New Delhi, Feb 13 The Defence Acquisition Council (DAC) chaired by Defence Minister Nirmala Sitharaman on Tuesday approved the purchase of military hardware worth Rs 15,935 crore (almost $2.5 billion). These include procurement of Advanced Torpedo Decoy Systems (ATDS), light machine guns, assault rifles and sniper rifles. "This procurement will meet the operational requirement of the troops deployed on the borders. A concurrent proposal is being processed for the balance quantity to be procured under the 'Buy and Make (Indian)' categorisation," the Defence Ministry said in a release. The DAC also accorded approval for procurement of 7.4 lakh assault rifles for the three services. These rifles will be made in India under the categorisation of 'Buy and Make', through both Ordnance Factory Board and Private Industry at an estimated cost of Rs 12,280 crore, it said. In the last one month, to equip the soldiers on the border with modern and more effective equipment, the DAC has fast-tracked procurement of the three main personal weapons -- rifles, carbines and light machine guns. The DAC also approved procurement of 5,719 sniper rifles for the Indian Army and Indian Air Force at an estimated cost of Rs 982 crore.
