As a Hunter pilot during the 1965 Indo-Pak war, Sqn Ldr Ajit Singh Lamba flew a total of 15 operational sorties, 11 in close support of the Army in the Kasur and Lahore Sectors. He showed great skill and determination in seeking out enemy targets and pressing home his attacks in spite of intense ground fire and the presence of enemy interceptor aircraft.
He successfully destroyed several enemy tanks and vehicles. His achievement in the destruction of enemy guns and armour near Harbanspura railway station was specially noteworthy because of the heavy defences surrounding these locations.
Throughout the operations, Sqn Ldr Lamba showed a marked keenness for action and was always an immediate and ready volunteer for any mission. His courage and devotion to duty inspired other pilots and were in the highest traditions of the Air Force.
