Starting May 30, the LGB capable Mirage 2000, which was deemed the best aircraft in the IAF inventory capable of optimum performance under the conditions of high-altitude seen in the zone of conflict, was used extensively. Armed initially with 250 kg "dumb" bombs, No. 7 Squadron led by Wg Cdr Sandeep Chabra, struck over three days infiltrator positions in Muntho Dhalo, Tiger Hill and Point 4388 in the Drass Sector. The receding snowline in June laid bare the hitherto camouflaged Pakistani positions, opening them up to non-stop day and night attacks by the Mirage 2000 and, subsequently, all aircraft.
