This paper focused on the origin, structure and roles of the military of Belize, an arm of the state of the only English-speaking country in Central America. The key tasks that were undertaken by the Belize’s military were both external and internal. It is shown that Belize is the only country of the English-speaking Caribbean in which armed forces are used primarily for defense. This is so to deter the Guatemalan army from marching into Belize and to control the infiltration of its borders by illegal immigrants. However, Belize’s military has become increasingly involved in "police" operations, including the combating of drugs and maintaining domestic order, thus leading to a blurring of the roles of the police and the military, as well as the provision of relief during natural and other disasters. Finally, Belize’s military engaged in self-help programs and provided assistance to a number of civilian projects as a way of fostering improved civil-military relations.
