The Prospects of War in South Asia

During the Next 90 Days

 

Purpose

To assess the likelihood of the outbreak of hostilities in South Asia over the next 90 days, the possible courses of action by India and Pakistan, and probable Soviet and Chinese Communist military re­actions to the range of possibilities.

 

Summary and Conclusions

The probability of war between India and Pakistan will remain high for the next 90 days. Both sides have made extensive military de­ployments and are prepared to react to an attack on their territory. A sharp increase in fighting in East Pakistan is expected over this pe­riod which will further raise emotions on both sides, escalating the possibility of war. Unless there is a political breakthrough, the ques­tion is not whether there will be a war, but rather when it will occur.

 

Neither India nor Pakistan desire war, and neither is economically able to engage in a prolonged contest. However open hostilities could result from an escalation of border clashes, a Pakistani attack on guerrilla camps in India, a killing rampage in East Pakistan, mis­calculation of the other side's intentions, or a high flow of refugees. The more likely causes would be escalation of the border clashes or miscalculation.

 

Internal politics in East and West Pakistan are pushing Pakistan to­ward economic disaster and a military debacle. Pakistan in response to Indian provocation may attack India and seek an early interna­tional solution if it sees no other way to retain East Pakistan. In such case, Pakistan would attempt to bargain with any territory it seized in the West against the loss of East Pakistan. India would probably at­tack in the East if the Mukti Bahini encountered serious reverses. The actual timing of an outbreak of hostilities is difficult to deter­mine. Certainly, Pakistan would move only in desperation.

 

International pressures on both sides and on-going diplomatic actions have been increasing in an effort to prevent an all-ouwar. They have not been successful, however, in persuading Pakistan to adopt a po­litical solution which would induce the more than nine million refu­gees to return to East Pakistan.

 

The situation in the East could be resolved by Pakistan if India could be constrained from direct intervention, but a political settlement there, acceptable to both India and Pakistan, will be required to re­duce tensions between them significantly.

 

During the next 90 days some important concessions on the part of either side such as Pakistani negotiations with representatives of Mujibur Rahman or Bangla Desh, a mutual withdrawal of some ma­jor forces from the borders, or a measurable decrease in Indian sup­port of rebel activities could improve the situation. The danger of war, however, will persist until an acceptable political solution is found and the refugees return to East Pakistan.

 

Open conflict between India and Pakistan is likely to begin in East Pakistan and could well be initiated by India. The balance of forces favors India in this area, but the war would quickly spread to the West as Pakistan would seek territorial gains to offset its losses in the East. An initial Pakistani attack in the West would probably oc­cur in Kashmir and be followed by an Indian attack in the Punjab toward Lahore.

 

War would be fought primarily by ground forces. Air actions would be more intense in the West than in the East but after three or four weeks would be constrained by shortages of munitions, spare parts, maintenance of aircraft and POL. A major naval engagement would be unlikely although some individual ship actions could occur. India may establish a blockade.

 

India is capable of launching a two-front war and should prevail over Pakistan because of its greater manpower and logistics strength. It is doubtful that Pakistan could sustain large-scale military action for much more than a month; thereafter the intensity of its effort would be reduced to guerilla-type activities. The actual duration of the war would more likely be determined by international political-economic pressures and the willingness of both parties to accept a negotiated settlement.

 

It is not believed that either the Soviets or Chinese Communists would commit their own forces in a military reaction to a conflict in South Asia. Both, however, would probably continue to provide military supplies and assistance. If China wished to cause serious concern in India, it could take limited border actions but would probably not use major forces or seize Indian territory to avoid a possible Soviet reaction or direct Chinese involvement in the con­flict.

 

Discussion

The probability of war between India and Pakistan remains high for the next 90 days. Open hostilities could result from: 1) An escalation of the present border clashes: 2) Pakistani raids on guerrilla training camps in India: 3) a continued high refugee flow with a cumulative total of over 9.500.000: 4) a Pakistan Army killing rampage in East Pakistan: or ii a miscalculation of the other side's intentions. Both sides have made extensive military deployments and are prepared to react to an attack of their territory.

