This is the Academy 13255 kit in 1/35 scale, of the ‘American M18 Hellcat’.
History
It was the fastest armored vehicle in the American defense inventory of the 20th century. The speed was attained by keeping armor to a minimum, no more than one inch thick and roofless, open-top turrets (a standard design feature for all American fully tracked tank destroyers of World War II) and by powering the relatively small vehicle with a radial engine originally designed for aircraft usage.
The Hellcat, along with the M4 Sherman-based M10 tank destroyer and the highly effective, 90mm gun-armed M36 tank destroyer, provided American and Allied forces with a respectable mobile anti-tank capability against the newer German armored types.
