I was reading on the Pasubio Division supporting the German Advance on Petrikova. It seems on September 18th, 1941, while crossing the Vorskla River on a pontoon bridge, the Russians opened fire on the pontoon boats and damaged the bridge. So far, this seems rather ordinary. Now for the fun part. The unit firing on the Italians was a concealed and noise suppressed tank in a hull down position. The spotting for the tank was being conducted by shepherds who moved their sheep around until they spelled out letters to a circling Soviet aircraft overhead who radioed the information to the tank. Once the Italians figured out what the shepherd was up to, he was captured, the tank spotted and dealt with through an air strike.
So what I want to know is, did the Soviets indeed have "silencers" for their tanks? What tanks would/could have such a device? How on earth do you make a scenario using shepherds and their flocks as a forward observer (for any rules)?
Anyway, I was amused by this small tidbit and wanted to pass it along.