 

A sharp increase in fighting in East Pakistan is expected over this pe­riod as the Pakistan Army seeks to defeat the Mukti Bahini rebels and put an end to their military operations. This situation will further raise emotions on both sides thus increasing the chances of war. Un­less there is a political breakthrough, the question is not whether there will be a war, but rather when it will occur.

 

There are, however, a number of factors which mitigate against the outbreak of open hostilities. Neither India nor Pakistan desires con­flict, and neither is economically able to engage in a prolonged war without outside support. The prospects for substantial outside assis­tance in the event of war appear less than encouraging for either party.

 

International pressures on both sides and on-going diplomatic actions have been increasing in an effort to prevent an all-out war, but none has yet been successful in persuading Pakistan to adopt a political solution which would induce the refugees to return to East Pakistan.

 

The Situation in India

Although India's primary stated interest has been the settlement of the refugee problem, New Delhi's support of the liberation move­ment in East Pakistan continues to increase the chances of conflict with Pakistan. India has been providing training and support for the East Pakistani guerrillas and soliciting world-wide support for aid and for the return of the refugees. Nevertheless, New Delhi has shown restraint in taking initiatives which might provoke open hos­tilities. It would be to India's advantage to see that these matters are settled peacefully, if possible. Further, a quick settlement would pre­clude the radicalization of the masses in East Pakistan and the possi­bility of a takeover by a leftist-oriented regime in the Bangla Desh organization, which could be costly to the Indians in the longer term.

 

Although India has received support from Moscow, Soviet officials have advised the Indians to exercise restraint. The Indian-Soviet Treaty of Peace, Friendship and Cooperation (of August 1971) pro­vides for mutual consultations in case of attack or threat of attack against either signatory. This treaty has quieted, at least temporarily, the New Delhi hawks. The treaty provides for Soviet political and military material support in the event India is attacked. It is less defi­nite on Soviet assistance if India should attack Pakistan. Prime Min­ister Gandhi appeared disappointed during her 27-29 September trip to Moscow when the Soviets refused to condemn Pakistan for total responsibility in the Bangla Desh situation and, cautioned India against over-involvement in support of the rebels. However, Moscow did express confidence that it could influence Islamabad to accept a political settlement which would permit the return of the refugees. We doubt, however, that Moscow will be able to influence Pakistan to this extent.

 

The recent disclosure of India's strategy against Pakistan helps clar­ify its moves. India believes that war is not inevitable but that the threat of war is necessary to force Pakistan into an acceptable solu­tion. New Delhi is convinced that if its pressure in the West prevents Islamabad from reinforcing its military efforts in East Pakistan, the province would be lost to the rebels. The Indians believe that this, coupled with Islamabad's awareness of the dangers of open conflict, should force Pakistan to negotiate.

 

Several Indian actions become clearer in the context of this strategy. The recent northward movement of sizable forces toward West Paki­stan was presumably calculated to peak the pressure. In addition, New Delhi has refused President Yahya Khan's proposal for a mu­tual troop withdrawal from the border areas. The dramatic increase in propaganda, particularly in regard to border crossings and clashes, has also increased the pressure on Pakistan and focused world atten­tion on the crisis.

 

Despite official statements to the contrary, India's reserve call-up in October also increased the pressures and the chances of war. The ac­tivation of army reserves and selected naval and air force personnel has been confirmed by New Delhi. The contribution that these forces -- 44,000 effectives out of a total of about 700,000 available -- could make, however, is slight. The vast majority of the reserves, such as students, would require too much training to make them of immedi­ate consequence. Nevertheless, Islamabad undoubtedly concludes that the call-up increases the threat.

 

Prime Minister Gandhi has emphasized that the mobilization was precautionary. Her brief speech to the nation on the eve of her de­parture for Europe and the US failed to mention the matter of re­serves, and its mild tone may have eased Pakistani fears. Moreover, in an address to the Defense College shortly after she left, Defense Minister Ram asserted that India would not take any step that could be regarded as aggression against Pakistan.

