A serious, modern book cover design for a non-fiction military strategy title: 'The Decline of the Joint Arms Battle Concept'. The cover should feature a futuristic battlefield with autonomous drones, robotic combat units, and long-range missile systems replacing traditional tank and infantry formations. The background conveys a shift from classic joint-force warfare to digital, remote-controlled combat. The design is minimalist, using dark tones with deep blues and metallic grays, symbolizing technological transformation. The title is bold and clean, suggesting analysis, innovation, and the future of warfare.
