Garuda Shield started in 2006 as a modest army-to-army exchange between the United States and Indonesia. Its expansion into Super Garuda Shield, a combined joint-service exercise open to more than a dozen partners, tracks the shift in how the Indo-Pacific is being organised militarily - away from a hub-and-spoke set of separate United States alliances and towards networked exercises in which partners train with each other and not only with Washington. The 2026 edition covers expert exchanges and professional workshops, a command-and-control exercise, maritime training with naval and coast guard components, and a combined field training exercise. Indonesia's terrain shapes the content: dense tropical jungle for infiltration and close-quarters training, and an archipelagic geography that makes amphibious operations and disaster response the natural focus. The Humanitarian Assistance and Disaster Relief component is not decorative - Indonesia sits on the Pacific Ring of Fire and faces recurring earthquakes, tsunamis and volcanic eruptions, so HADR is a live operational requirement rather than a training scenario.

Indonesia is the largest state in Southeast Asia and the anchor of ASEAN, and its foreign policy has rested since 1948 on the bebas-aktif or independent and active doctrine - non-alignment in substance, engagement in practice. Hosting the largest United States-partnered exercise in the region while simultaneously deepening economic and defence contacts with China is the clearest current expression of that doctrine. The geography explains the stakes: the Malacca, Sunda and Lombok Straits are Indonesian or Indonesia-adjacent chokepoints through which a very large share of world trade and energy passes, and the Malacca Strait in particular carries the bulk of the oil moving to East Asia. For India the exercise matters at one remove. India is not a participant, but it holds its own bilateral exercises with Indonesia - the Samudra Shakti naval exercise and the long-running IND-INDO CORPAT coordinated patrol along the international maritime boundary near the Andaman and Nicobar Islands - and India's Act East policy treats Indonesia as a principal maritime partner.
