From the first week of April to the first week of May 2012, the Indian Army launched a massive summer exercise in the Rajasthan desert, involving over 50,000 troops and several hundred artillery pieces and infantry combat vehicles, as part of its efforts to shore up its battle worthiness on the western front, the border with Pakistan. The exercise, code-named "Shoorveer", was being conducted by the Jaipur-based South Western Command. This was the largest ever exercise conducted by Indian army since 1947. The collective training started with the honing of basic battle procedures and tactical drills.
