The following is the rules as endorsed by the AZW mod team. These do not have to be used but are the advised rule set, may change over time as testing progresses.
One primary difference in these events (BAC events specifically) is that all regiments are required to accept the leadership of a General who will usually be a trusted regiment leader. This general shall command that team through whisper on teamspeak. You must follow his orders, signing up to a BAC endorsed event is taken as an agreement of such. This also applies to the Zulu Amabutho (regiments).
