Approved For Release 2006/03/06 : CIA-RDP78T02095R000700080091-8 COMMUNIST VIOLATIONS OF THE 27 JANUARY VIETNAM AGREEMENT Approved For Release 2006/03/06 : CIA-RDP78T02095R0007000800W6Rl Approved For Release 2006/03/06 : CIA-RDP78T02095R000700080091-8 COMMUNIST VIOLATIONS OF THE 27 JANUARY VIETNAM AGREEMENT Listed below are the major Communist actions which can be described as violations of the 27 Jan- uary "Agreement on Ending the War and Restoring Peace in Vietnam." Each of these Communist actions is listed under the specific Article of the 27 Jan- uary Agreement with whose provision it is in direct or presumptive conflict. Each is listed and de- scribed only once, under the lowest-numbered Article of the Agreement where the violation fits. For example, Communist infiltration and logistic move- ments through Laos into South Vietnam are listed under Article 7, which forbids the introduction of new troops and military equipment -- except "piece- for-piece" replacement of equipment -- into South Vietnam. We could have listed the same violations again under Article 20, which states that foreign countries shall withdraw all their military forces from Laos and Cambodia. The following account of Communist violations, however, contains no such double counting. ARTICLES of the Agreement ARTICLE 1 This article is not pertinent to Communist violations. ARTICLES 2 and 3 These articles, along with Articles 1-6 of the Cease-Fire Protocol, established the cease- fire in South Vietnam and called for a cessation of attacks against all places under control of the other side.

In South Vietnam, the total number of Communist-initiated cease-fire violations re- ported by the South Vietnamese Armed Forces from 27 January through 9 May are shown below. Major Communist Violations Minor Communist Violations Total 1,924 11,080 MR 1 881 2,921 MR 2 207 1,482 MR 3 326 2,005 MR 4 510 4,672 2. Whatever the absolute numbers, the Communists have clearly committed major viola- tions of the cease-fire in South Vietnam. Just before the cease-fire went into effect, Com- munist forces launched widespread attacks in order to interdict GVN lines of communication and to enlarge areas under their control. Many of these attacks continued beyond the cease-fire -- notably at Sa Huynh on the central coast, in the highlands between Kontum and Pleiku, and in Chuong Thien Province in Approved For Release 2006/03/06 : CIA-RDP78TO2095R000700080091-8 Approved For Release 2006/03/06 : CIA-RDP78TO2095R000700080091-8 the Delta.* After GVN forces had regained most of the territory lost in these attacks, the overall level of fighting subsided. Forces under North Vietnamese command, however, have continued attacking GVN-held positions and towns in order to expand the areas under Com- munist control. The ARVN base at Tonle Cham (Tay Ninh Province) has been under continuous attack for weeks. Communist forces have initiated and are continuing to carry out strong attacks in Hong Ngu District of Kien Phong Province. They have also carried out further attacks in Chuong Thien, Chau Doc, Bac Lieu, and Dinh Tuong Provinces of MR 4. NVA forces have also launched numerous moderate to fairly large attacks by fire and ground probes against GVN positions west of Hue in MR 1. NVA forces have also fired rockets and mortars indiscriminately into many cities, refugee camps, and other population centers -- for example in Tam Chau and Phan Thiet -- causing numerous civilian casualties. They have even mortared the locations of ICCS teams at Tri Ton and Hong Ngu. In the past month the Communists have in- creased their use of terrorism in South Vietnam, including assassinations, tossing grenades in public places, mining of public thoroughfares, and widespread abductions. There have been nearly twice as many assassinations of local GVN offi- cials and supporters, for example, in the * There was also heavy combat in the area north and west of Quang Tri City in the immediate post- cease-fire period, but it is impossible to deter- mine who started each individual action.

