Road to Hell is a set of free wargames rules for WWII skirmishes. The author writes:
1.0 SCALE
This is a skirmish game so one miniature represents one man and one model vehicle is one vehicle. One centimetre corresponds to around 2 metres and a turn represents 10-20 seconds of real time.
2.0 YOU WILL NEED…
You’ll need a couple of units or squads (one per player) of around 8-15 miniatures each to play Road to Hell (for more details see the Army lists), a few six-sided dice (hereafter referred to as d6) a ruler or tape-measure (all measurements are in cm) and a minimum recommended playing area that measure 80x80cm (30×30 inches) for 28mm figures and 60x60cm (2×2 feet) for 20mm figures. Considering that these are small skirmishes, scenery is very important. Avoid battles in open ground as they will be very lethal and not particularly satisfying
