Invisible laser walls to guard 198-km Indo-Pak border in J&K
A 'Made in India' invisible laser technology called 'Kavach (KVx)' will be used to guard the 198-km India-Pakistan border in Jammu and Kashmir to detect intrusions and relay information to the nearest BSF post for action. "Laser walls, because of their beams, were visible. And the terrain and alignments (in the region) were a problem," said ex-Inspector General of BSF.
