This is a 1:35 M18 Hellcat US Army Gun Motor Carriage from Academy Plastics. It's for experienced modelers. The M18 Hellcat is not really considered a tank, but is designated as a gun motor carriage. This means it is mobile artillery intended more for infantry support. The M18 was used primarily during WWII. It was quite fast for a tracked vehicle, with a top speed of 55mph. It was powered by a 9-cylinder radial engine producing 340 or 400hp. A total of 2,507 M18s were produced between July 1943 and March 1945.
