Just finished putting together a 15mm Matilda II Scorpion from Battlefront (Flames of War). The Scorpion was an on battlefield creation designed to face the endless minefields of the Western Dessert. Basically a wooden frame was constructed in front of a normal Matilda II, which supported a rotating flail of metal chains designed to hit the ground and explode any mines. It also had a capability of marking with chalk channels behind it to show following troops the lane cleared.
Its a nice figure and will support my 8th Army greatly against the evil DAK!!
