Tank A Day Adventure - Soviet IS-2: At the onset of Memorial Day weekend, I rode to the Collings Foundation's, newly-opened American Heritage Museum and spent some time photographing and obtaining information on each exhibit. Below is the 15th of these - the Soviet IS-2. The IS-2 was a WWII Soviet heavy tank that saw action in the later years of WWII, especially in the battle for Berlin. It weighed 45 tons and was powered by a 38.8L, 12-cylinder, 600 hp diesel. The tank had a crew of 4 and could travel 23 mph with a range of 150 miles. The tank had 4.72 in. front armor and a 122 mm cannon. Some 3,854 were built between 1944 and 1945 in either the Kirov factory or UZTM works. This particular IS-2 was built in 1944, was in the battle for Berlin (you can see the battle damage) and is the only one known to be in the U.S.
