Indonesian Military

The Indonesian National Armed Forces (Indonesian: Tentara Nasional Indonesia, TNI; formerly Angkatan Bersenjata Republik Indonesia, ABRI) in 2009 comprises approximately 432,129 personnel including the Army (TNI-AD), Navy (TNI-AL) including the Indonesian Marine Corps (Korps Marinir) and the Air Force (TNI-AU).
The Indonesian Army was formed during the Indonesian National Revolution, when it undertook a guerrilla war along with informal militia. As a result of this, and the need to maintain internal security, the Army has been organized along territorial lines, aimed at defeating internal enemies of the state and potential external invaders.^[2]
Under the 1945 Constitution, all citizens are legally entitled and obliged to defend the nation. Conscription is provided for by law, yet the Forces have been able to maintain mandated strength levels without resorting to a draft. Most enlisted personnel were recruited in their own home regions and generally trained and served most of their time in units nearby.
The Army is by far the largest part, with about 328,517 active-duty personnel, compared to around 74,963 in the Navy and 34,930 in the Air Force.^{[citation needed]}. The Indonesian armed forces are voluntary. The available manpower fit for military service of males aged between 16 to 49 is 52,000,000, with a further 2,000,000 new suitable for service annually^[3]
Military spending in the national budget was widely estimated 3% of GDP in 2005,^[3] but is supplemented by revenue from many military-run businesses and foundations. The Indonesian Defence force personnel does not include members of law enforcement and paramilitary personnel such as POLRI (Indonesian police) consisting of approximately 540,000 personnel, BRIMOB (police mobile brigade) of around 39,000 armed personnel, the Civil Service Police Unit, MENWA (university student regiment) 26,000 trained personnel, and HANSIP (civilian defence), number unknown.