 

India will continue to keep pressure on Pakistan by assistance to the guerrillas and appeals to the world for aid to the refugees. However, should large-scale communal strife develop in the refugee areas, Pakistan attack guerrilla bases in India, or widespread killing occur in East Pakistan, New Delhi would probably seek a military solution to the problem and attack Pakistan within the next 90 days.

 

The Situation in Pakistan

Islamabad's suppression of East Pakistan's independence efforts on 25 March 1971 gave rise to serious internal military and economic problems. The arrest of Sheikh Mujibur Rahman, the outlawing of the Awami League, the military suppression of East Pakistan and the proclamation of the Independent Republic of Bangla Desh by guer­rilla leaders in India have added to those problems and caused a heavy flow of refugees to India. However, some remedial actions taken by the government such as the amnesty proclaimed in early September, the appointment of a civilian governor in East Pakistan, and the announcement of by-elections in East Pakistan in December may reduce tensions in the longer term. While these remedial actions have been somewhat encouraging, they have yet to attract any sig­nificant popular support toward a settlement of the situation. Further genuine moves on the part of West Pakistan will be required before prospects for a settlement can be seen.

 

Although the deterioration of the economy has been discouraging, the threat of famine is subsiding in East Pakistan now that the critical inter-harvest period is drawing to a close and programs to distribute imported food grains are progressing. Economic support from China and the Muslim states as well as assistance from the US and other Western countries have tended to relieve the pressing economic situation, but the country's foreign exchange position has substan­tially declined in the past year. Moreover, the loss of production and exports in East Pakistan is affecting even West Pakistan business­men.

The West Pakistan military forces retain de facto control in East Pakistan, although the government there has been officially returned to civilian hands. The administration is almost paralyzed by the military situation and social turmoil. Security deteriorated further during the rainy season. Government forces have been unable to pre­vent harassment, terrorism or sabotage throughout the countryside, or even in major urban areas, by Mukti Bahini rebels.

 

As the monsoons come to an end, a sharp increase in military actions in East Pakistan is expected over the next two months. Government military leaders will be able to launch major actions to suppress the guerrillas and should be able to contain them if the Indians do not intervene and if they do not permit excesses by government troops against the population. Continued Pakistani attacks in the border ar­eas or an attack against rebel training areas in India, however, would likely precipitate an Indian retaliation that could result in full-scale war.

 

On balance, internal politics in East and West Pakistan are pushing Pakistan toward economic disaster and a military debacle. The situation in the East probably can be resolved if India can be constrained from direct intervention, but a political settlement in East Pakistan, acceptable to both India and Pakistan, will probably be required to reduce tensions between them sufficiently to preclude a war.

 

During the next 90 days some important concessions on the part of either side such as Pakistani negotiations with representatives of Mujibur Rahman or the Bangla Desh, a mutual withdrawal of some major forces from the borders, or a measurable decrease in Indian support of rebel activities could improve the situation. The danger of war, however, will persist until an acceptable political solution is found and the refugees return to East Pakistan.

 

Scenarios Which Might Escalate to War

The key issues which could spark a full-scale war include 1) seizure of East Pakistan territory by India; 2) Pakistani raids on guerrilla training camps in India; and 3) a continued refugee flow which could force New Delhi to take military action because of social and eco­nomic problems. Other events which could escalate into open war­fare, although less likely, involve 1) Indian recognition of Bangla Desh guerrillas, 2) a Pakistan Army killing rampage in East Pakistan, 3) Islamabad's decision on the ultimate fate of Sheikh Mujibur Rah­man; and 4) famine in East Pakistan or communal unrest in the refu­gee areas of India.

 

Mrs. Gandhi's return to New Delhi on Saturday and the reconvening of the Indian Parliament on Monday, November 15, will cause pres­sures to mount rapidly for a decision on India's future actions. In making a decision, Mrs. Gandhi will be influenced strongly by her assessment of her western visit and advice from certain trusted advi­sors, particularly General Manekshaw, the Indian Army Chief of Staff.

