Battlefront features the M4A3 HVSS for Flames of War
Battlefront takes a look at their M4A3 HVSS tank in their latest article for Flames of War.
From the website:
As further refinements were made to the Sherman design, the Horizontal Volute Suspension System (HVSS, for short) was incorporated into the M4A3 (105mm). This made it much easier to replace damaged road wheels and the new wide track improved the tank’s off-road performance. Together this gave the M4A3 (105mm) HVSS a much improved ride and far better flotation over soft ground.
