Taiwan's Han Kuang exercises this week deploy US-made Abrams tanks for the first time in the drill's history, alongside reserve mobilization and urban resilience testing across the island. The exercise is the largest Han Kuang since the drill's creation, and it runs concurrent with a Taiwan defense ministry tally of 21 Chinese warplanes and 14 warships operating near the island, a presence count the ministry now publishes daily. The Abrams arrived under a 2019 sale approved in President Tsai Ing-wen's first term; their appearance in reserve-mobilization drills, not just live-fire ranges, is the tell. Tanks in a reservist call-up scenario are not a deterrence photo op. They are an inventory check for a mobilization Taipei's Ministry of National Defense now rehearses as a near-term contingency, not a hypothetical one.

Beijing's answer sits in a different weapons class. The DF-17, a hypersonic glide vehicle mated to a ballistic booster, is nearing operational readiness, according to reporting this week, and it renders the Abrams' battlefield utility beside the point. A tank division does not intercept a glide vehicle that separates from its booster mid-flight and maneuvers through the atmosphere. Taipei is drilling for the invasion that follows a landing; Beijing is fielding the weapon that would decide whether a landing force ever needs cover. The mismatch is the story Han Kuang's own footage does not show, and it is the reason the exercise reads less as deterrence than as triage: hardening what a ground force can reach, because the missile force is not Taiwan's to counter.