Article 3 of the Agreement also states that all military units of both sides in South Vietnam shall remain "in place." In violation of this provision, the 272nd Regiment of the 9th NVA Division is known to have moved in April 1973 from MR 3 and is apparently destined for MR 4, where some elements of the regiment are already reported operating. ARTICLES 4, 5, and 6 These articles are not pertinent to Communist violations. ARTICLE 7 This article, along with Article 7 of the Cease-Fire Protocol, prohibits the introduction into South Vietnam of "troops, military advisers, and military personnel including technical military personnel, armaments, munitions, and war material." It limits equipment inputs to "periodic replacement of armaments, munitions and war material which have been destroyed, damaged, worn out or used up after the cease-fire, on the basis of piece-for--piece, of the same characteristics and properties, under the supervision of the Joint Military Commission of the two South Vietnamese parties and of the Inter- national Commission of Control and Supervision." Communist Violations 1. Summary: Since the 27 January Vietnam Agreement was signed, the North Vietnamese have not used designated entry points for the authorized "replacement" exchange of equipment nor has there been any ICCS supervision of equipment imports. Since 27 January, however, the North Vietnamese have done the following: Approved For Release 2006/03/06 : CIA-RDP78TO2095R000700080091-8 Approved For Release 2006/03/06 : CIA-RDP78TO2095R000700080091-8 Infiltrated over 40,000 personnel into South Vietnam and adjacent border areas of Laos and Cambodia. Moved more than 350 tanks and several hundred field and antiaircraft artillery (AAA) pieces into South Vietnam or adja- cent border areas. Probably moved into South Vietnam at least four regiments (one engineer and three AAA regiments), plus major elements of two armor regiments. The personnel in these units -- some 4,000 men -- are in addition to the 40,000 men who came south in infil- tration groups to flesh. out Communist units already in South Vietnam. Carried on a large-scale and still con- tinuing logistic effort which has moved thousands of tons of military supplies from North Vietnam toward and into South Vietnam. The details of Communist violations of Article 7 are presented below. 2. Personnel Infiltration. In the months following the signing of the Vietnam Agreement, Hanoi continued to dispatch infiltrators from North Vietnam to South Vietnam. as of 6 May, post-cease-fire infil- tration starts have totaled some 16,000 per- sonnel -- about 11,000 regular combat troops and almost 5,000 military and civilian spe- cialists. the rate of infiltration slowed signi- ficantly, and by mid-April it was clear that infiltration of regular combat groups to South Vietnam in the 1972/73 dry sea- son had ended. The infiltration of civil- ian and military specialists has continued Approved For Release 2006/03/06 : CIA-RDP78TO2095R000700080091-8 Approved For Release 2006/03/06 : CIA-RDP78T02095R000700080091-8 at relatively high rates, however, although it too has slowed somewhat since mid-April. virtually all of the personnel w o started the journey south after 27 January have now arrived in South Vietnam. 3. In addition to the 16,000 personnel discussed above, the Communists have also buttressed their manpower position in South Vietnam by allowing 25,000 men who were already in the infiltration system as of 27 January to complete their journey south. Most of these were combat troops. Conse- quently, a total of over 40,000 North Viet- namese regular combat and specially-skilled personnel have arrived in South Vietnam or adjacent border areas since 27 January. 4. Table 1 shows estimated starts of infiltration groups, by week, since 1 Jan- uary 1973. 5. Deployment of Armor and Artillery. Hanoi has made a formidable commitment of firepower to its military forces in South Vietnam during the past dry season, moving southward large quantities of tanks and artillery. While the deployment started prior to the cease-fire in South Vietnam, the majority of these tanks and artillery reached their final destinations after 27 January. Characteristic of this year's commitment is the fact that a greater proportion of this fire- power was deployed farther south, as attested by the large number of tanks and heavy artil- lery noted moving to the southern three-fourths of South Vietnam. This is in marked contrast to a year ago, when the emphasis was on MR 1. 6. Some 600 tanks are conservatively esti- mated to have been sent south by Hanoi since late October 1972, surpassing the number com- mitted to South Vietnam a year earlier for the Communists' 1972 spring offensive.

