According to Taiwan's United Daily News and others, this Han Kuang exercise for the first time conducted blocking and barrier-laying drills sealing a stretch of the Tamkang Bridge. Engineer units set three obstacle lines.

Bridges and major thoroughfares are chokepoints for moving troops and supplies in a crisis—and, conversely, key points for slowing an enemy advance. Sealing routes and laying obstacles are seen as basic engineering tasks to secure defensive depth.

The drill used a scenario based on a real bridge and urban infrastructure, with a strong element of applying defensive concepts to actual terrain, aimed at testing blocking capability in urban and bridge settings.

Authorities stressed the drill was defensive in nature. Advance notice and control procedures were also carried out to minimize the impact on residents' movement and safety.

Hwagyo Sibo handles cross-strait matters on a principle of factual reporting rather than any camp's stance. For Chinese residents and visitors in Taiwan, traffic controls and safety notices tied to drills are information they need in daily life.
