The science of strategy is a theoretical system about strategy and a discipline that studies the overall guiding laws for the use and construction of military forces. Its main task is to reveal the essence, characteristics, and basic principles of strategy, to study the guiding laws of military conflict and army building as a whole, and to provide systematic and scientific theoretical guidance for the formulation and implementation of strategy. Strategy has developed with the development of military practice, especially strategic practice, and is closely related to the development of disciplines in various fields such as politics, economy, diplomacy, science and technology, culture, and geography. Different countries and armies have different strategic theoretical systems under different historical conditions.
