The American M4 Sherman is the best known, most widely used tank of the Second World War. It is also the most controversial. Was it the all-American tank that won the war or a completely under-designed death trap? We go to the Isle of Wight Military History Museum, where Dave Arnold and his crew are about to try something no one else has ever done before. They are going to chop two destroyed Shermans in half to piece together one good one. If they can pull it off it will be a testament to the most revolutionary aspect of the Sherman’s design – American-style production engineering allowed for production on a massive scale. It will show just why the Sherman, despite its flaws, remains one of the most important tanks ever made; and one of the many reasons why the Allies won the War.

Dave Arnold and his crew at the Isle of Wight Military History Museum are set for a real challenge. They’ve rescued a rare 1945 COMET Tank from an Army firing range. It’s been shot to hell and they only have four months to get it ready and running for the crowds at Tank Fest 2006. We’ll see tons of action in the shop as they tear it apart; overhaul the engine; strip, sandblast, paint and put it back together again. Along the way, we’ll find clues in the form of serial numbers and markings that retrace the war-time mission of tank and crew behind enemy lines; from the crossing of the Rhine to confrontation with the deadly Panzerfaust, and the final race for Berlin.

Featuring restoration of an Panzerjger Tiger - Elefant. One of the largest heaviest tank destroyers ever built, the Elephant was brilliant on paper and terrifying to behold. But in 1943, the Germans sent it into battle without having ever tested it. Under fire, the massive monster turned out to be a sitting duck for courageous Soviet fighters who learned they could disable it with a simple Molotov cocktail. The Elephant is possibly the rarest surviving tank from World War 2. Only 90 were ever built and now only two are thought to exist. At the US Army Ordnance Museum, you will see a crack team restore a rusted beat up machine that has been left on the sidelines since 1944.

Featuring restoration of an M-24 Chaffee Tank. In this episode, you'll meet Joe Garbarino, CEO of Marin Sanitation, a massive garbage and recycling business in San Rafael California. Joe's true passion is his collection of military vehicles. And one of his pride and joys is the M-24 Chaffee. Fast, dependable, armed with an excellent 75 mm gun, some historians say this was the best light tank of World War 2. Every year on July 4th, Joe and his team join a local Independence Day parade. But this year, somewhere inside its massive hull, the M-24 has sprung a leak - and the leak might keep it out of the parade.
