Battle of Phillora on 11 September 1965 by sheer gallantry of legendary
Lieutenant Colonel Ardeshir B Tarapore. The regiment spearheaded the Indian advance into Pakistan and cleared the stronghold of Phillora after a gruelling close range tank battle against Patton tanks, in which 23 enemy tanks were destroyed.

Indo-Pakistani War of 1971 (
Battle of Basantar) The Poona Horse under the command of 47 Infantry Brigade was ordered to establish a bridgehead across the Basantar river in the
Shakargarh sector. The brigade's engineers were in the process of breaching the enemy minefields and create a safe lane that would allow the induction of the tanks. In view of the alarming activity of Pakistani artillery, the Poona Horse with its Centurion tanks decided to push through the minefield despite it being only partially cleared by that time. En route, while crossing the Basantar River, the tank troops came under fire from Pakistani tanks as well as recoil gun nests that were still holding out. They retaliated fiercely — destroying tanks, capturing gun nests and over-running enemy defences. 2nd Lieutenant
Arun Khetarpal, who was posthumously awarded the prestigious Param Vir Chakra, was responsible for the destruction of 7 Pakistani tanks. The following days saw Indian troops making massive gains and conducting successive military thrusts deep inside enemy territory, coming threateningly close to the Pakistan Army base at Sialkot. India's resounding victory in the Battle of Basantar resulted in the capture of a significant area ( including nearly 500 villages) under the control of Pakistan in Chhamb sector, apart from cutting off the line of retreat for Pakistani troops. ;Other operations / achievements - • The regiment had the honour to participate in the
