The panel names Germany immediately despite the familiar logistical weaknesses of Italy and Japan. Those two powers at least understood their likely wars and placed greater value on standardization and simplification. Germany repeatedly treated minor mechanical changes as new marks requiring separate accounting and supply chains. The result was a self-imposed burden of parts, records, and maintenance complexity.
