Platoon Action WWII Skirmish Rules
Platoon Action is a set of skirmish rules for WWII. The author writes:
Platoon Action is a skirmish-level game of World War II combat. Figure scale is one man to one man; ground scale is not exact, but about 1″ to 5-10 yards. Typically a player might control up to an infantry platoon (three squads of about ten men each; perhaps an HQ section); optionally supported by a few heavy weapons or vehicles. Although there are vehicle rules, it should be noted that these are primarily rules intended for infantry combat.