In addition to armor, Hanoi deployed more than 50 field and antiaircraft artillery groups south this dry season -- about one- third of the total number of regular infiltra- tion groups destined for South Vietnam and Cambodia. The majority of these 50-plus groups completed their southward journey after 27 Jan- uary. In addition to the antiaircraft weapons Approved For Release 2006/03/06 : CIA-RDP78TO2095R000700080091-8 Approved For Release 2006/03/06 : CIA-RDP78T02095R000700080091-8 noted in these infiltration groups, there were several hundred guns belonging to the six inte- gral antiaircraft regiments which have deployed into South Vietnam since early January 1973, three of which arrived after the cease-fire. 8. About 40% of the artillery infiltration groups have been noted with specific types of weapons, including the long-range 122-mm and 130-mm field guns, as well as light to medium antiaircraft weapons. About half of the some 200 heavy field artillery pieces were destined for the lower three-fourths of South Vietnam, and this year for the first time the Communists have deployed 122-mm and 130-mm guns to MR 3 and adjacent border areas of Cambodia. 9. Deployment of Integral Communist Units ommunis s ave pro a ly deployed at least four new regiments -- three AAA and one engineer -- and major elements of two armor regi- ments to South Vietnam in violation of Article 7 of the Agreement. Moreover, other smaller units and elements of COSVN (including elements of the Headquarters of the South Vietnamese Lib- eration Army) also may have been deployed into South Vietnam after 27 January. The personnel in these units are in addition to the more than 40,000 men in infiltration groups. 10. The following list of Communist combat units has been subdivided into two categories, reflecting the degree of confidence we have in our judgment that the redeployment of the unit was in violation of the cease-fire -- i.e., that it moved into South Vietnam after 27 Jan- uary. In Category A we list those units which we are fairly sure moved after 27 January. In Category B, the dates of movement are more open to dispute. Approved For Release 2006/03/06 : CIA-RDP78T02095R000700080091-8 Approved For Release 2006/03/06 : CIA-RDP78TO2095R000700080091-8 Category A The 254th NVA AAA Regiment with some 850 men deployed from North Vietnam to Quang Tri Province, MR 1, in early February 1973. In the period from mid-February to mid- March, major elements of the 593rd NVA AAA Regiment with a strength of 500 men arrived in Kontum Province of MR 2 from southern Laos. In early March the 20th Radar Company of the 290th NVA Reconnaissance Regiment moved from southern Laos to Quang Tri Pro- vince to provide radar acquisition data for the 263rd SAM Regiment, which had de- ployed there from North Vietnam in January prior to the cease-fire. The 3rd Battalion of the 203rd NVA Armor Regiment arrived in Quang Tin Province of southern MR 1 in February with a strength of 200 men and subsequently is believed to have deployed into Quang Ngai Province. During the period 27 January to 17 March, the headquarters of the 203rd NVA Armor Regi- ment was en route to MR 3 and subsequently arrived there in late April. Between 27 January and 20 March the headquarters of the 69th NVA Artillery Command, with a strength of 250 men., moved from a position in southern Kratie Province, Cambodia, to a location in northern Tay Ninh Province, South Vietnam. During March, one battalion of the 239th NVA Engineer Regiment deployed from Laos to MR 2. The remaining two battalions and regimental headquarters deployed to southern South Vietnam during April. The strength of the regiment was about 1,000 men. Approved For Release 2006/03/06 : CIA-RDP78TO2095R000700080091-8 Approved For Release 2006/03/06 : CIA-RDP78T02095R000700080091-8 By April the 245th NVA AAA Regiment -- which had deployed into southern Laos from North Vietnam in mid-January with about 850 men -- had relocated from the Laotian Pan- handle into South Vietnam's Quang Tri Pro- vince. elements of the 201st Armor Regiment had recently arrived in Quang Tri Province and were operating there. The entire regiment has an estimated strength of 1,000 men and some 100 tanks. Category B Beginning in early December 1972 and possibly continuing through mid-February, elements of COSVN (including elements of SVNLA Headquarters) relocated to MR 3 from Cambodia with an unknown number of personnel. Immediately following the cease-fire, elements of the 174th Regiment of the 5th NVA Division and the 207th Regiment possibly reinfiltrated into northern Kien Phong Pro- vince from adjacent areas in Cambodia. 11. The Communist Logistic Effort. North Vietnamese logistic movements across the DMZ and MR 1, and through the Laotian Panhandle toward and into the lower three-quarters of South Vietnam, have continued at a high pace since January -- almost as if there has been no Vietnam Agreement. The major change from previous years is that Hanoi has been able to move its supplies more easily, and in day- light hours, because of the absence of US bombing. 