In April, the Soviet Union's political support for North Vietnam materialised with the delivery of MiG fighter planes and SAM-2 anti-aircraft missiles, along with large quantities of food and ammunition. In addition, Soviet pilots and other specialists were dispatched to North Vietnam to train North Vietnamese military personnel in the use of advanced military hardware. China, not to be outdone by its Soviet rival, increased the delivery of armaments to North Vietnam at rates which surpassed their commitments in 1964. China also offered logistical assistance to the North Vietnamese military by providing seven divisions of Chinese soldiers for road construction and other projects. The logistical support offered by China had a significant impact on the North Vietnamese military, as North Vietnam needed all its combat divisions to conduct operations, to aide the Pathet Lao in Laos and the VC in South Vietnam.
