Additionally, messages originated by an unidentified entity associated with the 34th Division have also been passed by Station ECHO as late as 15 December indicating that this entity was located in the area of 16-42N 106-19E (XD 425467).

Messages originated by Hq, 32fth Division have also been passed by Station ECHO indicating that at least an element of the division headquarters has been located east of Tchepone.

Laos SIGINT has been unable to contact its DRV communications between Hq, 320th Division since 8 November. Communications between the garrison and an element of Hq, the Military Region 3 headquarters, possibly left behind in the area, ceased to be observed on 18 November.

Messages from Hq, Military Region 3 North have indicated that suspect infantry regiment subordinates of the 320th Division are moving south. Messages from Hq, Military Region 3 North have also been passed by Station CHARLIE as late as 18 December.

In summary, the communications which have reflected the deploying elements of the 34th and 320th Divisions include: communications with its subordinates; the broadcast group controlled from High Command serving the Hq, PAVN 304th Division in communications with its subordinates; one group sporadically serving the Hq, PAVN 304th Division; the broadcast group controlled from High Command serving the Hq, PAVN 320th Division in communications with its subordinates; one group infiltrating into South Vietnam.

The locations of the deploying elements of the two divisions and the five way stations are depicted on a map included in the hard copy follow-up report.

# SITUATION SUMMARY

The eastern Quang Nam Province has been identified as serving in South Vietnam's Military Region (MR) 5, a radio station.

In South Vietnam, contacts with Allied forces have been reflected in the 2nd Battalion, 2nd Regiment PAVN 368B Artillery Regiment, while serving Communist units in Quang Tin Province.

Results of Communist attacks and preparations for further offensive activity were discussed by military intelligence elements from the Military Intelligence Bureau of COSVN in western Kontum Province on 28 January.

In MR 1, a message on 28 January discussed probable Allied units located in the Tay Ninh-Binh Long Province border area.

In the area northwest of Khe Sanh in Laos, the major PAVN headquarters has been identified as the Khe Sanh Area Front headquarters, serving as the senior authority over PAVN Forces in the Laotian border area.

On 31 January, SIGINT indicated that Vinh Airfield probably would resume operational status within the next several days. Laborers were reportedly repairing the airfield and still had two craters to fill.

# PAVN Rear Services

United States forces was noted the probable reflection of the halt to the Tet truce by an unidentified PAVN Rear Services element and Company 10 in 30 January. This message from an unidentified PAVN Rear Services element and Company 10 addressed to the PAVN 93th Transport Battalion Rear disclosed that "the enemy is cheating in regard to the order for a cease-fire." The message further revealed precautions against enemy airstrikes and any convoys whose operations would extend into air strikes.

In addition, in daylight hours were probably required to take precautions against enemy fog, rain, or cloud cover. Also on 30 January, a message was sent to warehouse/storage areas advising them to take positive steps to camouflage the roads leading to truck parks having cargo, as well as the warehouses.