12. The pace of logistic activity observed since the Agreement was signed has fit almost perfectly the pattern of a normal dry season campaign. Activity in the Vinh area, the major transshipment point in North Vietnam for supplies moving south, continued at high levels into early February, and has dropped sharply Approved For Release 2006/03/06 : CIA-RDP78T02095R000700080091-8 Approved For Release 2006/03/06 : CIA-RDP78T02095R000700080091-8 since that time as most supplies have been moved farther south. Activity in the Laotian Panhandle has continued to be heavy right up to the present. Recently, the North Vietnamese have also put a high priority on the movement of supplies from Laos into South Vietnam. NVA vehicle activity has continued within South Vietnam -- at very high levels in Quang Tri Province and at sustained but generally lower levels elsewhere. 13. The movement of military equipment and ammunition has continued throughout the cease- fire period, although in recent weeks there has been an increase in the proportion of total NVA supplies moving which has been identified as foodstuffs and quartermaster supplies. Reli- evidence received since mid-April, however, has indicated that by that time Hanoi already had in storage very large quantities of weapons and ammunition in Quang Tri Province and the Laos/ South Vietnam border area of MR 1. The extremely heavy movement of ammunition south from Vinh which was observed from October 1972 until shortly after the cease-fire would account for the existence of these stocks of military supplies. 14. The Communists have as yet shown no sign of intentions to reduce the level of sup- plies moving southward or the size of their resupply network in southern Laos and South Vietnam. The supply system has been reorganized since the cease-fire to facilitate transporta- tion in an environment free from aerial attacks. Reports received within the last two weeks indi- cate that transportation "offensives" have been initiated by a unit in the southern North Vietnam Panhandle, and by two of the three major logistic groups in southern Laos. These offensives are scheduled to last through May and could be sustained beyond that date depending on the weather. There has also been extensive Communist road construction activity within South Vietnam since the signing of the cease-fire agreement. Although it appears that the North Vietnamese may be develop- Approved For Release 2006/03/06 : CIA-RDP78T02095R000700080091-8 Approved For Release 2006/03/06 : CIA-RDP78T02095R000700080091-8 ing a north-south road network with South Vietnam and extending from the DMZ into MR 3, there has been no evidence that they intend to abandon the Ho Chi Minh trail system in south- ern Laos. a high pace of logistic activity in the North Vietnam Panhandle into southern Laos, and 15. In the following paragraphs we detail the major Communist logistic movements which have taken place since 27 January. For con- venience, we have divided the period since then into three parts: (a) 27 January-28 February, (b) 1-31 March, and (c) 1 April to the present. 16. From 27 January through 28 February, very heavy levels of traffic were observed moving over the passes from North Vietnam south of Dong Hoi. moving on the major routes between NVA logistic entities in the Laotian Panhandle. (See Tables 2 and 3 for a weekly record of NVA truck movements into Laos from North Vietnam and through the Laotian Panhandle.) Similar levels of activity were observed within northern South Vietnam at this time. Hanoi also moved a sub- stantial volume of military supplies into northern Laos during the month of February. there was also heavy traffic A.

On 18 and 24 February, 33 and 30 North Vietnamese cargo trucks, respectively, were traveling this route west of Khe Sanh. The direc- tion of the trucks was not deter- mined. b. A North Vietnamese SA-2 SAM regiment with at least four firing bat- talions moved into the Khe Sanh area of northern South Vietnam in mid-Jan- uary and may have occupied firing posi- tions prior to the cease-fire. The presence of SAMs in this area was first confirmed on 6 February, when two operational sites were detected. Since that date the North Vietnamese have built additional sites. There now are about a dozen sites, and the Com- munists rotate their firing units among these positions to make them less vul- nerable to bombing. At any time, as many as four or five sites may be operational. c. On Route 608 north of Khe Sanh, 32 North Vietnamese cargo trucks were detected on 24 February, and 20 cargo trucks and six unidentified vehicles were seen on 27 February. d. Province from Laos and that base areas for the supplies were being established in the mountains about 25 miles south- west of Hue. as of mid-February, military supplies were continuing to enter Thua Thien e. The North Vietnamese began deploying 130-mm artillery field guns into MR 3 during late February. On 27 February twelve 130-mm field guns reportedly were being towed from Snuol, Cambodia, to Loc Ninh, South Vietnam.

