UsefulNotes/{{Indonesia}}'s military force is called the TNI (Tentara Nasional Indonesia, Indonesia National Armed Forces). The branches are TNI Angkatan Darat (Army), TNI Angkatan Laut (Navy) and TNI Angkatan Udara (Air Force). They have several spec ops groups, most notably Kopassus (Komando Pasukan Khusus).

They've also participated in the UNPROFOR. They also have a marine corps, which is attached to the Navy. They're pretty well-equipped, operating BTR-80 APCs, the BMP-3 IFV and PT-76 amphibious tanks, however they're relatively unheard of compared to the other branches.

The TNI reports to the President through the office of the Ministry of Defense (formerly the Department of Defense until a 2010 reform of the cabinet). It was established on October 5, 1945 - at the height of the National Revolution.

Officially, Indonesia cannot join any military alliance due to the constitution, in practice, Indonesia still hosts and joins semi-regular military exercises with her neighbor and major players, with limited security cooperation against piracy and terrorism.

!! The Army

!!Equipment
Indonesia has long histories with both Russia/former USSR and the US, and as a result operates equipment purchased from both:
* The standard service rifle is the [=SS1=] (Senapan Serbu = assault rifle), a licensed copy of the Belgian FN FNC carbine made by the government corporation (BUMN) HK G3, M16 and 5.56 mm AK variants are also used, the latter oddly enough are more often seen in the hand of cops guarding [=ATMs=] while they're being filled. The M16 is still the most widespread assault rifles in use. The spec ops units often use M4, HK [=G36=], Steyr-Mannlicher AUG, and [=HK416=]. There are also some Galil assault rifles in use, though it seems nobody will admit where they came from. Recently, PT Pindad started manufacturing an assault rifle called the [=SS2=], which looks like an M16 with AK gas block (despite the looks, it is actually a heavily modified FNC design rather than M16), reversed front sight and slightly different detachable carrying handle.
* As for sniper rifles, they mostly use the Remington 700, HK [=G3SG1=] and Galil-Galatz. The special forces also use the PGM Hecate II, a .50 caliber French bolt-action rifle.
* Much of their armor is composed of lighter vehicles such as light tanks and [=IFVs=], as the country's terrain is not conducive to operating heavier [=MBTs=] . They also operate BTR-80 and BTR-50 armored personnel carriers and V-150 Commando and M113 IFV-s. Early Cold War-era British armored cars also appear occasionally. Land Rover Defenders and Singapore's Flyer are used by both the police and the army, sometimes mounted with anti-aircraft guns or Singapore's CIS automatic grenade launchers. The South African Casspir is used by the police. As for local designs, Pindad also has started producing the Pindad Panser (meaning armored car), a rather plain looking APC. Some [=BMP-2=] and [=PT-76=] are in use by the marine corps, as well as a small number of [=BMP-3s=]. They have also made several anti-riot vehicles. Recently, Marder [=IFVs=] have been purchased from the Netherlands, plus the nationally produced Pindad Panser Anoa APC series.
** Recently, TNI AD has also purchased German Leopard [=MBTs=], for the Kostrad, specifically the A4 model and its Revolution upgrade. The decision was questioned because Indonesian terrain isn't ideal for 60-ton [=MBTs=] like the Leopard 2:: Java has to many open terrain but primary staple is rice which is planted on muddy rice paddies, so open terrain is muddy; elsewhere either has limited open terrain or mountainous, to solve these problems a new medium tank is being made with Turkish assistance to adapt to the wide range of terrain the country has- the [[https://en.wikipedia.org/wiki/Modern_Medium_Weight_Tank MMWT]]- or (as Indonesians call it) the Pindad Harimau (Tiger; no relation to the German Tiger I of [=WW2=] fame)
* They have F-16 and Su-27 fighters (plus new Su-30MK2s), with Dassault Rafale and F-15EX recently ordered (cue ''VideoGame/AceCombat'' jokes). They also had A-4 Skyhawk and OV-10 Bronco ground attack crafts and BAE Hawk light fighters; the former was bought via a secret deal with Israel [[note]]To this day both countries do not have diplomatic relations [[/note]] and the latter three were bought for COIN operations in East Timor. The [=TNI-AU=] is the second military force outside of the US to operate the C-130 Hercules cargo planes and just recently procured the latest C-130J Super Hercules variant.
** As for their helicopter fleet, they operates several gunships in form of the older Russian Mi-35P Hind and the newer American AH-64E Guardian Apache, making them the second armed service to operate both Hind and Apache platforms after the [[UsefulNotes/IndiansWithIglas Indian Air Force]]. Their primary utility helicopter is the [=NBell=] 412, locally produced variant of Bell 412, that are armed with either locally licensed FN [=MAGs=] or [[GatlingGood M134 Minigun]], and has ordered a batch of 24 S-70M Black Hawk helicopters. The [=NBell=] 412 helicopter is also used by the National Police in addition of the military. The navy also owns several types of naval helicopters, mostly British, plus nationally made transports, including the aforementioned [=NBell=] 412 helicopters.
** Indonesia has a rare record of their F-16-s having accidents; rather worryingly, said accidents happened a total of 5 times in 3 decades.
* The police force is called Polri (Kepolisan Republik Indonesia). Regional units are called Polda (Polisi Daerah) for provinces, Polres (Polisi Resor) for cities, townships and municipalities, and Polsek (Polisi Sektor) for districts. Formerly a part of the Armed Forces, today the POLRI is a directly reporting agency under the direct control the Office of the President thru the National Police Commission.
* Local police forces (''Satpol PP'') are tasked for protection of cities and municipalities and also act in coordination with the national police. These local police forces are responsible to the Ministry of Home Affairs through their respective local governments.

