With the operational situation along the western front remaining volatile amid heavy exchanges of cross-border firing with Pakistani forces, the Indian security establishment is taking no chances in being ready for any contingency. Even as the Army and IAF airbases maintain top-levels of operational readiness, the Navy too is coming into action with a major exercise “Paschim Leher (western wave)” in the Arabian Sea from next week. Over 40 warships and submarines, backed by maritime fighter jets, patrol aircraft and drones, have already begun to amass on the western seaboard for the intensive combat manoeuvres, which include “cross-deployment” even from the eastern seaboard.
