The author of this breviary ranges from Leonardo da Vinci, the "father of the tank", the "all-round protected combat vehicle", to the "father of the tank weapon", Guderian, to Paul Werner Krapke, the "father of the Leopard". Unterseher presents a "short collection of important passages" from 40 years of analysis of what he wants politicians, military officials and engineers to know about the planning, performance, use and efficiency of armored combat vehicles. Last but not least - and acutely: with the war in Ukraine in mind.