There are at least four options available to India: 1) continue the pre­sent policy of pressuring Pakistan into a political settlement; 2) rec­ognize Bangla Desh hoping to provoke a Pakistani attack; 3) provoke Pakistan through greatly increased Indian-supported Mukti Bahini operations; or 4) launch an Indian attack. It is believed Mrs. Gandhi favors the first option, but her advisors and internal pressures could move her toward one of the others. If she is convinced that all hope for negotiation has passed, she may feel justified in a decision for

military action. If so, we believe she would decide that the best op­tion would be to increase Indian-supported Mukti Bahini operations to pressure Pakistan into a military reaction. Either side could be ir­rational.

 

If open conflict should break out it may be difficult to determine which nation initiated the attack. It is likely hostilities would result from an escalation of the present border clashes in East Pakistan, or by miscalculation. It is less likely to result from air or naval inci­dents.

 

There have been border clashes between Pakistan Army units and Bengali guerrillas in which, Pakistan army units have also engaged Indian Border Security Force and regular army units in small arms, mortar and artillery exchanges. Although occurring frequently, the clashes have been brief and have involved only small units (squads, platoons or companies). Should these actions involve larger forces such as brigades or even a Division, they might well escalate into open hostilities. There have been reports that the guerrillas are infil­trating larger numbers of personnel into East Pakistan. Such action is likely to precipitate larger-scale actions by the West Pakistan forces and could lead to brigade or Division actions.

 

A miscalculation of the other side's intentions could occur if either maneuvered present forces in a feint or took such other military ac­tion as might be interpreted as preparations for an attack. Addition­ally, should the Pakistan Army go on a killing rampage in East Paki­stan to counter guerrilla actions, it could arouse Indian sympathies to the extent New Delhi might feel compelled to intervene. A miscal­culation of the other side's intentions is considered a likely way in which the current situation could evolve into a full-scale war.

 

Possible Courses of Action

 

East Pakistan

Open conflict between India and Pakistan is likely to begin in the East Pakistan and could well be initiated by India. India could com­mit the Infantry and 9th Mountain Divisions and the 50th Parachute Brigade from the Calcutta area without seriously jeopardizing its de­fense of the West Bengal state border. The 3rd Independent Light Armored Brigade, with 135 PT-76 light amphibious tanks could spearhead brigade of the 20th and 23d Mountain Divisions in an at­tack from the north, while the 57th Mountain Division and elements of the 8th Mountain Division could attack from the East. Regular In­dian Army forces immediately available are some 92,500 combat personnel and approximately 200 tanks supported by an additional 23,000 Mukti Bahini guerrillas. Additional troops could be quickly brought to the area if not needed in the West or if a Chinese attack failed to materialize. (See Map I for opposing forces).

 

To avoid overcommitting Indian forces in East Pakistan, the Indians could elect to attack initially from the Calcutta area and from the north. This would permit them to draw Islamabad's forces into a holding action prior to an attack from the East. The Indians' princi­pal problem would be to avoid becoming tied down in a prolonged engagement. At the same time, however, these forces would be ex­pected to seize maximum territory for bargaining purposes. Pakistani forces in the East number approximately 60,000 regular combat personnel and 12,000 paramilitary and police. But, while the strength of the opposing forces favors the Indians, the terrain in the south would be likely to channelize their efforts and assist the Paki­stanis in the defense of the area. Indian transportation and logistics problems could also slow the advance significantly. On the other hand, the Pakistani forces are widely dispersed and require time to organize an effective defense. An additional factor would be their lengthy and vulnerable supply line from West Pakistan.

 

India should be able to defeat the Pakistan forces in East Pakistan within four to six weeks.

 

West Pakistan

Should hostilities break out in East Pakistan, Islamabad would be likely to initiate an attack in the West, most likely in the Kashmir area. The Pakistani objective would be territorial gain in this dis­puted area for use as a bargaining point in the event India takes East Pakistan.

 

Initial Pakistani attacks across the cease-fire line would probably be conducted by the 12th and 23d Infantry Divisions in company with the 8th and 15th. The 12th Division would most likely thrust into Kashmir from the northwest, fully aware that the 25th Indian Divi­sion would move to counter. They also would know that the 19th In-

than Division to the north would send elements to reinforce the 25th. The 23d Pakistan Division would move against the 26th Indian Divi­sion. (See Map 2 for dispositions of forces).

