Unlike it predecessor, the Colonial Guard is a full time reserve of the UNSC and is fully equipped to take engagement against an enemy. The equipment used by the CG is about the same as the other branch of the UNSC. Has per the constitution of 2575 all valid person must do a complete 2 years tour of duty in the CG or in any other branch of the UNSC. The CG is publicly funded by the colonies and in return the colonies as the colonies as the command of it CG complement.
