Oh, yes......, the Samson...... Another of the all things to all men variants! I saw a demonstration of the Samsons features and one part was firing a grappling hook to enable it to unditch itself from an otherwise unrecoverable position. The cable and grappling hook was fired off the vehicle to dig itself in some 60 or so metres ahead, which it duly did but unfortunately, no-one had thought to anchor the rear end of the cable to the Samson chassis. So off into the distance went the rocked fired grappling hook plus a long length of unwinding steel hawser and a still bogged down Samson had to be unbogged later by an older (and wiser crewed) Centurion AVRE that it was going to part replace. The Samson was then replaced by the CET, a Combat Engineer Tractor, something that could do the job.
