In this essay, the author explores the dynamic relationship between the traditional military concepts of ‘Decisive Battle’ and ‘Operational Art’. While ‘Decisive Battle’ traditionally embodies the idea of a single, pivotal confrontation that determines the outcome of a conflict, ‘Operational Art’ emphasises a more comprehensive, multifaceted approach to warfare, often involving a sequence of strategic actions. The author also explores the importance of ‘Operational Art’ and highlights how the use of it helps to bring about a swift and decisive victory in war.
