The M4A3 Sherman HVSS (Horizontal Volute Spring Suspension) served in WW2 and Korea as well serving during many of the Middle East wars. During WW2 the US Army had fitted a number of Shermans with flamethrowers including the M4A3 105mm. Nine of these vehicles were put together from 26 flame tanks at the start of the Korean War. Together they formed a platoon of flame tanks known as the "Flame Dragons". They saw combat on 15 September 1950 on Wo-mido Island.
