80k well equipped Chinese soldiers attacked 10k Indian soldiers in 1962 war. Regarding 1962,the IAF was not used in the Sino-Indian conflict where many military historians and retired officers claim that it could have altered the final outcome to a great extent. Indian government relied on inputs from the Intelligence Bureau (IB). The IB cautioned the government that the use of offensive air power could result in the PLAAF attacking Indian cities like Calcutta and also deny India the ‘moral high ground’ in case of a protracted conflict. No cognisance was taken of the fact that PLAAF aircraft could reach targets in India only if they operated from airfields in Tibet with the high altitudes imposing severe restrictions on their weapon-carrying capacity. On the other hand, IAF fighters would have had the advantage of operating with full weapon loads from airfields in the plains of Assam and Punjab.With over 22 combat squadrons and over 500 aircraft, the IAF’s mainstays in mid-1962 comprised the Hunter Mk-56 fighter-bomber aircraft, Gnat interceptor aircraft, French-built ground-attack aircraft such as Mystere and Toofani, Canberra bomber-reconnaissance jets, and the Vampire ground-attack jet. The PLA Air Force (PLAAF) was equipped with the MiG-15, MiG-17, MiG-19 and medium-range IL-28 bombers.
Remember the bloody nose Chinese have received during the 1967 Sino-India conflict. After 5 years of this conflict, Sikkim was merged with India
