After the Sino-Indian War of 1962, the regiment, as with the rest of the armed forces, saw expansion on an unprecedented scale, with the 5th battalion raised in 1962, the 6th battalion raised in 1963 and the 7th battalion raised in 1964, followed by raising of the 8th battalion. A second parachute brigade, the 51st, was also raised to complement the 50th Brigade but was reverted to normal infantry role in 1976.
