That's a BIG no-no. Apparently that was a TTP last deployment, but it got stopped in a hurry. I'm not an EOD tech, so I couldn't tell you why, but I know that I'd probably end up getting fired very quickly if I did that on a patrol.
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.