On 6 February, in the western DMZ area, there were 105 North Vietnamese cargo trucks observed on Route 1033A, and 230 cargo vehicles were seen on Route 102B near its intersection with Route 1032A in the same area. g. On Route 102B in the western DMZ, 62 cargo vehicles were detected on 17 February and 59 trucks were observed on 18 February. h. On 1 February there were 23 NVA cargo trucks observed on Route 561A northwest of Quang Tri City. i. On 22 February, 30 trucks were observed entering a North Vietnamese truck park in the western DMZ during a one-hour period. j. A convoy of 18 NVA cargo trucks was moving on Route 102B in the western DMZ on 24 February. B. NVA Logistic Movements in Laos and Cambodia, 27 January-28 February a. During the period 1-10 February, 1,252 North Vietnamese cargo vehicles were active in the tri-border area. At least 255 of these vehicles were observed moving toward the central highlands of South Vietnam, and at least 281 moving toward the southern half of South Viet- nam. b. On 12 February an NVA logistic unit in southern Laos just west of the DMZ was observed preparing large vehicle convoys to move cargo to coastal central South Vietnam. c. On 17 February there were six vehicles towing 85-mm artillery pieces detected heading toward the southern half of South Vietnam from a major North Vietnamese logistic unit in the tri- border area.

Reliable evidence indicated that the North Vietnamese moved about 400 tanks through southern Laos and north- eastern Cambodia from 27 January to the end of February. The tanks were all clearly to be assigned to Communist units in southern South Vietnam or Cam- bodia. e. During the period 25 February - 25X1 1 March, over 5,160 NVA cargo trucks active between logistic entities in the southern Laotian Panhandle. Of this total, at least 330 were specifically headed toward South Vietnam, most toward the southern half of the country. f. Between 25 February and 1 March, over 60 cargo trucks were noted on the feeder routes from Laos into northern South Vietnam. A 50-truck convoy was also traveling on Route 922 into South Vietnam on 26 February. g. A large number of vehicles (exact number unknown, but less than 50) were detected returning from northeast- ern Cambodia to the tri--border area of Laos to participate in logistic activity there. It can be stated categorically that all activity in this area is directed toward the central highlands of South Vietnam. about 1,100 trucks were moving through the Ban Karai Pass from North Vietnam into southern Laos between 1 and 23 February. It is known that the cargo on these trucks included more than 2,000 tons of food and over 1,000 tons of ordnance. h. i. On 3 February, a 70-truck convoy was detected transporting ammunition in the area of eastern Laos between the DMZ and the A Shau Valley. In the same area, 194 NVA cargo vehicles were active on 3 February and 233 active on 5 February.

Between 13 and 16 February, there were 66 North Vietnamese vehicles observed moving ordnance to a storage area near Tchepone in southern Laos. C. NVA Logistic Movements Within North Vietnam, 27 January-28 February a. On 8 February, two rail cars of military goods were unloaded in the central Panhandle of North Vietnam. In- cluded in the manifest were 26 tons of munitions specifically earmarked for South Vietnam. b. On 14 February, eight tons of grenades were moving from the central Panhandle of North Vietnam to South Vietnam. c. An NVA logistic unit operating on the Song Ca River south of Vinh was shipping over 100 tons of supplies daily through its area during the period immediately preceding 23 February. This entity serves as a major transshipment point for supplies moving from Vinh southward toward southern Laos and South Vietnam. d. On 27 February, 65 cargo trucks were revealed on Route 137 north of the Ban Karai Pass. The direction of the trucks could not be determined. during the last three days of February there were about 2,500 tons of supplies moving between logistic units in the southern North Vietnam Panhandle. The types and specific destination of the cargoes were not obtained. 17. From 1 March through 31 March, traffic moving over the passes from North Vietnam into southern Laos continued to be heavy, and in Approved For Release 2006/03/06 : CIA-RDP78T02095R000700080091-8 Approved For Release 2006/03/06 : CIA-RDP78T02095R000700080091-8 the Laotian Panhandle, large numbers of vehicles were observed each day on the north- south routes of the central corridor and also along the feeder routes into South Vietnam. Communist road construction was also revealed at a number of points within South Vietnam. A. NVA Logistic Movements Within South Vietnam, l-31' March a. On Route 9 in Quang Tri Province: 1. There were 36 cargo trucks detected between Khe Sanh and the Laos border on 6 March. Direction of movement could not be determined. 2. Evidence of 6 March indicated that the North Vietnamese were up- grading a second runway at the Khe Sanh airfield. b. During early March, the Com- munists were observed constructing a road from the Route 165/966 intersection in southern Laos into Quang Tin and Quang Ngai Provinces of South Vietnam. The road was not close to any of the three "legal" border entry points which the Communists had requested as of that time. C.