 

Pakistani 8th and 15th Divisions would most likely direct their ef­forts towards the Banihal Road in an effort to sever this only Indian major land LOC in Kashmir. Logistics support is furnished to four Indian Divisions (one of which is along the India-China border) and the XV Corps Headquarters over this road.

 

Backing up this Pakistani force would be the 17th Infantry Division as well as the 6th Armored Division. The latter would be of little use within Kashmir because of the rugged mountainous terrain. It could, however, be effectively employed should the 26th Indian Division attempt to cross the cease-fire line.

 

The five-Division Pakistani infantry force is composed of approxi­mately 75,000 personnel. The 6th Armored Division has 237 tanks plus some 13,000 personnel. The three-Division (excluding the China-border unit) Indian force in Kashmir consists of about 60,000 troops.

 

India, on the other hand, would likely attack Pakistan in the Punjab in response to offensive operations by Islamabad. Two Divisions - the 7th and possibly the 15" - and an independent armored brigade would initially attack along an Amritsar-Lahore axis to outflank de­fending Pakistan forces, with Lahore as their objective. Forces at­tacking toward Lahore would be confronted with concrete-banked ir­rigation canals which cannot be crossed by tanks without bridging equipment.

 

The movement of the Indian 1 st Armored Division, the 36th and 54th Infantry Divisions, and the 2nd Independent Armored Brigade north from base areas in central India has significantly increased In­dia's options in the area. At a recent Indian Army Commanders con­ference, the Indian Army Chief of Staff, General Manekshaw, stated that the primary Indian targets would be Lahore, Sialkot and other Pakistani border towns. Should Pakistani resistance prove stubborn, a supporting Indian attack would be launched in Kashmir. Two Paki­stani infantry Divisions, the lOth and l lth, defend at the canals. Be­hind them, the 6th Armored and two infantry Divisions could serve as reserve and defend Islamabad against a possible Indian break­through. The 7th Infantry Division at Peshawar could also be used. (See Map 3 for opposing forces).

 

Pakistan would probably not choose to attack across the Indo­Pakistani border in the Lahore area of Punjab, in part because of the strength of Indian forces in the area and its logistical problems, espe­cially ammunition shortages. The 10th and Ilth Divisions, head­quartered at Lahore, can be expected to maintain a defensive posture around the city and to defend the approaches to Islamabad.

 

The initial Indian attack force would be composed of approximately 41,000 troops and 150 tanks. Reinforcements in the area would in­crease the force to at least 100,000 troops. Pakistani troops defending Lahore number 30,000 men. The defenders could be reinforced by about 50,000 troops.

 

Naval Actions

A major naval engagement is unlikely. Individual ship actions could occur and would probably include encounters by ships on patrol, submarine attacks on targets of opportunity, and isolated shore bom­bardment missions. (See maps 4 & 5 for disposition of the naval forces).

 

Due to the numerical superiority of the Indian fleet, ships would be available to protect major Indian ports and shipping. In addition, na­val units could be used off South India and in the Arabian Sea for shipborne air surveillance since shore-based early warning radar in this area is lacking. Sufficient ships are based in Vishakhaputnam to blockade East Pakistan. A less likely possibility would be an attempt to blockade Karachi with Indian OSA class boats and submarines operating out of West coast ports. A blockade, however, could put India into a confrontation with third countries and might not be con­sidered worth the risk of an incident.

 

The Indian aircraft carrier VIKRANT, with its limited propulsion ca­pabilities, is not presently capable of launching aircraft except in an emergency and would probably be positioned in southern India at Cochin or Madras to avoid any possible loss.

Pakistani naval activity would probably be confined to the area south of Karachi, and then only in small or single unit forays or patrols.

 

DAPHNE-class submarines could attack patrolling Indian ships, but would probably not venture far from Karachi. In the East, Pakistan has only four motor gunboats located in East Pakistan to counter In­dia's Eastern Fleet. They would probably not engage Indian ships.

