The Indian military's Subsector North (SSN) is east of Siachen Glacier, located between the Saser ridge on the Chinese side and the Saltoro Ridge on the Pakistani border. With regards to a two-front war for India, this area can provide for a linkage for Pakistan and China in Ladakh. The territorial wedge created by Depsang Plains-Karakoram Pass-Shyok Valley prevents this territorial linkup.
