Good news, IMHO -- if they're dug in, they're unlikely to move. Our guys know where they are, and can call in precision strikes on the locations.
If the terrorists are "dug in" and a C-130 is called in to target that position, the terrorists will then have to be "dug out" from under a lot of rubble.
Might have missed this but can we blow up "holy" sites? Those will be their last place of refuge.
