Runner (messenger)

Runner (messenger) 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 Runner (messenger) rather than just read about it. In short: In military, a runner was a foot soldier responsible for carrying messages between units during war. Runners were very important to military communications, before telecommunications became commonplace.

Key takeaways

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

Reference excerpt

In military, a runner was a foot soldier responsible for carrying messages between units during war. Runners were very important to military communications, before telecommunications became commonplace. Non-military runners were also used, e.g., by World War II resistance fighters. In Ancient Greece, Hemerodromoi (day-runners), Hemeroscopoi (day-watchers) and Dromokerykes (runner heralds) were employed to carry important news and perform surveillance. They swiftly relayed the information to the appropriate authorities, ensuring timely responses to emerging situations. When equipped with a bicycle or other transport, the runner became a despatch rider.

20th century Even though field telephones were widely used for the first time during World War I (1914–18), they relied on copper wire lines, which were often damaged or unreliable, or simply unavailable as troops advanced. Radio technology existed, but was generally regarded as too insecure for frontline use. Most armies still made extensive use of runners throughout the war. Runners were lightly equipped with only a sidearm, canteen and a light pack. On battlefields dominated by automatic weapons and trench warfare, as well as the first widespread use of artillery and air attacks, runners faced one of the most dangerous jobs as they had to leave the relative safety of a shelter, and carry messages to other positions. For the same reasons, officers could not be sure that their message had been delivered until a runner returned to their unit. Runners were frequently decorated for bravery. Adolf Hitler, who was a runner in the Bavarian Army during World War I, was wounded twice and received both the Iron Cross first class and second class during the war.

Worked examples

Example 1 — a first encounter with Runner (messenger)

Start with the simplest possible case. Write down what Runner (messenger) 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 Runner (messenger) 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 Runner (messenger) 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 Runner (messenger)

In research
Runner (messenger) 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 Runner (messenger) 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
Runner (messenger) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Combat occupations, Military communications, Postal history, so understanding it makes those chapters shorter.
In everyday life
Look for Runner (messenger) 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.
