Sorry to parade my ignorance, but what is "TTP"? And to my addled brain a prohibition on such a sensible [sensible, that is, if it works] tactics is a prime example of idiocy triumphant.
Sorry. TTP is tactic, technique, procedure.
I don't know enough about whether it works just to shoot an IED. I do know there are plenty of other methods of controlling IED detonations that the terrorists don't know about--and they're VERY effective.
