The Sherman tank’s siren.

Did you know the Sherman tank has a siren? Provided by the Mars Signal Light Company of Chicago, the siren is a quick and easy way for primitive communication with those immediately outside the 30-ton armored behemoth. A quick blast on the “horn” could mean, “Move” or “Watch out” or, in our case, it means, “Heads up, we’re firing.” Mars made lights and sirens before the war and still are in business today as Tri-Lite, making warning lights for ships and docks, warehouses, and emergency vehicles. They also still make sirens and those pesky back-up warning systems for big trucks.
