A few years back I used to work at a place that was somewhat close (many miles away actually) from an NSG compound. They are said to have so many jammers (communication jamming devices) installed that our internet reception would always be patchy (at least that is the excuse IT department gave to us) and it felt quite annoying then. Now, I would say may they add 100 more jammers, if it helps their cause even a bit.
Looking at the commandos of the NSG at Mumbai (MARCOS, Army, Other Security Forces too) I was wondering what kind of a job it is that when everyone is running away from a place, these guys are storming into that place! Hats off to all of you out there.