 

Air Actions

Air activity, both strategic and tactical, would be more intense in the West than in the East. Both air forces would probably be used ini­tially to strike airfields to establish air superiority and subsequently provide support to ground forces. Strikes against major population centers could be expected during the early stages of the conflict for their psychological value.

 

The air war would probably be constrained after a few weeks by shortages of munitions, spare parts, POL, and maintenance problems. The logistics situation would definitely favor India, while individual pilot capabilities would probably favor Pakistan, although their pilots would be outnumbered.

 

Indian air supremacy in the East should be quickly achieved. If India launched a preemptive airstrike in the West, it should gain air supe­riority within two weeks. However, a Pakistani preemptive air strike would degrade the Indian air capability in western India. If neither side elected to initiate hostilities with a preemptive air strike, the air war would be prolonged. The Indian Air Force should eventually win, and the remnants of the Pakistan Air Force would be grounded by logistic/maintenance problems.

The Indian Air Force has four squadrons of Hunters in Eastern India in a fighter/bomber role, and three squadrons of MIG-21's and three squadrons of Gnats for air defense. After initial attacks on East Paki­stan these fighters would resume their defensive posture against a possible attack from China. The Pakistan Air Force has only 18 F-86 aircraft in the East and could offer only token resistance. (See map 6 for opposing Air Forces in the East).

 

In the West, India has five squadrons of SU-7s, two squadrons of Hunters, and one squadron of Mysteres immediately available in the fighter/bomber role. (See map 7 for Indian Air Force dispositions). A squadron of Canberra light bombers is also available as well as five squadrons of MIG-21s and four squadrons of Gnats deployed in an

air defense role. In reserve are two squadrons of Canberras, one squadron of SU-7s, a squadron of Mysteres and two squadrons of HF-24s.

 

In the West, Pakistan has five MIG-19/Mirage III-E, two Sabre M-6, four F-86s, one F-104, one B-57 squadron and one IL-28 squadron, the latter consisting of only four aircraft. (See map 8 for Pakistan Air Force dispositions). Aside from preemptive air strikes and bomber raids for psychological purposes, the Pakistan Air Force would be forced to fight primarily in an air defense role, although some initial support could be provided for the ground forces.

 

Probable Outcome

India is capable of launching a two-front war against Pakistan. As­suming no foreign military intervention, India should prevail over Pakistan in either a one or two-front war. But, since any major conflict between the t%\ o countries would be supply-limited, both parties would probably be willing to negotiate an early end to the conflict.

duration of the war is difficult to assess. From a milltary standpoint it is doubtful that Pakistan could sustain military ac­tion for much more than a month: thereafter the intensity of its effort would be reduced to guerrilla-type activities. India should be able to defeat the Pakistani forces in East Pakistan within four to six weeks. In the West, both sides would probably reach an initial standoff within two weeks, but in a prolonged conflict, India's greater strength and stronger logistic position should prevail. The actual du­ration of the war, however, would more likely be determined by in­ternational political and economic pressures and the willingness of both parties to accept a negotiated settlement. Neither side can afford a war of attrition.

 

Major limitations on India's offensive capability are: I) the shortage of spare parts for modern weapons systems, 2) an inadequate com­munications system, 3) a transportation system which is marginal in certain critical areas, and 4)a limited industrial base to support a major military effort. India is believed to have a 30-day supply of ammunition and other expendable items. The military POL reserve is estimated at 30-45 days. India can probably double the output of its war-production facilities and this, together with foreign assistance, should sustain Indian forces for two or three months.

 

The ability of the Pakistan Army to logistically support either offen­sive or defensive operations is limited. The logistics system has been taxed severely by the necessity to supply the effort in the East. The wide variety of equipment further aggravates the repair and supply problem. In West Pakistan, we can expect the army to be a formida­ble force for about 30 days. Beyond this, restrictions on imports and dwindling supplies would probably stop offensive action. In East Pakistan, immediately available supplies are believed to be small and re-supply extremely difficult.

 

About 85 per cent of the Pakistani crude oil requirement is imported from Iran through Karachi. India could impose a blockade and Paki­stan would be restricted to its own meager resources. Pakistan has only an in-country production capability of about 10,000 barrels per day. Available jet fuels would support the air force in the West for approximately 35 days and in the East for about 25 days.

