The portable green coloured 'morchas' will house one armed security personnel who could counter any firing coming from outside while keeping himself safe.
The Central Industrial Security Force (CISF), which secures the Delhi Metro network against any terror and attack like threat, has placed six such defence infrastructure at three prominent stations, in the preliminary stage.
While four bullet-proof 'morchas' have been stationed at the Rajiv Chowk Metro station, one each has been placed at the Malviya Nagar and Saket Metro station.
200 such 'morchas' will be placed in all the 134 Metro stations that the paramilitary guards in Delhi and the national capital region. Big stations with multiple entries will have more than one such fortified defence.
"The 'morchas' give our personnel better protection and strategic edge to manoeuvre himself during an attack or emergency," CISF spokesperson Hemendra Singh said.
200 such 'morchas' will be placed in all the 134 Metro stations.
The new defence gadget is stationed on wheels which makes it movable while protecting the security personnel and also has proper slots for the trooper to position his or her INSAS rifle, directed towards the entry.
The 'morchas' have been procured by the Delhi Metro Rail Corporation (DMRC) on the requirement made by the CISF after a security analysis favoured such an arrangement, security sources said.
