1. The CDL
This armored vehicle was deliberately given an inaccurate label- Canal Defense Light (CDL) – as a way to best keep it secret. It featured a powerful carbon-arc searchlight inside its modified turret. The light would provide the Allied troops with illumination during nighttime operations. It, however, would also produce a dazzling effect that would temporarily blind the rival forces. It was ingeniously designed to flood the light out of a fairly small incision in the armor to minimize the chance of damage by enemy fire. Of all Hobart’s Funnies, the CDL was the most furtively kept.
