Brothers Realism Mod (or BRM) is an in depth modification for Call of Duty: World at War which adds many new features along with a full class / squad structure for those people who like more realism in their game.
Loadout menus are fully customisable by the server admin, with up to 5 squads each with up to 14 classes. Each class can have a maximum of 5 different weapon / equipment loadouts to choose from.
