Strategic defence

Strategic defence 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 Strategic defence rather than just read about it. In short: Strategic defence is a type of military planning doctrine and a set defense and/or combat activities used for the purpose of deterring, resisting, and repelling a strategic offensive, conducted as either a territorial or airspace, invasion or attack; or as part of a cyberspace attack in cyberwarfare; or a naval offensive to interrupt shipping lane traffic as a form of economic warfare. Strategic defense is not alway…

Key takeaways

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

Reference excerpt

Strategic defence is a type of military planning doctrine and a set defense and/or combat activities used for the purpose of deterring, resisting, and repelling a strategic offensive, conducted as either a territorial or airspace, invasion or attack; or as part of a cyberspace attack in cyberwarfare; or a naval offensive to interrupt shipping lane traffic as a form of economic warfare. Strategic defense is not always passive in nature. In fact, it often involves military deception, propaganda and psychological warfare, as well as pre-emptive strategies. All forms of military defense are included in the planning, and often civil defense organisations are also included. In military theory, strategic defense thinking seeks to understand and appreciate the theoretical and historical background to any given war or conflict scenario facing the decision-makers at the highest level. Therefore, to fully understand strategic defense activities, analysts need to have a detailed understanding of the relevant geopolitical and socioeconomic challenges and issues that faced the nation state or large organization being studied. Some of the more common issues encountered by strategic defense planners include:

Problems of security and confidence-building in interstate relationships in the strategic neighbourhood National defense policy Arms proliferation and arms control in the immediate strategic region, or within reach of the weapon systems in question Policy advice to the higher levels of the national defense organisation The strategic implications of developments in the nation's geographic region Reviewing security agenda and formulating a new one if necessary Strategic defense is also a predominant peacetime posture of most nation-states in the world at any given time. Although national military intelligence services are always conducting operations to discover offensive threats to security to ensure adequate warning is provided to bring defense forces to a state of combat readiness. In terms of combat scale, a strategic defensive is considered a war that can last from days to generations or a military campaign as a phase of the war, involving a series of operations delimited by time and space and with specific major achievable goal allocated to a defined part of the available armed force. As a campaign, a strategic defence may consist of several battles, some of which may be offensive in nature, or may result in the conduct of withdrawals to new positions, encirclements, or sieges by the defender or the attacker as a means of securing strategic initiative. The strategic goal of a strategic defensive may require a conduct of an offensive operation far removed from the main national territory, such as the case with the 1982 Falklands campaign, which sets logistics apart as the dominant consideration in strategic defensive as a doctrine.

Worked examples

Example 1 — a first encounter with Strategic defence

Start with the simplest possible case. Write down what Strategic defence 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 Strategic defence 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 Strategic defence 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 Strategic defence

In research
Strategic defence 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 Strategic defence 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
Strategic defence is common in secondary-school and first-year university syllabi. It links to neighbouring topics Military strategy, Military theory, so understanding it makes those chapters shorter.
In everyday life
Look for Strategic defence 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 Strategic defence in simple terms?

Strategic defence is a type of military planning doctrine and a set defense and/or combat activities used for the purpose of deterring, resisting, and repelling a strategic offensive, conducted as either a territorial or airspace, invasion or attack; or as part of a cyberspace attack in cyberwarfar…

Why does Strategic defence 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 Strategic defence?

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.