Communist Violations 1. The GVN Joint General Staff (JGS) states that there was on 27 January 1973 a total of 31,810 RVNAF personnel held as POWs by the Communists. Of these the JGS states that 1,069 were captured in Laos and 531 in Cambodia. 2. As of 28 March, 5,018 of these prisoners of war had been released. Also, since the cease-fire, approximately 1,200 RVNAF personnel have been reported missing. This would bring the total RVNAF personnel possibly still held as POWs by the Communists to approximately 28,000. 3. The above GVN figures of POWs held by the Communists include missing RVNAF personnel as well as captured. The GVN has no way of telling how many of these men were captured and how many may have deserted, died, been induced to go over to the Communist side, or impressed into the Communist forces. 4. In the absence of firm data, it is impossible to give a true figure of the number of RVNAF personnel now held as prisoners by the Communists. The number is less than 28,000, but how much less it is impossible to say. 5. The GVN has compiled a list of actual names of 67,501 of its civilians detained by the other side since 1954. Of these, 16,754 were GVN local officials and government cadre. The Communists, however, initially claimed to hold only 140. They later raised this number to 428, and finally, on 20 April, agreed to release 637.

ARTICLE 15 This article states that the reunification of Vietnam must be accomplished through peaceful means and that, pending reunification, North and South Vietnam shall respect the DMZ. Communist Violations 1. North Vietnam has, since the cease-fire, moved sizable numbers of troops back and forth across the DMZ, and has (as stated earlier) moved thousands of tons of military supplies across the DMZ into South Vietnam. 2. North Vietnam has virtually annexed sizable areas of Quang Tri Province below the DMZ. It has not even engaged in the pretext. of a "PRG" administration in that part of Quang Tri Province under its control, but openly ad- ministers it directly through ministries and agencies of North Vietnam. In other words, for North Vietnam, the DMZ does not exist. Indeed, if challenged on this point, Hanoi's negotiators will probably cite the text of Article 15's subsection (a) as ample justification. This article is not pertinent to current Com- munist violations. (The article concerns the Four- Party Joint Military Commission, which has already been dissolved.)

The negative attitude of the Communist side has prevented the TPJMC from functioning as it was intended to function. The "PRG's" Chief Delegate (Tran Van Tra, an NVA General and alternate member of the Party Central Committee) has absented him- self from TPJMC meetings since 30 March. The "PRG" has not responded to the GVN offer to extend the FPJMC "privileges and im- munities" to the TPJMC. The "PRG" has failed to deploy personnel to points of entry designated under Article 7. The "PRG" has refused to discuss GVN pro- posals for prompt agreement on organization and deployment (based on ICCS deployments). The "PRG" delegation has not seriously re- sponded to GVN proposals to freeze major combat units and to begin delineation of zones of control. The "PRG" delegates have refused to discuss GVN-proposed procedures for establishing cease-fires in areas under Communist attack (e.g., Tonle Cham and Hong Ngu). (For one thing, the "PRG" insists on lower level contacts between opposing commanders. The GVN quite correctly suspects that this is more aimed at subversion. than at peace- keeping and insists that only those ARVN commanders who control all of the forces in an area [e.g., including artillery] should deal with the other side.)

