Horth Vietnam's ability to maintain an effect!re military force, to famish coo tinned logistic support to Coos unlet forces in South Vietnam, and to withstand the effects of the allied boob-ing is largely da pendent on the continued receipt of naterial aid from other OoDCunlst countries. The USSR and Ccccanist China, which have beea tha principal suppliers of ailitary and eeononictance to Hanoi, considerably increased their aaaiatanee in response to the allied air offensive against Horth Vletaaau In general, both suppliers hare fornlshed that type of aaaiatanee Boat eoapatlble vith their available resources.

1. Holo of Military Aid ln the War Effort

The military sealstanco provided by the USSR and Corn unlet China hasey element in Horth Vietnam's military capability and in its attitude toward continuing the war. The Importance of this assistance has been frequently attested to in Vietnamese public statements- In Hanoi's view, Ccmaanlst military support provides atemblance of protection which inhibits farther allied cilitcry pressure on Horth Vietnam and helps to negate the effects cf tbo bashing. The Borth Vietnamese also regard thlo aid aa ox crenely valuable in eodtaining the military pressure that can be brought to bear In Sooth Vlotoam. Finally, Hanoi hopes that Joviet and Chinese aid serves to warn the US that Horth Vietnam can count on support frca the Communist camp despite the Sino-Soviet

5- Military Technical Assistance

a In addition to providing military equipment, bothnd Communist China have provided military advisers and The Chinese contribt/tior: in this area has been far greater than that of the USSR. It is estimated thai0 Chinese support troops are in Worth Vietnam working on the construction, repair, and -defense, of transportation facilities. An unknown number of Chinese military personnel also are employed In the training of North Vietnamese troops.

In contrast, the number or Soviet military technicians probably did notn the peak yearhen the USSR exercised operational control of the SAT system- Since then, vhe role of Soviet technicians has beer, essentially one of advising

rather than ooo of operational control. It la currently estimated that the number of Soviet military technicians in Borth Viotnaa ranges. In addition to those asaociatod with the RAM system, other Soviet technicians are engaged in flight training, aircraft minterjaaoe, and logiatio support activities. AHorth Korean contingent of aboutlight personnel Is also providing training for the Borth Wetnaneoe air force.

Although tho possibility thatSoviet militarymay have been delivered by cea coanot be ruled out, we are confident that no major weapons system could tvive gouc into North Vietnam by oca without detection by US intelligence. He therefore estimate that the major itcam of military hardware for Horthhave been delivered by means of the Chinese rail system. Sea transport has been osed largely for coronercial goods, including those in the defense-supportrucks andequipment. The USSR also has delivered by sea soaeelicopterswhichual civil and military use and some opare parts for transport aircraft- The public debate between thc USSR and Communist China concerning tho transit of Soviet military goods, as wall as other information, reinforces our judgment that military goods have moved by rail rather than by sea.
