In Belize, the Belize Defense Force (BDF) is responsible for external security but also provides some support to civilian authorities; it has limited powers of arrest within land and shoreline areas, while the Coast Guard has arrest powers and jurisdiction within coastal and maritime areas; the BDF traces its history back to the Prince Regent Royal Honduras Militia, a volunteer force established in 1817; the BDF was established in 1978 from the disbanded Police Special Force and the Belize Volunteer Guard to assist the resident British forces with the defense of Belize against Guatemala

the British Army has maintained a presence in Belize since its independence; the presence consists of a small training support unit that provides jungle training to troops from the UK and international partners (2025)
