TAIPEI: Taiwan began major military drills on Wednesday (Aug 5) to test commanders' ability to fight on the fly when enemy movements defy expectations, while temporarily limiting internet access for the first time, senior Taiwan officials said. The 10-day annual Han Kuang exercise began early in the morning after an underground command centre in Taipei issued the drill order, triggering combat-readiness moves that will include fighter jet dispersals and emergency naval deployments, two senior Taiwan officials briefed on the matter told Reuters. The move, one of the officials said, is to "ensure commanders and subordinates are in sync on operational intent". The drill will also focus on a key wartime concern: that China, which claims Taiwan as its own despite the island's objections, would try to paralyse command centres, ports, logistics and defence industry sites early in an attack. China has never renounced the use of force to bring Taiwan under its control.
