Military theory

Military theory is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Military theory rather than just read about it. In short: Military theory is the study of the theories which define, inform, guide and explain war and warfare. Military theory analyses both normative behavioral phenomena and explanatory causal aspects to better understand war and how it is fought.

Key takeaways

  • Military theory belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Military theory to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Military theory from memory before moving on to harder problems.

Reference excerpt

Military theory is the study of the theories which define, inform, guide and explain war and warfare. Military theory analyses both normative behavioral phenomena and explanatory causal aspects to better understand war and how it is fought. It examines war and trends in warfare beyond simply describing events in military history. While military theories may employ the scientific method, theory differs from military science. Theory aims to explain the causes for military victory and produce guidance on how war should be waged and won, 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 theory is multi-disciplinary drawing on social science and humanities academic fields through the disciplines of political science, strategic studies, military studies and history. It examines the nature of war, and the conclusions of wars. 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 and Sun Tzu. While military theory can inform military doctrine or help explain military 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.

Use of military theory 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.' Military theory informs the political, strategic, operational and tactical levels of war. 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. Military theories can be divided into several categories, such as operational theory and tactical theory. They may also be categorised by environment or domain, such as space power or astronautics.

Worked examples

Example 1 — a first encounter with Military theory

Start with the simplest possible case. Write down what Military theory claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Military theory before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Military theory ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Military theory

In research
Military theory appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Military theory in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Military theory is common in secondary-school and first-year university syllabi. It links to neighbouring topics Military doctrines, Military theory, so understanding it makes those chapters shorter.
In everyday life
Look for Military theory outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Military theory in simple terms?

Military theory is the study of the theories which define, inform, guide and explain war and warfare. Military theory analyses both normative behavioral phenomena and explanatory causal aspects to better understand war and how it is fought.

Why does Military theory matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Military theory?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.

What does this page cover?

It gives you a compact reference excerpt plus original lgStudy explanations, examples, applications and study material on Military theory.
