The command, discipline, administration, and all other affairs pertaining to the Antigua and Barbuda Defence Force are under the control of the Antigua and Barbuda Defence Board. The Defense Board may assign additional responsibilities to the Antigua and Barbuda Defence Force. By order of the Defense Board, the Antigua and Barbuda Defence Force may be organized into units or other military entities.

The operational use of the Force is under the control of the Chief of Defence Staff of the Antigua and Barbuda Defence Force. Regulations issued by the Governor-General govern this duty. The Prime Minister can, nevertheless, give instructions to the Chief of Defence Staff about the operational employment of the Antigua and Barbuda Defence Force within the nation in situations when the Governor-General has not issued directives. The Prime Minister has been given this power in order to maintain public safety and order as they see fit. The members of the Defence Board are: (a) the Prime Minister, who shall serve as chairman, ex officio; (b) the Minister responsible for Defence and National Security; (c) any other Minister that the Prime Minister designates; (d) the Chief of Defence Staff, ex officio; and (e) the Permanent Secretary, in the Ministry responsible for Defence, or such other public officer that the Prime Minister designates. Any member of the Defence Board may be nominated by the chairman to preside at any meeting of the Defence Board at which the chairman is not present. The nomination may be general or specific to a particular event.

The Permanent Secretary or any person that the chairman designates to carry out the duties of Secretary at any Defence Board meeting in the case of the Permanent Secretary's absence or incapacity to do so, shall be the Secretary of the Defence Board. The Defence Board may; (a) regulate its operations, how it will carry out its duties, and the responsibilities of its members; (b) delegate any powers or responsibilities of the Board to any member of the Board by notice published in the Official Gazette; (c) consult with any non-members it deems appropriate, including officers commanding units of the Force, on matters pertaining to their units, and the officers shall attend such consultations.