Both this article and the Protocol to the Agree- ment on the ICCS state that the two South Viet- namese parties shall facilitate the operation of the ICCS teams and give them full cooperation, assistance, and protection. Communist Violations 1. The Communists have seriously hindered the operation of the ICCS and have frequently endangered the lives of the Commission's dele- gates. These forces have on a number of occa- sions fired on clearly marked ICCS helicopters and on 7 April shot down an ICCS helicopter in Quang Tri Province killing all nine pas- sengers aboard. The other side's explanation that this helicopter was off course ignores the fact that ICCS helicopters are not to be fired on under any circumstance -- neither, for that matter, are any other aircraft operating legitimately in GVN airspace and not engaged in acts of force. 2. The Communists have seriously threatened the safety of ICCS personnel by conducting numerous artillery and rocket attacks upon Tri Ton and Hong Ngu district towns where Com- mission members have been stationed. 3. The unwillingness of the Communist side to ensure the safety of ICCS inspections or travel in areas under their control has seriously impaired ICCS operations. This article is not pertinent to Communist violations.

Communist Violations 1. North Vietnam still maintains military forces in Laos and Cambodia, and shows no intention of removing them. 2. North Vietnamese Forces in Laos. Table 4 shows our current estimate o A forces in Laos. 3. The 38,000 NVA combat troops in Laos are organized into two infantry divisions and 13 regiments, as well as a number of inde- pendent battalions. The 47,000 administrative forces are principally engaged in operating and maintaining the Ho Chi Trail system in southern Laos. 4. From late 1972 until February 1973 the North Vietnamese steadily augmented their combat forces in Laos, both by deploying units from North Vietnam and creating units from personnel already in Laos. During the same period, the North Vietnamese also began an extensive reorganization of their rear services apparatus in southern Laos which involved the transformation of binh trams, which had per- formed a variety of functions, into regiments, each of which is engaged in one specific task, such as engineering or transportation. It is apparent, however, that the reorganization is not yet complete and that evidence of further changes probably will be forthcoming in the near future. 5. In addition to their own forces, the North Vietnamese continue to maintain an ex- tensive advisory presence in both northern and southern Laos. Although the number of Approved For Release 2006/03/06 : CIA-RDP78TO2095R000700080091-8 Approved For Release 2006/03/06 : CIA-RDP78T02095R000700080091-8 Order of Battle of North Vietnamese Military Forces in Laos 1 May 1973 Total Northern Laos Southern Laos Total 85,000 22,000 63,000 Regular combat forces 38,000 16,000 22,000 Administrative services 47,000 6,000 41,000 North Vietnamese advisers to Pathet Lao (PL) and neutralist forces is unknown, there is little doubt that there are advisers at all major command levels. Moreover, in order to instruct the PL, NVA troops occasionally have been attached to PL units on a temporary basis. Over the years, the NVA advisory effort has proven extremely valuable -- if not essential -- to the PL, both in terms of planning overall strategy and conducting daily tactical operations. 6. North Vietnamese Forces in Cambodia. Table 5 shows our current estimate of NVA and VC forces in Cambodia. Order of Battle of VC/NVA Military Forces in Cambodia 1 May 1973 Total 33,400 NVA 25,400 VC 8,000 Regular combat forces 5,000 NVA 3,500 VC 1,500 Administrative services 28,400 NVA 21,900 VC 6,500 Approved For Release 2006/03/06 : CIA-RDP78T02095R000700080091-8 Approved For Release 2006/03/06 : CIA-RDP78TO2095R000700080091-8 7. The 5,000 VC/NVA combat troops in Cambodia are organized into five regiments and several independent battalions. Almost all of the 28,400 administrative services troops and about 20% of the combat troops are located in the eastern part of the country. The disproportionately large administrative structure has a dual role, supporting both VC/NVA forces in South Vietnam's MRs 3 and 4 and VC/NVA and Khmer units in Cambodia. 8. In addition to providing support for VC and Khmer Communist (KC) units in Cambodia, the North Vietnamese have furnished an unknown but significant number of advisers to the KC military and political apparatus. The North Vietnamese commitment of combat troops?has de- clined markedly since the withdrawal of major units prior to the offensive in South Vietnam in 1972, and the KC have become increasingly autonomous in conducting combat activity. Nonetheless, the North Vietnamese continue to provide a significant level of logistical and some fire support in addition to their rela- tively small manpower commitment. The North Vietnamese also, of course, have an influential and possibly decisive voice in determining what military policies the Khmer Communists shall pursue.
