Strategic depth

Strategic depth 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 depth rather than just read about it. In short: Strategic depth is a term in military literature that broadly refers to the distances between the front lines or battle sectors and the combatants' industrial core areas, capital cities, heartlands, and other key centers of population or military production. Concept The key precepts any military commander must consider when dealing with strategic depth are how vulnerable these assets are to a quick, preemptive attac…

Key takeaways

  • Strategic depth 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 depth to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Strategic depth from memory before moving on to harder problems.

Reference excerpt

Strategic depth is a term in military literature that broadly refers to the distances between the front lines or battle sectors and the combatants' industrial core areas, capital cities, heartlands, and other key centers of population or military production.

Concept The key precepts any military commander must consider when dealing with strategic depth are how vulnerable these assets are to a quick, preemptive attack or to a methodical offensive and whether a country can withdraw into its own territory, absorb an initial thrust, and allow the subsequent offensive to culminate short of its goal and far from its source of power. Commanders must be able to plan for both eventualities and have measures and resources in place on both tactical and strategic levels to counter any stages of a minor or major enemy attack. The measures do not need to be limited to purely military assets since the ability to reinforce civilian infrastructure or make it flexible enough to withstand or evade assault is very useful in times of war. The issue was the tradeoff between space and time as witnessed by Germany’s failure to defeat the Soviet Union in 1942. In the face of a German invasion, the Soviet military retreated from occupied Poland in June 1941 to the outskirts of Moscow in December 1941, which allowed the Soviet Union to move its industrial base to the east of the Ural Mountains. Thus, the industries that had been moved were able to produce the resources that were needed for the Soviet counterattack.

In reference to Pakistan

In Pakistan, the idea of strategic depth was perceived in the 1980s by the National Defence University, Pakistan, Professor General Mirza Aslam Beg (later Chief of Army Staff working under Prime Minister Benazir Bhutto in the 1980s). Since then, the Pakistan military establishment has been repeatedly accused of forming a policy that seeks to control Afghanistan, a policy often referred to by the media as "strategic depth", which is used as the reason for Pakistan's support of certain factions of the Taliban in Afghanistan. In the years 2014–2015, with Pakistan's domestic operation against militants in full swing, Pakistani military leaders said that they adhered to no such policy.

Accusations against the Pakistan military The term "strategic depth" has been used in reference to Pakistan's utilization and contact with Afghanistan following the neighboring country's Soviet intervention, to prevent encirclement from a hostile India and a USSR-supported Afghanistan. Some sources state that the policy to control Afghanistan was formulated by NDU professor, General Mirza Aslam Beg, and an Indian source claims this was continued as an active policy by the Pakistan Armed Forces until the policy was "de jure abolished in 1998 and de facto abolished in 2001", a period when General Pervez Musharraf was the Chairman Joint chiefs. According to Richard Olson, U.S. Ambassador to Pakistan, Pakistan military's doctrine of "strategic depth" is a concept in which Pakistan uses Afghanistan as an instrument of strategic security in ongoing tensions with India by attempting to control Afghanistan as a pawn for its own political purposes. It has been speculated that the Pakistan's military "strategic depth" policy is either military or non-military in nature. The military version would state that the Pakistan military wishes to use Afghan territory as a "strategic rallying point" where they can, in the event of a successful Indian attack, retreat to and re-group for a counter-attack. The non-military version would be based on the idea that Pakistan can improve relations with other Islamic countries and former Soviet states such as Uzbekistan and Kazakhstan, developing improved economic and cultural ties with them and thus making them into strong allies against India.

View of the Pakistan military The former Chief of Army staff General Ashfaq Kayani, and previously the director-general of the ISI, has repeatedly stated to the media that the Pakistan armed force's "strategic depth" policy with regards to Afghanistan is not to "control" Afghanistan but to ensure a "peaceful, friendly and stable" relationship with Afghanistan. This policy therefore aims to ensure that Pakistan will not be threatened with long-term security problems on its Western border with Afghanistan. According to Kayani, a 'talibanised' Afghanistan is not in Pakistan's interests. According to Ejaz Haider, a Pakistani military journalist, there is a confusion in the media regarding the policy on using Afghan territory to as a fallback area for Pakistan military assets. Haider blames General Mirza Aslam Beg for proposing this when he was the chief of army staff of the Pakistan Army under Prime Minister Benazir Bhutto, stating that this concept "was unpopular even when he was the chief and it has never been entertained by serious military planners. No one thinks of placing military and other assets in Afghanistan and thus acquiring strategic depth." Haider states that such a concept has always been impossible "for a host of reasons" and strategic depth is better used to describe achieving security through improving relationships with the governments of neighbouring countries such as Afghanistan and India. Lieutenant-General Asad Durrani of ISI, has rubbished claims in the media regarding Pakistan intending to use Afghan territory as "strategic depth". He also denies accusations that the Pakistan military has tried to "install a friendly government in Kabul" to "secure this depth". He gives the Soviet Union as an example, stating that "after the Saur Revolution, the Soviets executed and installed a president every three months in pursuit of that objective" and these policies later resulted in the defeat of the Soviets in Afghanistan. He argues that the notion of Pakistan using Afghan territory for its own purposes is a "distortion of a concept or of history" and is being used to vilify Pakistan.

In China During the Cold War, Mao Zedong's Third Front campaign to increase the strategic depth of the People's Republic of China (PRC) by locating critical infrastructure and national defense facilities in the interior of the country and away from areas where they would be vulnerable to Soviet invasion or U.S. air attacks. PRC military analysts view control over Taiwan as allowing the country to break out of the first island chain and increase its strategic depth.

Worked examples

Example 1 — a first encounter with Strategic depth

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

In research
Strategic depth 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 depth 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 depth is common in secondary-school and first-year university syllabi. It links to neighbouring topics History of the foreign relations of Pakistan, Military doctrines of Pakistan, Military geography, so understanding it makes those chapters shorter.
In everyday life
Look for Strategic depth 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.
