Free, relatively simple WW2 wargame. The basic game lasts 7 turns by each side; the expanded rules set doubles that. Many of the elements of wargames are presented here: zones of control, combat results table, movement and combat values, full strength versus half strength, terrain effects on movement and combat, turns divided into phases, and weather conditions for mud. A web-based version of the game also exists at https://oberlabs.com/b4m/