!!Notable Units
* The Brimob (Brigade Mobil) is pretty much the Indonesian SWAT, only they're less specialized and often perform tasks commonly done by the normal cops in foreign countries. Founded in 1946, recognized by their light blue berets pushed to the left (common in the police unlike in the armed forces, whose berets are pushed to the right sans the Military Police), and organized as a full Corps with 4 national regiments and 32 regional regiments stationed nationwide.
* The Kopassus (Komando Pasukan Khusus, i.e. The Special Forces) have tales of rampant badassery throughout its ranks. Some of it even stray into the supernatural sometimes, the most famous being one tale where a Kopassus soldier shrugging off a sniper round to the temple in a live-fire exercise. Formed as a full division of 4 SF Regiments and one training center, recognized by their red berets given that its founder was an ex-Netherlands Army Special Forces operator.
* The KOPASKA or Naval Frogmen Unit, modeled on the Navy [=SEALs=] and with a similar recruiting policy (and have continued joint training with them as it was in the early days of its formation). Organized into three Battalion Combat Teams with 6 Teams per fleet command.
* Marine Force Recon (''Yontalfib'') is organized as a regiment of 3 special force recon battalions within the Marine Corps. Known for their violet berets.
* The Paskhas (Air Special Forces), actually the oldest, having been raised during the National Revolution, is a ground combat unit that is capable of operating on land, sea, and air for capture and defense of airfields and air installations. It also as an air defense role. They are more recognized by their orange berets. The PASKHAS are organized as a full corps with 3 divisions.
* The Army Strategic Reserve (Kostrad, founded by soon to be President Suharto, himself a veteran of the National Revolution, in 1962) serves as the elite national reserve service of the army and the armed forces. These active reserves also get a share in the new equipment and vehicles in service in the TNI-AD. They are recognized by their green berets. Also organized into a corps, these are formed into 3 infantry divisions, one intelligence battalion and one battalion combat team formed for combined arms operations.
** Suharto later becoming a dictator who served for 31 years in the presidential office is the OldShame of the unit, especially veterans who served under him when he was the founding commanding general from 1962 to 1965, when he was promoted to Chief of the Army after distinguishing himself in the events of the 30 September Movement attempted coup that very same year in the capital area.
** Another such old shame is the 2nd commanding general, vice-president Umar Wirahadikusumah (in office 1983-88). He served this capacity from 1965-1967 and had been involved in the anti-communist activities after the September failed coup alongside the corps he led. He was formerly the founding commander of Jakarta Command.
* The Presidential Security Forces (Paspampres), successor to the infamous Tjakrabirawa Regiment (in service 1962-65 and had been possibly the ones responsible for the 1965 coup) is the official presidential guard brigade of the armed forces, formed into 4 regiments plus other support units that serve the President, the Vice President, foreign guests, and former heads of state, the First Family and families of former Presidents and Vice Presidents. Identified by their ceremonial red shakos, blue peaked caps and scarlet dress uniforms on ceremonial events or blue berets during normal days and weekends. Formed by personnel seconded from the elite forces of the Armed Forces and formerly from the Police Mobile Brigade.

!!The Indonesian Military in Fiction

* In the original game in the ''Delta Force'' series, one of the campaigns has Delta Force operatives working to prevent a terrorist group from overthrowing the Indonesian government. Most actions that Indonesia's own military takes part in happen off-screen, but there is one mission where the Army does make an appearance as allies to the player. In that mission, the objective is for Delta Force and the Indonesians to work together to prevent the assassination of the President of Indonesia by making sure his limo survives a terrorist ambush.
** The multiplayer spiritual sequel ''Joint Operations Typhoon Rising'' features Kopassus as one of the playable military units.

* In ''Literature/TheTomorrowSeries'' it is heavily implied that they are the unnamed enemy invading Australia. It's also possible the enemy are UsefulNotes/ChineseWithChopperSupport, or perhaps an alliance of the two. This is never confirmed however.

* Indonesian armed forces are the player's opponent in ''AV-8B Harrier Assault'' game, a combination of combat flight simulator and RTS. The game has a hypothetical conflict scenario with a US Navy taskforce trying to liberate the East Timor island from Indonesian military presence.

* In ''Series/TheLastOfUs2023'', they briefly appears in the ColdOpen of Episode 2, trying to contain the first known Cordyceps infection cases in Jakarta. The mycologist they enlisted to study the cadaver of the infected declares that a cure is a lost cause and advising them to [[GodzillaThreshold level the entire city to the ground along with its citizens to prevent the further spread of the fungi]]. It is currently unknown whether the Indonesian military had carried out the deed or not, but whatever they did, it done little to halt the Cordyceps infection to the rest of the world.
