British tanks put out of commission while fighting in the Libyan battlefields are “ferried” across desert wastes to central repair shops on special heavy trailers. Although the tanks are hardy cruisers, they frequently become immobilized since there are many things that can go wrong. The huge trailer is equipped with two stout steel runways hinged at the back, which can be lowered for hauling the tank aboard. Both the truck and trailer have heavy tires designed for desert travel.
