In late 1989, Singh was approved to be promoted to the rank of Colonel and cleared to command a battalion. In early 1990, the battalion embarked for Mumbai. Shortly thereafter, Singh was appointed Chief Instructor of the Commando School at Belgaum, where he had earlier served as an instructor. He was earmarked by the Colonel of the Regiment to take over command of 24 Rajput, but Singh was determined to get back to his old battalion (2 Rajput) or take over the battalion he served with in Sri Lanka (25 Rajput). After a few months, he was appointed Commanding Officer of 2 Rajput. The battalion was in Nowshera, Jammu and Kashmir along the Line of Control. It was a part of the 80 Brigade under the 25th Infantry Division. He commanded the battalion for about two years in Nowshera, before taking the unit to its peace location in Faizabad. The tenure started off in a tense environment - the Demolition of the Babri Masjid in December 1992, when the battalion was on the move to Faizabad.
