Battlefront is featuring the Vickers 6-Ton tank for Flames of War in this latest article.
From the article:
During the Winter War only the Finnish 4th Tank Company saw action with their Vickers 6-ton tanks. The Finns ordered 32 Vickers 6-ton tanks in 1936. These were fitted with 37mm Bofors guns with a
co-ax machine-gun in Finland. A 9mm submachine-gun was also fitted to the hull.
