The situation
Taiwan began the live-force phase of its annual Han Kuang exercise on August 5 at multiple locations across the island. The 10-day programme tests 24-hour defensive operations, responses to coercive “gray-zone” activity, more decentralised communications practices and the mobilisation of more than 5,000 reservists across two brigades.
Associated urban-resilience measures are scheduled to begin on August 7 in Kaohsiung, Taichung and Taipei, followed by air-defence phases from August 10 to 13. Taiwan’s exercise planning requires people and organisations in designated areas to comply with relevant civil-defence control measures. The drill is a recurring preparedness exercise and does not establish that an attack is imminent.
Why it matters
The exercise tests whether Taiwan can maintain command, mobilise reserves and coordinate civilian support during sustained coercion or conflict, rather than relying solely on initial military responses. Its larger reservist component and urban-resilience phases put greater emphasis on the continuity of national defence and public services under disruption.
For regional security, the exercise signals continued Taiwanese investment in deterrence and resilience as Chinese military pressure remains the strategic backdrop. No verified blockade, exclusion zone, casualty event or immediate disruption to shipping, trade or humanitarian access is established by the available evidence.
What changed
Taiwan moved from planning to execution on August 5, beginning the 2026 Han Kuang live-force exercise with its largest reported reservist participation to date.
Impacts
Military & Security
Taiwan is testing sustained defence, reserve activation and decentralised command against the backdrop of continuing Chinese military pressure. The exercise strengthens readiness assessment but is not evidence of an imminent conflict.
Diplomacy
The exercise reinforces Taiwan’s public emphasis on deterrence and societal resilience in cross-strait security policy, while no new bilateral diplomatic initiative or crisis measure is evidenced.
Trade & Supply Chains
No blockade, exclusion zone or verified disruption to shipping and trade has been established; the main relevance is the longer-term exposure of regional supply routes to cross-strait security risk.
Full edition assessment · Military & Security
Security pressure is elevated and volatile across three direct drivers: Ukraine reported that no incoming missiles were intercepted during the 5 August strike on Kyiv and the surrounding region; maritime risks remain unresolved at the Strait of Hormuz despite a reported draft transit plan; and Taiwan has begun a large readiness exercise focused on sustained defence, reserve mobilisation and decentralised command. China’s new reviews of U.S.-bound drone and dual-use exports add strategic friction, but the available evidence does not verify a specific military procurement effect.
The sharpest immediate vulnerability is Ukraine’s air defence around Kyiv. Taiwan’s exercise improves testing of resilience rather than evidencing imminent conflict, while Hormuz risk remains geographically concentrated but globally relevant through maritime access and energy flows.
Low confidence · Volatile · Volatile
Air-defence shortfall raises Kyiv-region exposure
Ukraine linked the absence of reported missile interceptions during the 5 August barrage to depleted Patriot interceptor stocks, demonstrating a current gap against ballistic-missile attack.
Civilian areas and logistics-related facilities around Kyiv are more exposed to repeat long-range strikes while interceptor availability remains constrained.
Signal to watchVerified restoration of ballistic-missile interceptions in subsequent attacks would show whether the reported defensive gap is narrowing.
Readiness measures coexist with unresolved regional coercion risk
Taiwan’s exercise is testing reserve mobilisation, sustained operations and decentralised communications, while the Hormuz negotiations have yet to produce a verified maritime-security regime.
The immediate operational risks are concentrated in the Taiwan Strait and the Gulf rather than evidence of a single coordinated escalation, but both theatres require continued monitoring of access, command resilience and civil-military continuity.
Signal to watchVerified coercive activity affecting Taiwan’s exercise or renewed attacks on commercial vessels near Hormuz would indicate a deterioration in operational security conditions.
What to watch
- Do the August 7 urban-resilience phases proceed in Kaohsiung, Taichung and Taipei under the planned civil-defence control measures?
- Does Taiwan complete the exercise with the planned mobilisation of more than 5,000 reservists across two brigades and sustained 24-hour defence testing?
Taiwan begins urban-resilience phases linked to Han Kuang
Scheduled:
The planned civil-defence phases will test whether military readiness measures can be integrated with urban response and public compliance arrangements.
Verified execution of the scheduled drills in Kaohsiung, Taichung and Taipei.

Useful context
Han Kuang exercise
Taiwan’s annual military readiness exercise, combining force training with wider defence-mobilisation activity.
The 2026 exercise is testing sustained defence, reserve activation and civil resilience.
Gray-zone activity
Coercive activity intended to advance strategic objectives without crossing into open armed conflict.
Taiwan is using the exercise to test responses to this type of pressure.
