Falintil
Falintil (or FALINTIL) originally began as the military wing of the political party FRETILIN of East Timor. It was established on 20 August 1975 in response to FRETILIN’s political conflict with the Timorese Democratic Union (UDT).
The name FALINTIL is an acronym of its full name in Portuguese, Forças Armadas da Libertação Nacional de Timor-Leste. In English this translates as "The Armed Forces for the National Liberation of East Timor".
