Indonesia is the 4th most populated country on earth. Its territory straddles across thousands of islands. It needs to continue to expand its military's capabilities if it wants to keep its interests safe.
Population: 273.1 million
Defence Budget: 8.9 billion
Total Personnel: 800,000
Although the Indonesian army isn't as large as other counties with big populations, it is surprisingly well equipped. It's equipment levels and selection is similar to European nations. With 103 upgraded Leopard 2s and an upcoming delivery of hundreds of MMWTs (18 currently in sevice) the Indonesian Army has a some capable and modern tanks. It could've purchased more MBTs, however due to the terrain found in the Indonesian Archipelago lighter tanks are preferable. It also has an assortment of armoured vehicles. Most of the older APC/IFVs are being replaced with new ones.
The Indonesian Air Force is relatively small force. But just like its army, it is relatively modern across the board. Its main fighter is the F-16, it plans to order more F-16s soon. These will be the F-16V Block 72 variant, the latest and arguably best F-16s made yet. The other heavyweights in Indonesia's Air Force include the SU-27 and SU-30. Strangely the Indonesian Air Force plans to acquire SU-35s along with the F16s. There are also rumours which suggest that Indonesia may pursue F-35s. Indonesia's choice will end up shaping its relation's with China and the USA. If they choose the F-35s then they will have a huge boost to their capabilities, however it may cause a rift with the Chinese and drive Indonesia even closer to America. All in all the Indonesian Air Force is small, relatively modern, well trained, yet split between Russian and American hardware. Indonesia does have the capability to use both, however they must ensure that they do so in the right manner. Otherwise it will become a mess like some Middle Eastern Air Force's.
Armed UAVs: 2
Attack Helicopters: 16
Indonesia's Navy is its most important branch of the Armed Forces. Due to being a nation which spans a massive archipelago Indonesia needs a strong navy. Indonesia's navy has 5 submarines, 24 corvettes and 7 frigates including the new Martadinata-class. These are supplemented by over 150 patrol boats. Overall Indonesia's navy is fairly modern and is being driven forward with domestically produced ships. If Indonesia continues to further expand its navy, it may very well become a naval superpower.

Modern land equipment
A growing modern navy
Better training than most of its neighbours
Air Force is too small
Lack of carriers, which could be useful for operations across the archipelago
Tendency to buy both Russian and American fighters can be a troublesome choice
