The regiment has a number of roles - primarily it is responsible for maintaining the internal security of Antigua and Barbuda, which is linked to providing assistance to the police in maintaining law and order. However, it is also responsible for providing the Antiguan contingent to peacekeeping missions overseas, often in conjunction with other countries in the Eastern Caribbean. In its previous incarnation as the Rifle Company, the regiment participated in the invasion of Grenada alongside the Barbados Regiment and Jamaica Regiment in 1983.

In December 2004, Baldwin Spencer, the Prime Minister of Antigua and Barbuda, announced that, as part of the reforms to the ABDF, the 1st Battalion, Antigua and Barbuda Regiment would convert from its current light infantry role into a marine role, enabling it to better support and serve the ABDF Coast Guard in its anti-drug and maritime security missions.^[1]
