Military theory is the study of thetheories which define, inform, guide and explainwar andwarfare. Military theory analyses bothnormative behavioral phenomena andexplanatory causal aspects to better understand war and how it is fought.[1] It examines war and trends in warfare beyond simply describing events in military history.[2] While military theories may employ thescientific method, theory differs frommilitary science. Theory aims to explain the causes for military victory and produce guidance on how war should be waged and won,[3] rather than developing universal, immutable laws which can bound the physical act of warfare or codifying empirical data, such as weapon effects, platform operating ranges, consumption rates and target information, to aid military planning.
Military philosophy likewise studies questions such as the reasons to go to war,jus ad bellum, and just ways to fight wars,jus in bello. Two of the earliest military philosophers date from antiquity;Thucydides andSun Tzu.[5][6] While military theory can informmilitary doctrine or help explainmilitary history, it differs from them as it contemplates abstract concepts, themes, principles and ideas to formulate solutions to actual and potential problems concerning war and warfare.[7]
Prussian military theorist Carl von Clausewitz wrote,
'The primary purpose of any theory is to clarify concepts and ideas that have become, as it were, confused and entangled. Not until terms and concepts have been defined can one hope to make any progress in examining the questions clearly and simply and expect the reader to share one's views.'[8]
Military theory informs the political, strategic, operational and tactical levels of war.[9] It does so by contributing to knowledge on the subjects of war and warfare. This aids in understanding why and when force is used and what forms the use of force may take. It also aids in identifying and explaining practical outcomes to help determine how force may be applied.[10] Military theories can be divided into several categories, such asoperational theory andtactical theory.[11][12][13] They may also be categorised by environment or domain, such asspace power or astronautics.[14]
