In the autumn of 2022, the Ukrainian army accomplished a military masterpiece. The study "Kharkiv Offensive Operation 2022" by the Central Research Institute of the Armed Forces of Ukraine analyzes this turning point in the war. The book documents how the defenders succeeded in seizing the initiative and, in a counteroffensive, liberating an area of almost 11,500 km² andnearly 500 settlements from Russian occupation. The focus is on Ukrainian tactics: a thrust in which fast shock troops, combined with mechanized forces and long-range artillery, broke through the Russian defenses. Instead of wearing themselves out in towns, they bypassed positions, pushed deep into the rear, and cut off logistics hubs like Balakliia and Izium. This led to a panic-stricken retreat by the invaders, who left behind massive amounts of equipment, and forced Putin to declare a partial mobilization. With reports from actors such as Colonel General Syrskyi, the work provides insights into the planning and execution of the operation. It sheds light on challenges such as ammunition shortages, the role of Western weapons assistance, brilliant disinformation, and the motivation of the troops. An essential read to understand the strategies that brought Ukraine this victory and decisively strengthened the international coalition to support the country.
