Belize's closest military relations were with Britain. The BDF's rank structure, uniforms, equipment, and organization followed British models, and British regular forces in the nation provided much of the BDF's training.

BDF personnel also trained regularly in Canadian and United States facilities. On occasion, members of the BDF have served abroad in Mexico, Jamaica, El Salvador, and Colombia, usually as observers.

British forces in Belize were headquartered at Ladyville Barracks near Belize City. One battalion represented the bulk of the forces. This battalion was rotated through Belize at regular intervals, usually of six months, and was then replaced by another battalion. Other British military units rounded out this contingent, including one armored reconnaissance troop, one field artillery battery, and one engineer squadron. British air units consisted of one Army Air Corps flight and one-half of a squadron of the Royal Air Force, which provided airfield defense. Ships of the Royal Navy, sometimes with Royal Marines embarked, made regular stops at Belize, and in times of tension, Britain has shown a willingness to reinforce local forces with aircraft and other units as necessary.

Belize had bilateral defense treaties with Britain, the United States and Canada. All of these treaties concerned the provision of military training. Belize was not a signatory to any multilateral defense treaties as of 1991.
