Universal conversion kit of an M4A3E2 Jumbo Sherman. Will convert most 1:56 models. Modeling experience required. In 1944, combat engineers in Pattons 3rd Armored created a "breakout" tank to lead their armored columns. With extra layers of hull armor, and an enlarged turret, the M4A3E2 Jumbo was a standoff tank, able to take multiple hits from German Anti-tank guns and armor, allowing the rest of the armored column to return fire.
