Actually Komcad is different to Program 'Bela Negara' during RR administration. Both program are based on similar legislation, but each of them serve a different purpose in our national defense doctrine. According to the aforementioned bill/legislation (UU PSDN, Undang-Undang Pengelolaan Sumber Daya Nasional no 23 tahun 2019), there are three defense components:
1. Komponen Utama: Active TNI personnel
2. Komponen Cadangan: Reservist (part time TNI personel).
3. Komponen Pendukung: Polri, Civil Servant (PNS), BUMN employee (state owned enterprise), Menwa, Hansip, etc.
Komcad personnel will follow similar recruitment and training curicullum of TNI. They will receive 3 months basic training (Diksar), and for the officer recruitee they will get additional 3 months officer training.
Upon graduation, they will get military rank similar to the full time TNI personnel. In order to differentiate with those full time TNI unit, the Komcad will get .CAD after their rank and their name (i.e. Kopral Jono .CAD). Once graduated, they will be back to their civilian occupation/life, but they will be required to attend 30 days of compulsory refreshment training per-year. Additionaly, in the condition of national crisis (war, pandemic, natural disaster, social unrest) they can be mobilized by the President (and Governor) to support Komponen Utama (TNI).
Komcad will also have their own battalion. The battalion commanders and seniors officers will be appointed from active TNI officers. Majority of the Komcad will be assigned to TNI AD. However, there will be Komcad for TNI AL (Marinir) and TNI AU as well.
Why do we need Komcad?:
1. Zero growth policy for full time TNI (we have too many letkol, kolonel and brigjend). More part time TNI personnel will allow the organization to reduce unrequired position.
2. TNI salary/overhead take the most part of our defense budget. A bigger portion of part-timer will reduce pressure on the budget, and hopefully will improve personnel welfare/kesejahteraan that leads to professionalism.
MoD plans to recruit 125.000 Komcad within the next 5-10 years.
From how I understand from reading medias surrounding this policy, it seems like this is our version of US National Guards. This
Tirto.id article seems to suggest that Prabowo got the idea from his time in the US.
