Según la wikipedia:
«During and following the five-day Second Battle of El Alamein artillery barrage that commenced on the night of 23 October 1942, six squadrons of Hurricanes, including the 40 mm (1.57 in) cannon-armed Hurricane Mk.IID version, claimed to have destroyed 39 tanks, 212 lorries and armoured troop-carriers, 26 bowsers, 42 guns, 200 various other vehicles and four small fuel and ammunition dumps, flying 842 sorties with the loss of 11 pilots.»
No sé si la información es precisa o no (mis conocimientos de la guerra aérea son demasiado superficiales), pero es probable que el valor de bombardeo táctico intente reflejar este uso de los Mk.II.
