This year, the Mujahideen adopted a new strategy by severing the line of communication that facilitated the build-up of supplies and troops in the Siachen, Leh and Kargil areas during the summer. This objective was achieved by the Mujahideen occupying the higher strategic positions along Kargil, Dras, Batalik and Turtuk.From the height of nearly 12,000 to 14,000 feet, the Mujahideen practically dominate the Kargil, Leh and Siachen line of communication. This has made it hard for India to augment supplies in Leh and Siachen. To clear these heights from Mujahideen occupation through ground operations was difficult. As an alternative, India deemed it expedient to open up a new route from Pathankot to Manali, Limba, Leh and Siachen. This is a long, circuitous and difficult road, but it may help India to reinforce its troops in Siachen and Leh - provided this line of communication is also not interrupted by the Mujahideen. India deemed it a strategic compulsion to use armed helicopters to flush the Mujahideen out of the Kargil and Dras areas. This has resulted in the violation of the LoC as bombs landed in Pakistani territory with attendant hazards. Indian migs violated Pakistan air space, and two of them have been shot down by Anza missiles (developed by Dr A.Q. Khan).
