Not painful at all. It is the ultimate in stand off weapons. Can be fired from 10-20 miles away and the enemy never hears it coming. All you need is someone in the air or on the ground to paint the target, acquire the gps co-ordinates and bingo, they are gone. Much cheaper than using planes and their gps guided munitions. I believe some of these are being fielded in Afghanistan in the near future. Will be perfect for the kid of cross border strikes I think we are presently contemplating. If you start hearing about pakistani tribal area having a rash of premature suicide bomg explosions, you should not be surprised.
Go, baby, go !
