'O'Group: Wargames Rules for Battalion Size Actions in WWII 2021

In 'O' Group each player fields a battalion of troops under the command of the Battalion HQ. The battalion consists of a number of infantry companies, normally three, and will usually be supported by heavy weapons, guns and, of course, AFVs. This is a typical club-night sized game, although the rules easily and simply allow multiple players to field multiple battalions under a Brigade or battlegroup command if they wish. The command structure allows for each company having a company commander who attempts to maximise command and control for his company and battalion command who are attempting to influence the bigger picture. The standard tactical units in the game are the infantry platoon and gun or AFV platoon. That said, it is possible to operate heavy weapons, guns and tanks as single sections, so maybe a lone Tiger on the prowl.
