Taiwan's military is tightening its guard on the northern coast, a routine but telling sign of how seriously the island treats the threat from China.

• Defense Minister Wellington Koo visited army and navy units around Keelung ahead of the Mid-Autumn Festival.
• He checked how troops patrol the surrounding waters and protect key infrastructure like ports and power sites.
• Keelung sits at a strategic spot on the north coast, guarding the approach to Taipei.
• Koo wants the lessons from the Han Kuang war games turned into real improvements in combat readiness.
• Troops got bonuses and holiday greetings, with officers told to look after soldiers' living conditions and morale.

Outlook: Expect Taiwan to keep drilling and hardening its northern defenses, with Han Kuang findings shaping the next round of readiness work.
