Jakarta saw a large deployment of troops that the military described as routine readiness. On Wednesday, the Indonesian military confirmed that thousands of troops moving into the capital are operating under its lowest readiness tier — what the armed forces call Siaga 3 — a level Maj. Gen. Muhammad Nas, the TNI’s chief of public information, described as entirely normal, with soldiers simply barred from leaving their assigned cities, detikNews reported.
The deployment, which began Nov. 2 and involves nearly 21,000 sailors alone, has nonetheless fueled speculation about what Jakarta is preparing for. Nas brushed off any link to specific events, telling Kompas.com flatly: “No need to connect it with any issue.”
20,980 sailors, four phases, one chain of command
According to ANTARA, TNI Angkatan Laut has readied 20,980 personnel to reinforce security across DKI Jakarta, following a telegram from TNI Commander Gen. Agus Subiyanto, with all troops placed under the operational control of Kodam Jaya.
Phase one started Nov. 2 with 2,100 personnel drawn from units already in Jakarta — the Marine Corps, Koarmada I, Kodaeral III, and Kolinlamil. On Nov. 4, phases two and three brought in 5,740 more from outside the capital, moved by warships and overland, drawn from Koarmada II, Pasmar 2, the Navy’s aviation center, the naval academy, and bases across West Java, Central Java, East Java, and Lampung. A fourth tranche of 13,140 from Navy headquarters and Jakarta-area units sits on full standby at their barracks, ready to move at any moment, ANTARA reported.
Why the military says it is routine
TNI leadership insists the movement is readiness, not reaction. Brig. Gen. Donny Pramono, the Army’s information chief, told Kompas.com that TNI AD “constantly strives to maintain the readiness of units and personnel in facing every situational development,” framing the deployment as part of the military’s duty to defend sovereignty and protect the nation under Law No. 3 of 2025 amending the 2004 TNI law. Readiness, he said, is also a deterrent against threats to the capital. Nas echoed this, calling troop deployments “a common thing” because the TNI must always stand ready to protect the nation and the integrity of the republic.
Nas laid out the three alert levels to make the point: Siaga 3 is the basic tier with normal activity and movement restrictions; Siaga 2 tightens posture; Siaga 1 is full alert reserved for emergencies such as regional conflict or rapid readiness tests. The current deployment, he said, is Siaga 3 — the floor, not the ceiling.
Civil society reads the same movements differently
The Coalition of Civil Society for Security Sector Reform, in a statement published by YLBHI, pointed to Oct. 28, when TNI soldiers were observed at protest sites around the Hotel Indonesia roundabout and nearby streets. The coalition argues that stationing soldiers among demonstrators blurs the line between national defense and domestic policing and contravenes the TNI law as amended.

“The presence of military personnel in civilian space, especially during public expressions of opinion and criticism, risks creating intimidation and narrowing the space for civil liberties,” the coalition stated, demanding that the TNI immediately withdraw troops from protest security and not use armed force against demonstrators.
The coalition grounded its objection in the post-1998 reform settlement: the constitution separates the TNI’s defense role from the police’s job of keeping public order, and peaceful protest, it argued, “is not a military threat requiring troop deployment.”
Government: nothing to worry about
Coordinating Minister for Law, Human Rights, Immigration and Corrections Yusril Ihza Mahendra, speaking in Banda Aceh on Nov. 4, said Jakarta’s security situation was “ordinary, nothing worrying occurred.” He declined to detail the deployment, saying that falls to the defense minister and the TNI commander, ANTARA reported.
Neither Nas nor the Navy disclosed what scenario the 20,980 personnel are meant to counter, and when asked whether the troops were positioned against upcoming demonstrations, Nas did not respond, detikNews reported. The next dated milestone on record is the fourth phase: 13,140 sailors standing by at their headquarters, ready to deploy whenever the order comes.
