Here begins a series of blog entries, extracts with commentary from items as seen at the latest edition of the DEBKAfile news letter.

That battle for Mosul continues unresolved. ISIL as usual being ruthless but also very canny and resourceful!

"ISIS rigs cardboard tanks in Mosul to deceive US pilots"

3 December.

"The Islamic State buttressed its Mosul defense over the weekend by scattering tanks and APCs across the city around strategic locations. But, according to Western military sources, the tanks were fakes made of cardboard, for the purpose of misleading the US planes and drones attacking them. The fake vehicles were constructed with great cunning and hard to distinguish from real tanks and APCs"

A metal frame over the body of a small vehicle. Then canvas or some sort of covering over the frame. From the air this will fool? And can be moved around and displaced as needed or as part of a further deliberate deception plan!
