All aircraft operated at an altitude of 9-10,000 metres, (~30-33,000 feet above sea level), diving when required and pulling out well out of MANPADs range. The low number of airstrips for take off and landing of the flights also constrained the regularity and efficiency of the attacks. Despite this, there were hundreds of sorties on the intruders with no further material or personnel casualties enabling a gradual takeover of the mountain posts by Indian troops. According to the IAF, the "air strikes against the Pakistani infiltrators, supply camps and other targets yielded rich dividends."
