Often overshadowed by larger, more iconic tanks of the Second World War, the LT vz. 35—later reclassified by the Germans as the Pz. Kpfw. 35(t)—was a surprisingly effective and influential machine. Designed by the Škoda company, this Czechoslovak light tank combined mobility, mechanical innovation, and dependable performance to become a key armoured asset during the early Blitzkrieg campaigns in Poland and France. Though it lacked heavy armour and firepower compared to later war machines, its adaptability and reliability in varied terrains earned it respect on the battlefield. This monograph offers a comprehensive look at the LT vz. 35’s development, combat deployment, and technical evolution. From its origins as a symbol of interwar Czechoslovak military ingenuity to its widespread use by German, Slovak, Bulgarian, and Romanian forces, it sheds new light on a vehicle that quietly helped shape early tank warfare. Combining technical detail, operational history, and rarely seen images, Panzer 35(t) is an essential read for anyone interested in armoured warfare, overlooked machines of the Second World War, or the legacy of Central European military engineering.
