Nobody talks about this one. Masamune Shirow takes the absurd premise of tank cops vs. AI tanks and actually makes it work as a tense siege that respects both the hardware and the human problem underneath it. The OVA moves like live action, no padding, no explaining itself twice, and trusts you to keep up with the tactical choreography. It's Shirow doing what he does best: taking military sci-fi seriously enough that the ridiculous parts become inevitable. Watch it if you want mecha action that treats its own scenario like a real problem, not a setup for jokes.
The Dominion Tank Police returns to New Port City for a high-stakes operation. When terrorists seize control of the NT Building and deploy AI-controlled tanks, the police force faces an enemy unlike anything they've encountered before. Leona and Al must navigate a crisis where conventional tactics fail against machines that think faster than humans can react. This OVA strips away the comedic chaos of earlier adventures to focus on pure tactical tension. The threat is immediate, the stakes are concrete, and there's no room for Leona's usual collateral damage. Instead, precision and strategy become the weapons. The AI tanks represent a new frontier in urban warfare, forcing the Tank Police to question whether they're equipped for a future where their opponents don't need to be human. For viewers who loved the franchise's blend of mecha action and cop procedural elements, this entry tightens the formula into something leaner and more urgent. It's about professionals pushed to their limits against technology that threatens to make them obsolete.
