Also on Monday, August 10, at 2:30 p.m. local time, Taiwan deliberately slowed mobile internet for the first time as part of a war game. Mobile data across seven central counties—Miaoli County, Taichung, Nantou County, Changhua County, Yunlin County, Chiayi County, and Chiayi City—was throttled to roughly 0.5–1 Mbps (about 1% of normal 5G speeds) for 30 minutes . Fixed-line services, landlines, emergency numbers, ATMs, and traffic signals were unaffected, and the Taiwan Stock Exchange received an exemption to avoid market disruption .
The drill simulated communications breakdowns from a Chinese attack or natural disaster, testing how citizens and businesses would function with severely limited bandwidth . A second throttle was scheduled for Thursday, August 13, covering seven jurisdictions in northern Taiwan as part of the broader urban resilience exercise .
On Sunday, August 9 (Day 5 of the live-fire segment), the Army’s Chemical Group in Hualien County (eastern Taiwan) conducted a full-scale NBC decontamination drill . The scenario was designed around a chemical weapons attack on armored vehicles and personnel by the Hualien Armored Vehicle Unit of the Army’s Second Combat Zone . Notably, the drill assumed the enemy was already inside Taiwan’s defenses—Chinese intelligence operatives had penetrated multiple military positions and released toxic gases specifically to prevent armored units from moving north to reinforce Taiwan’s more exposed front lines . Troops practiced evacuating contaminated personnel and vehicles to recovery zones, establishing temporary decontamination stations, and restoring combat capability .
On the first night of the exercises (Wednesday, August 5), President Lai Ching-te participated in a “Wan Chun” (anti-decapitation) contingency exercise. Wearing body armor and a helmet, he was rushed in a Clouded Leopard armored personnel carrier to a secure, underground command center (the National Political and Military Operations Command Center) to simulate how the government would continue functioning if a PLA decapitation strike targeted Taiwan’s leadership . On Saturday, August 8, Lai also oversaw coastal strike drills near Kaohsiung, boarding a fast-attack missile boat and observing low-flying attack drones simulating the repelling of a Chinese amphibious assault .
Other notable components across the 10-day exercise included:
These exercises took place amid steadily escalating Chinese military pressure against Taiwan. Beijing rejects Taiwan’s self-governance and claims the island as its own territory, a position the AP noted in its coverage of the drills . The heightened urgency of the 2026 Han Kuang exercises is widely understood by analysts to be connected to China’s reported 2027 military readiness goals—a publicly discussed benchmark by which the PLA is expected to achieve the capability to conduct a large-scale invasion of Taiwan. While direct official statements about a “2027 deadline” are not found in the specific articles gathered here, major news outlets consistently report this timeline as the key driver behind Taiwan’s accelerated defense posture, including the unprecedented integration of civilian resilience drills into the military exercise for the first time this year .
