Second Lieutenant Ajit Singh was a company officer in a battalion of the Grenadiers. On 4 December 1971, a patrol led by a JCO came under heavy machine gun fire. Second Lieutenant Ajit Singh, who was about one kilometre away with his platoon, heard the firing and rushed to the spot and fighting courageously helped the patrol to move to a safe place. Again on 6 December, during the attack by his company on an enemy position, he moved to the flank taking one 3-inch mortar and a machine gun and kept on harassing the enemy by firing from different positions. His bold and aggressive action broke the enemy's resistance and assisted the company in capturing the objective.
On 14 December when out on a patrol, he infiltrated behind the enemy, forcing him to beat a retreat. When the patrol advanced further, it came under heavy mortar and machine gun fire from an enemy battalion. He, however, managed to extricate his patrol. At this time, his wn screen position was under heavy pressure of enemy attack. With utter disregard for his safety, he deployed the 3-inch mortar and machine gun and brought down effective fire on the enemy inflicting heavy casualties.
Throughout, Second Lieutenant Ajit Singh displayed gallantry, initiative and leadership of a high order.
