This third iteration of the exercise focuses on joint counter-terrorism rescue operations in mountainous regions, including helicopter rappelling and manned-unmanned system coordination, signifying deepening practical exchanges.

• New 4-Nation Defense Pact (Badr MOU): Indonesia signed the "Badr" Memorandum of Understanding in Doha on October 21, 2026 (reported October 22-27), with Turkey, Qatar, and Pakistan. This pact outlines a framework for defense cooperation and integration across joint research and development, training exchanges, and industrial capability building, aiming to expand joint arms production and technology transfers.

• Continued Military Modernization and Acquisitions: Indonesia is rapidly modernizing its military, with significant acquisitions from Europe and Turkey. Recent developments include the commissioning of the first six Dassault Rafale F4 fighter jets into Air Squadron 12 in May 2026, and contracts for 48 TAI KAAN stealth fighters from Turkish Aerospace Industries. The former Italian aircraft carrier ITS Giuseppe Garibaldi was commissioned as KRI Sriwijaya in September 2026, and Indonesia has taken delivery of Italian Offshore Patrol Vessels (PPA) and contracted for Turkish Istanbul-class frigates.

• Diplomatic Push for Defense Industry Growth: Newly appointed Foreign Minister Arrmanatha Nasir stated on October 12, 2026, that Indonesia would use diplomatic efforts to grow its defense industry, emphasizing technology transfers and domestic production. This aligns with Indonesia's "free and active" foreign policy, seeking diversified partnerships without joining military blocs.

• Indonesia-Singapore Bilateral Engagements: Indonesian Foreign Minister Arrmanatha Nasir met with Singaporean Foreign Minister Dr. Vivian Balakrishnan in Jakarta on October 27, 2026, to discuss strengthening strategic cooperation. President Prabowo Subianto also met with Minister Balakrishnan on October 28, 2026. A key outcome was the agreement to establish a joint task force to investigate companies responsible for forest fires and transboundary haze, facilitating information sharing and financial intelligence exchanges.

• President Prabowo's "Survival Mode" Doctrine: In a cabinet meeting on October 21, 2026, President Prabowo Subianto declared Indonesia to be in "survival mode" amidst global geopolitical challenges, emphasizing the importance of national unity and protecting national wealth and natural resources. He asserted that Indonesia would not be intimidated by external pressures, including those related to financial markets.

• Ongoing Protests and Security Deployments: On October 28, 2026, Indonesia deployed hundreds of security personnel across Jakarta ahead of planned student demonstrations against President Prabowo Subianto's policies and the government's handling of widespread forest fires. These protests, organized under the hashtag #IndonesiaAware, called for stronger action on the environmental crisis. Additionally, there were reports of intelligence officers visiting an activist in Merauke Regency, Papua, on October 7, 2026, raising concerns about civic space.

• Maritime Security Focus: The Maritime Security Forum (MSF) 2026 was held in Cirebon, Indonesia, on October 29-30, 2026, focusing on "Navigating Uncertainty: Building Resilient Maritime Security in a Changing Risk Landscape." This forum brought together industry leaders, government, and defense representatives to address evolving threats, risk management, and operational resilience in the maritime sector.

Geopolitical Impact and Regional Dynamics

Indonesia's security developments during this period underscore its strategic autonomy and growing influence in regional and global affairs. The robust military modernization program, characterized by diverse acquisitions from France, Turkey, and Italy, reflects a pragmatic approach to defense that avoids over-reliance on any single power. This diversification, coupled with a stated "free and active" foreign policy, positions Indonesia as a non-aligned yet capable actor in the Indo-Pacific. The commissioning of the KRI Sriwijaya aircraft carrier, while enhancing naval capabilities, also signals Indonesia's ambition for greater maritime presence and potential power projection, which could be viewed with varying degrees of apprehension or reassurance by regional neighbors.

The engagement in joint military exercises with both India ("Garuda Shakti 2026") and China ("Sharp Knife 2026") highlights Indonesia's balancing act between major powers. These exercises, focusing on special forces operations and counter-terrorism, demonstrate a commitment to practical security cooperation with diverse partners, rather than exclusive alliances. The "Badr MOU" with Turkey, Qatar, and Pakistan further diversifies Indonesia's defense partnerships, potentially offering new avenues for technology transfer and defense industry development, while navigating the complex geopolitics of the Middle East and South Asia. This multilateral engagement could enhance Indonesia's defense industrial base and reduce dependence on traditional suppliers, but also requires careful diplomatic management to avoid misinterpretations of its non-alignment stance.

Regionally, the renewed focus on cooperation with Singapore, particularly on transboundary haze and forest fires, demonstrates a commitment to addressing shared environmental and security challenges. The establishment of a joint task force for accountability in forest fires is a significant step towards practical, cross-border problem-solving. Indonesia's continued efforts in counter-terrorism, including the evolution of the ASEAN Our Eyes Initiative and collaboration with Australia, contribute to regional stability by strengthening intelligence sharing and operational capabilities against non-traditional threats. President Prabowo's emphasis on national unity and protecting national interests in a "power politics" environment signals a firm stance on sovereignty and resource control, which could resonate with other developing nations but also potentially lead to friction with major powers over economic or strategic interests.

