For those SWJ readers who think that IS does not drive on an intelligence driven operations concept...their attack cells use a form of OPSEC tradecraft that resembles that of spy cell tradecraft......think again.....reference today's Brussels airport bombing....we saw this as far back as 2003 in Iraq and it has not changed since 2003.

Cells operating by the book if one gets neutralized the other one gets into action to divert attention from the first cell.....and what has come out of the Brussels major arrest....not a single use of any form of communications outside of face to face....defeats every time any form of major communications surveillance operations.

Defeating IS cells has always been about the heavy use of police and security services to defeat them using their own tactics...not through the use of high tech which we seem to think is the be all end all.
