Tigers At Minsk
Tigers at Minsk is a set of WWII rules designed for 10mmm figures on 4 inch hexes. The author writes:
These rules are specifically designed for WWII tactical games to be played in a small area (3′ x 2′ or slightly larger) using 4″ hexes. Units represent individual infantry sections, support weapons and vehicles. Most of the scenarios presented here use a gaming space that is 8 hexes wide by 6 hexes deep if using a 4″ hex with the hex grain running sideways (see scenario maps). The equipment lists and scenarios relate to the east front circa 1943 / 44 and have been developed using Kallistra hex terrain and Pendraken’s 10mm figures.