 

The Chinese Threat

Chinese ground combat forces immediately adjacent to the Sino­Indian border are roughly estimated at about 60,000 combat person­nel and about 10,000 support personnel. The major combat units in­clude three infantry Divisions, one independent infantry regiment and five border defense military internal security regiments. (See Map 9). Support units include one independent artillery regiment, one AAA regiment, two engineer regiments, two motor transport regiments and one signal regiment.

 

Although there are no tactical aircraft deployed near the Indian bor­der at this time, there are five airfields in southwest Sinkiang and Ti­bet which could accommodate tactical jet fighters. These could sup­port a ground effort against India to a range of about 300 nautical miles beyond the border. Two of the five bases are suitable for IL-28 operations. A"mix" of light bombers/fighters could be employed. A further 300 fighter aircraft could be employed from four bases in southwest China for operations against eastern India. Two other bases could support up to 150 IL-28s. China's TU-16/Badger medium jet bombers could strike any target in India from interior bases, but would probably be held in strategic reserve.

 

In an all-out effort, a maximum force of 150,000 ground combat per­sonnel supported by 300-350 tactical aircraft operating from airfields in Tibet and southwest Sinkiang could be logistically supported. Cur­rent ground force units can be reinforced by nine infantry Divisions within 30 days. Five Divisions could be drawn from the Chengtu area and four Divisions from the Hsining/Lanchou area.

 

To oppose these forces, India normally employs eight Divisions to protect the Sino-Indian border. East of Nepal, New Delhi maintains six Divisions, three in or near Sikkim and three in the North East Frontier Agency (NEFA). Two Divisions are located in Ladakh west of Nepal. In addition. the 3d Independent Light Armored Brigade, equipped with 135 PT--6 tank,, is located in the Siliguri Gap.

 

AIthough an Indian invasion force into East Pakistan would include some elements drawn from units currently in reserve against a Chi­nese invasion, to ensure adequate protection along the Sino-Indian border India would probably maintain six Divisions and elements of two other;.

 

Soviet and Chinese Communist Reactions

It is not believed that the USSR would commit its own personnel in an overt operational role in the subcontinent except in the unlikely event the Chinese joined Pakistan in an attack on India or other ma­jor powers became militarily involved against India. None of the potential conflict situations on the subcontinent would involve hos­tilities in direct proximity to Soviet borders or threaten the USSR.

 

The Soviet-Indian Treaty is probably judged by the Soviets as one means of deterring conflict in the area. It also provides a basis for continued Soviet interest in and military and economic assistance to India. Soviet support is predicated on India being the victim of ag­gression. Should hostilities occur, however, it may be impossible to establish the aggressor with both Islamabad and New Delhi claiming self-defense. The Soviet response in this situation would probably be based on other considerations, including an assessment of China's likely course of action.

 

From the beginning of the crisis, the Soviet Union has preached re­straint to both India and Pakistan. If a conflict should develop, India would probably not request Soviet forces to fight Pakistan in view of India's relative strength unless the Chinese intervened militarily. Pe­king is not expected to do so. On balance, a direct Soviet military re­action would be highly unlikely, although the Indians probably would receive military assistance.

 

Although the Chinese Communists would have the capability to at­tack India directly, due to their common border, they would not be likely to become involved beyond providing some supplies and as­sistance to Pakistan. Current Chinese efforts toward improving their world image, and gaining acceptability as a world power would be seriously jeopardized if they entered a conflict on the subcontinent. An Indo-Pakistani war would not threaten the Chinese directly, while the possibility of a confrontation with the Soviets would provide a strong deterrent to,Chinese military action.

 

If the Chinese wished, however, to cause serious concern in New Delhi and to make India reluctant to commit additional forces to the conflict with Pakistan, they could deploy additional units and aircraft to the Indian border area, carry out a show of force, or launch limited probes or harassing actions along the border. These border actions would not involve major forces or the seizure of Indian territory. They would be designed to avoid a possible Soviet reaction or direct Chinese involvement in the conflict.
