evidence: Heightened concerns about Depsang come from an earlier intrusion in this sector in 2013, when the PLA set up positions 19 km into the Indian side of the LAC and triggered a face-off that took three weeks to resolve. [...] The Depsang plains lie south of DBO in a strategic area that the military calls Sub-Sector North (SSN). DBO is the country’s northernmost outpost where India operates an advanced landing ground to support its forward military deployments. "Depsang is more of a pressure point as the PLA’s reported deployment in forward areas has disrupted the Indian Army’s patrolling pattern. It has become more time consuming for the army to dominate the LAC. But as long as talks are on there is hope for a mutually-acceptable solution to the dispute," said Lieutenant General Vinod Bhatia (retd), a former director general of military operations.
