The deployment has been made after security agencies carried out an analysis of the training centres, administrative offices and other facilities of the Research and Analysis Wing (RAW), Intelligence Bureau (IB) and the Aviation Research Centre (ARC) in the country and it was felt necessary to secure them in view of possible threats to them, sources said.
The troops to guard these facilities have been drawn from the Sashastra Seema Bal (SSB), a border guarding force which is tasked to man India's border with Nepal and Bhutan.
The security squad will not only control the access to these facilities but also provide a quick reaction team of commando-trained personnel who will respond to any emergency.
The personnel, posted at these centres, have also been trained in unarmed combat and specialised weapon firing, they said.
