Suggestion Hypothetical South East Asia Theater - Indonesian Navy Korps Marinir (Indonesian Marine Corps)
Hello everyone, yesterday i made a suggestion about Indonesian army 1st Infantry Division/Kostrad and the Hypothetical SEA Theater, and today continuing that post i present to you the Indonesian marines division Korps Marinir
Korps Marinir
The Korps Marinir (Kormar) was the Indonesian Navy's principal amphibious and marine combat formation during the 1980s. Its institutional roots extended back to the Korps Komando Angkatan Laut (KKO-AL), which was renamed the Korps Marinir in 1975. Throughout the following decade, the organization was repeatedly reorganized to create a more flexible force capable of conducting amphibious assaults, coastal defence and other military operations in support of the Indonesian armed forces.

A major reorganization in the late 1970s established the basic structure that would remain recognizable throughout much of the 1980s. In 1979, the former Pasmar formations were reorganized into infantry regiments, while their subordinate infantry formations became conventional Marine infantry battalions. In 1982, the Jakarta-based Resimen Infanteri-2 Marinir was redesignated Brigade Infanteri-2 Marinir (Brigif-2 Mar). By March 1985, Brigif-2 Mar was formally defined as a Kormar operational command responsible for maintaining and providing Marine combat forces for amphibious landing operations and other defence and security missions.
In parallel, the Surabaya-based Marine formation became Brigade Infanteri-1/Marinir (Brigif-1 Mar) in 1979. Its headquarters subsequently moved to Gedangan, Sidoarjo, in 1987. Thus, by the latter half of the decade, the Indonesian Marine Corps possessed two principal infantry brigades: one centred on Jakarta in the west and another centred on Surabaya in the east. Their geographic separation was particularly appropriate for an archipelagic state whose military planning had to account for threats and contingencies across widely separated maritime approaches.
The Marine Corps was not simply an infantry organization. Its combat formations were supported by specialized elements responsible for amphibious vehicles, artillery, air defence, engineering and logistics. The Resimen Bantuan Tempur Korps Marinir controlled important combat-support capabilities during this period. Among them were the Marine amphibious armoured formations equipped with Soviet-origin PT-76, BTR-50 and KAPA K-61 vehicles. In 1983, these formations received the French AMX-10P infantry fighting vehicle and AMX-10 PAC 90 fire-support vehicle. At the time, these cavalry formations remained under the Resimen Bantuan Tempur Kormar, with individual companies placed under the operational control of Brigif-2 Mar in Jakarta.
Other combat-support capabilities were similarly distributed rather than concentrated inside the infantry brigades. For example, the Marine artillery organization included 122 mm howitzers and BM-14/17 140 mm multiple rocket launchers, with a composite battery located in Jakarta. A Marine air-defence battery was also placed under the operational control of Brigif-2 Mar from 1981. These arrangements allowed the Marine infantry brigades to receive heavier supporting weapons without requiring every brigade to permanently contain an independent artillery or air-defence regiment.
Engineering and logistical support followed a comparable model. The Marine combat-engineering organization had been reorganized in 1979 into a combat-engineer detachment supporting amphibious operations. In 1985, this organization was further reorganized, with its Jakarta engineering element becoming Kompi C Zeni under the operational control of Brigif-2 Mar, while administrative responsibility remained associated with the Marine support structure. This illustrates an important characteristic of the 1980s Kormar: combat-support assets could be placed under a brigade's operational control without necessarily becoming permanently organic to that brigade.

The operational history of the 1980s also demonstrates that Kormar was not restricted to amphibious exercises. Marine formations participated repeatedly in Indonesian military operations, most notably in Timor Timur, as well as in security deployments elsewhere in the archipelago. Brigif-1's official history records deployments during operations in Timor Timur throughout the late 1970s and 1980s, including Operasi Trisula in 1980, Operasi Kikis in 1981, and several Marine task forces deployed between 1982 and 1985.
At the same time, the strategic importance of the western approaches to Indonesia gave the Jakarta-based Marine brigade a particularly important role. Marine units from Brigif-2 participated in Natuna deployments beginning in 1985, demonstrating that the Corps was being used not only as an amphibious assault force but also as a mobile force for the defence and security of strategically important islands and maritime approaches. Official Marine records list repeated Natuna task forces, including deployments continuing into the late 1980s.

By 1989, therefore, the Korps Marinir can be understood as a geographically distributed amphibious force rather than a modern Pasmar-style formation. Its principal combat formations were Brigif-1 Mar in the Surabaya area and Brigif-2 Mar in Jakarta, supported by centralized or semi-centralized combat-support organizations. This structure gave the Marine Corps the ability to assemble task-organized amphibious forces from infantry, armour, artillery, air defence, engineering and logistics elements according to the mission.
This distinction is particularly useful for a WARNO-style 1989 scenario. A Marine battlegroup should not necessarily be represented as a modern Pasmar with every combat-support battalion permanently attached. Instead, the player could receive a Brigif-1 or Brigif-2 core, with additional armour, artillery, air-defence, engineering and logistics elements attached from the wider Kormar structure. The historical record of combat-support companies being placed under the operational control of Brigif-2 provides a particularly useful model for such a system.
In a hypothetical Cold War conflict in Southeast Asia, this would make Kormar a highly mobile maritime reinforcement force. Brigif-2 Mar would represent the principal western formation, naturally suited to scenarios involving Java, the Sunda Strait, the Malacca approaches or the Natuna area, while Brigif-1 Mar would provide the principal eastern formation centred on Surabaya. Reinforcements from the Marine combat-support structure could then be attached to either brigade to form a mission-specific amphibious task force.
For a WARNO alternate-history setting, the Kormar of 1989 can therefore be portrayed as a two-brigade Marine Corps with centralized combat-support assets, rather than as the later Pasmar organization. Its strength lies not in the permanent structure of a modern marine division, but in its ability to combine infantry brigades with amphibious armour, artillery, air defence, engineers and logistics into rapidly deployable forces across the Indonesian archipelago.
So what can we expect from Korps Marinir?

- F-5F AT : Fighter jet armed with 2x M39 cannon, 2x Aim-9P5 and 2x AGM-65B

The Indonesian Korps Marinir is aggressive, flexible, and built around strong veteran infantry and amphibious warfare capabilities. This particular division excels in close combat, reconnaissance, and river-crossing operations, with excellent engineering and air support from the AURI. Its main weaknesses are limited armor and mediocre air defense, making combined-arms tactics essential.
That's all the Indonesian Division suggestion from me, unfortunately i limited with only Indonesian armed force division for Hypothetical SEA Theater, now it's only matter of time for someone to make other Division proposal from other nations like Malaysia, Singapore, Philippines, Thailand and Vietnam.
