After Belize achieved independence in 1981 the United Kingdom maintained the deterrent British Forces Belize in the country to protect it from invasion by Guatemala. During the 1980s this included a battalion and No. 1417 Flight RAF of Harriers. The main British force left in 1994, three years after Guatemala recognised Belizean independence, but the United Kingdom maintained a training presence via the British Army Training and Support Unit Belize (BATSUB) and 25 Flight AAC until 2011 when the last British Forces left Ladyville Barracks, with the exception of seconded advisers.[4] The BDF Maritime Wing became part of the Belize Coast Guard Service in November 2005.[5]
