In April 1971, Sqn Ldr Charanjit Singh was awarded the Vishisht Seva medal for professional competence and dedicated service.
During the Indo-Pak war in December 1971, he undertook a large number of missions over enemy territory and brought back very valuable information on enemy targets and dispositions. This greatly helped in planning and execution of operations. With full knowledge of the dangers involved, he volunteered and undertook these missions cheerfully. In these missions he penetrated deep into enemy territory fearlessly during daytime.
Throughout the operations, he displayed gallantry, determination and devotion to duty of a high order.
