Regional Military Command

The Armed Forces' military regions are known as Kodam. Their organization was established by General Sudirman, following the model of the German Wehrkreise system. The system was later codified in Surat Perintah Siasat No.1, signed by General Sudirman in November 1948.

The Army's structure underwent various reorganisations throughout its early years. From 1946 to 1952, the Army was organized into combined arms divisions. These were consolidated in 1951, and then dissolved in 1952. From 1952 to 1958-59, the Army was organised into seven Territorial Armies (Tentara & Teritorium) composed of regiments and independent formations at battalion level and below. In August 1958, the Indonesian Army reconsolidated its territorial organization. This created sixteen regional commands, which retained earlier divisional titles; the Siliwangi Division, for example, became Kodam VI/Siliwangi.[1] The Kodam were subdivided administratively into Areas (the former territorial regiments), Districts (the former regimental battalions) and District Sectors, and operationally composed of a number of speciality battalions and in some regional commands, an infantry brigade.

A reorganisation in 1985 made significant changes in the army chain of command. The four multiservice Regional Defence Commands (Kowilhan) and the National Strategic Forces Command (Kostranas) were eliminated from the defence structure, re-establishing the Regional Military Commands (Kodam) as the key organisation for strategic, tactical, and territorial operations for all services. The 16 regions were reduced to just 9.[2] The chain of command flowed directly from the ABRI commander in chief via the Chief of Staff of the Army to the ten territorial commanders, and then to subordinate army territorial commands. In 1999, the number of regions grew to 10, and today, there are around 15 in active operation.

The territorial commands incorporate provincial and district commands each with infantry battalions, sometimes a cavalry battalion, artillery, or engineers. The number of activated infantry brigades is increasing.[3] Some have Raider battalions attached.

Each Regional Command is led by a general officer of Major General rank, assisted by a Chief of Staff, a billet of a Brigadier General. These are subdivided into the following territorial formations:

• KOREM: Military Area Command (Covering large areas or residencies) - further divided into 2 type, A and B, commanded by a Brigadier General and Colonel respectively
• KODIM: Military District Command (City or Regency level) - further divided, into 3 type, independent, A and B, commanded by a Colonel, Lieutenant Colonel and Major respectively.
• KORAMIL: Military District Command Sector (Kecamatan level) - further divided into 2 type, A and B, commanded by a Major and Captain respectively.
• BABINSA: Village Subsector Command (lit. Village Trustees Officer) (Desa/Keluhuran level) - usually Babinsa are Senior Bintara or Non-commissioned Officer although there are also senior Enlisted men.

In addition, each of the Kodam has a Regional Training Regiment is also present in for the training and education of enlisted personnel and non-commissioned officers in their area of operations.
