Yaldor Sub Sector was the scene of some of the major infiltration by Pakistani Northern Light Infantry battalions and some of the major battles of Kargil War were fought here. The sub sector basically covers Yaldor, a small village in the Indus river basin in the Leh district of Ladakh in India, and Yaldor nullah. The village located in the upper reaches of the mountains near the Line of Control that divides the Indian- and Pakistan-administered Kashmir, the village abuts the Yaldor nullah. The area was a focal point during the Kargil War because of its strategic location between Kargil, Leh and Baltistan. Only a few shepherd families live in Yaldor village, they spend their summers here and then spend their winters in Garkhun, taking their livestock with them. One of the shepherds from Garkhun, Tashi Namgyal, who was looking for his missing yak was the first to report about infiltrators from Pakistan on 3 May 1999 to Indian Army. The village has an army patrol base, which was set up in 1997 even before the Kargil infiltration of 1999. As of 2019, the village is out of bounds for tourists.
