The AVRE could also be equipped with numerous other attachments, such as the Small Box Girder bridge, which was carried at the front of the tank and laid across ditches or narrow rivers up to 30 feet wide, and the Canadian Indestructible Roller Device (CIRD),[58] which was used to protect the tracks of a tank from mines. It could also carry fascines, which are large bundles of wood carried on the front of the tank and dropped into trenches to help the Churchill cross over them, devices to place explosive charges against obstacles, and bobbins: massive reels of canvas on drums that were unrolled in front of the Churchill to help it over soft terrain. They were used during the invasion of Normandy to help the Churchill over soft sand,[55] and also served to leave a trackway for following vehicles
