
              (c) Navigation.

    2.      (a) Tracking consisted chiefly of the detection of small suicide boats by means of radar and attacking then using radar ranges and bearings in determining course to steer.
             (b) Surface search was employed to detect enemy activity, including snail boats and swimmers as were as an aid in station keeping on patrol duty.
             (c) Fire control was performed by the use of radar ranges in conjunction with visual fixes. The SU-1 radar has exceptionally fine target discrimination and was useful in determining firing point for rocket runs.
             (d) Shore bombardment was used extensively during night patrols to harass the enemy beaches and prevent enemy work on beaches. Radar ranges and bearings were useful in this assignment.

    3. Special radar operations techniques: Several ships found it advisable during, patrol when enemy activity was likely to assign two operators to the radar set. One operator watched the A scope and the other watched PPI. This procedure assured that all targets were promptly seen and reported.

    4. IFF performance The usual IFF limitations were encountered. The most prominent one being the non-directional characteristic of our BN radiations.

    5. Maintenance of radar In this group radar maintenance was necessarily undertaken by the operators of the various ships. In many cases ships' company have made repairs to their own equipment, and when this was not possible technicians were available from the staff personnel. By this method some ships had to sail without their radars in operation, but this seems necessary until some trained technicians are available. Instances of this type were few, however, due to the fact that the staff radar technicians, although hampered by limited time and facilities, performed their duties to the greatest possible extent and to the complete satisfaction of this Command.

    6. CIC communications was handled internally by means of inner communications system to CIC, conn and radio room.
