Taiwan's military conducted a joint defense exercise from June 24 to June 28 to simulate enemy launches and territorial incursions [1].

These drills come amid rising cross-strait tensions with China. The exercises focus on improving the Republic of China Armed Forces' ability to respond to sudden aggression through modernized combat strategies.

The military designated the event as an "Immediate Combat Readiness Exercise" [1]. The operation lasted five days [1], beginning on Monday, June 24, 2026 [1]. These activities took place across Taiwan and within its territorial waters [2].

According to official reports, the training focused on testing decentralized targeting, and distributed command and control [2]. By moving away from centralized hubs, the military aims to ensure that operational capabilities remain intact even if primary command centers are compromised during a conflict.

The exercises also emphasized joint operations between different military branches [2]. This coordination is intended to refine the response to simulated enemy incursions, and missile launches [2].

These drills served as a precursor to the annual Han Kuang exercises [2]. While some reports describe the event as a separate preparation phase, others indicate it is an integral part of the broader Han Kuang series [3]. The military used the period to evaluate readiness and the effectiveness of its distributed defense architecture [1].

“The operation lasted five days, beginning on Monday, June 24, 2026.”

The shift toward decentralized targeting and distributed command and control reflects a strategic pivot in Taiwan's defense posture. By reducing reliance on a few centralized command nodes, the military seeks to mitigate the risk of a 'decapitation strike' and increase the resilience of its defense network against high-precision weaponry.