Military and Defense Analysis

Indonesia's military is undergoing a significant modernization program under President Prabowo Subianto, marked by a substantial increase in defense spending. The defense budget for 2026 was budgeted at 337.4 trillion rupiah (approximately $20.5 billion), a notable increase from previous years, demonstrating a clear commitment to strengthening national defense capabilities. This spending is allocated not only for procurement but also for maintenance, infrastructure, domestic defense industry development, and human resource quality improvement.

The force posture is being enhanced through the acquisition of advanced major weapons systems. The Indonesian Air Force is integrating 42 Dassault Rafale F4 fighter jets, with the first six already commissioned, and has contracted for 48 fifth-generation TAI KAAN stealth fighters. The Navy has significantly boosted its capabilities with the commissioning of the KRI Sriwijaya (a former Italian aircraft carrier), the delivery of Italian Offshore Patrol Vessels (PPA), and contracts for Turkish Istanbul-class frigates. Submarine capabilities are also being expanded with two Scorpene submarines under construction domestically with French technology transfer. The Army has deployed Turkish-built Roketsan KHAN/Bora short-range ballistic missile systems, providing a 300-kilometer strike range. These acquisitions indicate a move towards a more technologically advanced and diversified military force.

A key aspect of Indonesia's defense strategy is the development of its domestic defense industry and the pursuit of technology transfers. Deals for KAAN fighters and Rafale warplanes include provisions for local-based industry and technology transfers with state-owned planemaker Dirgantara Indonesia (PTDI). State-owned arms maker Pindad also plans to build a Beijing-backed ammunition factory. This focus on indigenous production aims to reduce reliance on foreign suppliers and build strategic autonomy, although integrating such a diverse array of foreign systems into a coherent fighting force presents a significant challenge.

Outlook and Forecast

Short-term trends (1-3 months):
In the immediate future, Indonesia is likely to continue its active diplomatic and military engagements. The ongoing "Garuda Shakti 2026" exercise with India and "Sharp Knife 2026" with China will conclude in early November, providing insights into enhanced interoperability and counter-terrorism tactics. The newly formed joint task force with Singapore on forest fires is expected to begin operationalizing its information sharing and enforcement mechanisms, potentially leading to initial investigations and actions against responsible companies. Domestically, the government will remain vigilant regarding student protests, particularly those related to environmental issues and government policies, with security forces likely maintaining a visible presence in urban centers like Jakarta. Cybersecurity will remain a critical concern, with BSSN continuing to monitor and respond to high volumes of cyber threats, while initial steps towards post-quantum cryptography migration may be announced.

Critical flashpoints and risk areas:
* Cyber Warfare and Data Breaches: The persistent and high volume of cyber threats, including state-sponsored espionage and data exposure, poses a critical risk to Indonesia's government, critical infrastructure, and private sector. Unverified claims of data breaches in maritime logistics and financial sectors highlight vulnerabilities that could lead to significant economic disruption and loss of public trust.
* Internal Unrest and Human Rights Concerns: Ongoing political protests, particularly those related to environmental issues and government accountability, could escalate, leading to further security deployments and potential clashes. Reports of intelligence activities targeting activists, especially in regions like Papua, raise concerns about civic space and could fuel further dissent.
* Maritime Security in Disputed Waters: While not explicitly highlighted with incidents in this reporting period, Indonesia's extensive maritime domain, including areas bordering the South China Sea, remains a perpetual flashpoint for potential encounters with foreign vessels or illegal activities. The focus on maritime economy and security at forums like MSF 2026 underscores the ongoing importance of this domain.

Indicators to monitor:
* Cybersecurity Incident Reports: Track the frequency, sophistication, and impact of reported cyberattacks and data breaches, particularly those affecting critical infrastructure and government agencies.
* Protest Activity and Government Response: Monitor the scale and nature of public demonstrations, government responses, and any legislative or policy changes addressing the underlying grievances, such as forest fire management.
* Defense Acquisition Progress and Integration: Observe the delivery schedules of major defense platforms (Rafale, KAAN, KRI Sriwijaya) and any public statements or exercises demonstrating their integration into a coherent force.
* Diplomatic Engagements and Defense Pacts: Watch for further developments or concrete projects stemming from the Badr MOU and other bilateral defense cooperation agreements, assessing their impact on Indonesia's strategic autonomy.
* Economic Stability: Given President Prabowo's "survival mode" rhetoric and concerns about financial markets, monitor economic indicators and government policies aimed at protecting national wealth and resources.

Strategic recommendations:
1. Strengthen Cyber Resilience: Prioritize investment in advanced cybersecurity defenses, threat intelligence sharing, and human capital development. Expedite the implementation of post-quantum cryptography and robust data protection frameworks across all critical sectors.
2. Proactive Public Engagement: Address public grievances transparently, particularly concerning environmental issues like forest fires. Foster open dialogue and ensure respect for civic space to mitigate the risk of escalating protests and maintain social cohesion.
3. Enhance Maritime Domain Awareness: Continue investing in maritime surveillance, patrol capabilities, and regional cooperation mechanisms to secure Indonesia's vast maritime territory and protect its economic interests.
4. Strategic Integration of Defense Assets: Focus on the seamless integration and interoperability of newly acquired diverse defense platforms to ensure they function as a cohesive and effective fighting force, rather than disparate assets.
5. Balanced Diplomatic Strategy: Maintain a "free and active" foreign policy by diversifying defense partnerships while carefully managing perceptions to avoid being drawn into major power rivalries. Leverage defense diplomacy to secure technology transfers and boost the domestic defense industry.
