Principles of sustainment

Principles of sustainment 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 Principles of sustainment rather than just read about it. In short: Principles of sustainment or principles of logistics are a set of military principles from the United States Army doctrine. They are essential to maintaining combat power, enabling strategic and operational reach, and providing US Army forces with endurance.

Key takeaways

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

Reference excerpt

Principles of sustainment or principles of logistics are a set of military principles from the United States Army doctrine. They are essential to maintaining combat power, enabling strategic and operational reach, and providing US Army forces with endurance. While these principles are independent, they are also interrelated. U.S. Army Doctrine Publication 4-0, published 31 July 2012 addresses sustainment principles.

Integration is combining all of the elements of sustainment (tasks, functions, systems, processes, organizations) to operations assuring unity of command and effort. Army forces integrate sustainment with joint forces and multinational operations to maximize the complementary and reinforcing effects from each Service and national resources. Anticipation is the ability to foresee operational requirements and initiate actions that satisfy a response without waiting for an operations order or fragmentary order. Sustainment commanders and staffs visualize future operations, identify required support and start the process of acquiring the sustainment that best supports the operation. Responsiveness is the ability to react to changing requirements and respond to meet the needs to maintain support. Through responsive sustainment, commanders maintain operational focus and pressure, set the tempo of friendly operations to prevent exhaustion, replace ineffective units, and extend operational reach. Simplicity relates to processes and procedures to minimize the complexity of sustainment. Clarity of tasks, standardized and interoperable procedures, and clearly defined command relationships contribute to simplicity. Economy is providing sustainment resources in an efficient manner to enable a commander to employ all assets to achieve the greatest effect possible. It is achieved through efficient management and discipline, prioritizing and allocating resources, and capitalizing on joint interdependencies. It can also be achieved by contracting for support or using host nation resources to reduce or eliminate the use of military resources. Survivability is all aspects of protecting personnel, weapons, and supplies while simultaneously deceiving the enemy (JP 3-34). Survivability consists of a quality or capability of military forces which permits then to avoid or withstand hostile actions or environmental conditions while retaining the ability to fulfill their primary mission. In mitigating risks and minimizing disruptions to sustainment, commanders often must rely on the use of redundant sustainment capabilities and alternative support plans. Continuity is the uninterrupted provision of sustainment across all levels of war. It is achieved through a system of integrated and focused networks linking sustainment across the levels of war, other Service support capabilities, and to operations. It assures confidence in sustainment allowing commanders’ freedom of action, operational reach and prolonged endurance. Improvisation is the ability to adapt sustainment operations to unexpected situations or circumstances affecting a mission. It includes creating, inventing, arranging, or fabricating what is needed from what is available. The sustainment commander must apply operational art to visualize complex operations and understand what is possible at the tactical level. These skills enable commanders to improvise operational and tactical actions when enemy actions unexpected events disrupt sustainment operations.

Worked examples

Example 1 — a first encounter with Principles of sustainment

Start with the simplest possible case. Write down what Principles of sustainment 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 Principles of sustainment 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 Principles of sustainment 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 Principles of sustainment

In research
Principles of sustainment 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 Principles of sustainment 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
Principles of sustainment is common in secondary-school and first-year university syllabi. It links to neighbouring topics Military doctrines, United States Army doctrine, so understanding it makes those chapters shorter.
In everyday life
Look for Principles of sustainment 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.
