Following high-level talks during the 2020 skirmishes with the PLA in eastern Ladakh, 16 Bihar monitored the Chinese forces in the Galwan Valley to ensure their disengagement. According to Indian sources, on 14 June, a group of PLA troops erected tents and an observation post on the LAC in contravention of an agreement made on 6 June and India's perception of the Line of Actual control. Babu led a delegation and made an attempt to communicate, which soon resulted in a fistfight with both sides sustaining injuries. Reinforcements were sent for, more melee continued resulting in more injuries on both sides. The Indian military said that in response, the soldiers of 16 Bihar 'reportedly' killed 40 to 45 soldiers of PLA in hand-to-hand combat and inflicted heavy casualties upon them. The PLA admitted the death of at least four of its soldiers.

Babu was promoted lieutenant-colonel on 10 December 2017. After serving as a divisional officer and Instructor Class "B" at the NDA, he was appointed a GSO I at the HQ of 35 Infantry Brigade. He received another posting to Jammu and Kashmir in 2019, and assumed command of 16 Bihar on 2 December 2019. He was promoted full colonel in February 2020. At the time of his death, he was expecting to be posted to Hyderabad.

In 2009, Babu married Santoshi. The couple had a daughter Abhigna (aged nine at her father's death) and a son Anirudh (aged four). His family resided in Delhi.

During his service, he was attached to the Rashtriya Rifles in Jammu and Kashmir, and also served with the UN peacekeeping force in the Democratic Republic of the Congo (DRC) during the ongoing Kivu conflict. Colleagues who served with him described him as "empathetic, yet bold." During a major joint operation conducted by DRC and South African forces against Nduma Defense of Congo (NDC) rebels, Babu and his unit were caught in cross-fire, yet his actions aided in preventing the rebels from inflicting casualties on the joint force. During his posting in the Congo, Babu was described as kind and generous towards local residents, assisting them with medical and other needs.
