Military

• 1. Introduction

  ›

  In the year 1274 BC, the Battle of Kadesh unfolded under the reign of Ramses II, and its scenes were carved into bas-relief monuments so that the power of military leaders would outlast the men themselves. A military is a heavily armed, highly organized force, intended above all for warfare. It is typically authorized and maintained by a sovereign state, its members marked apart by a distinct uniform. But the word covers far more than soldiers in a line. The profession of soldiering is older than recorded history. The questions that follow ask what a military actually is, how it turns ordinary people into combatants, how it thinks before it fights, and how the tools of war have reshaped war itself. The first answer hides in plain sight, inside a single English word first written down in 1582.

• 2. A Word And Its Burden

  ›

  Spelled militarie, the word entered English in 1582, carried from the Latin militaris, by way of French, with an uncertain root. One suggestion traces it to a sense of going in a body or a mass. As a noun phrase, "the military" usually means a country's armed forces, and sometimes the senior officers who command them. It points to the physical reality of those forces, their personnel, their equipment, the ground they occupy. The adjective once referred only to soldiers and soldiering. Then it widened to cover land forces in general, a shift visible in the names of the Royal Military Academy of 1741 and the United States Military Academy of 1802. Around the time of the Napoleonic Wars, the word stretched again. It began to describe armed forces as a whole, giving us phrases like military service, military intelligence, and military history. The terms armed forces and military are often treated as synonyms. Yet in technical use a country's armed forces may include paramilitary bodies such as armed police, a distinction that quietly widens who counts as part of the whole.

• 3. The First Weapon Of War

  ›

  In 2000, the British Army made a striking declaration: "Man is still the first weapon of war." Despite the growing weight of technology, military activity depends above all on people, organized by a command hierarchy split by rank. Those ranks fall in descending order of authority, from officers such as a colonel, to non-commissioned officers such as a sergeant, down to the lowest rank, the private. Senior officers make strategic decisions; soldiers, sailors, marines, and airmen carry them out. Alongside rank, each person holds a trade role, grouped as combat, combat support, or combat service support. Who fills these roles is shaped by recruitment and conscription. Most military personnel are male, and the share of women varies widely, roughly 3 percent in India, 10 percent in the UK, 13 percent in Sweden, 16 percent in the US, and 27 percent in South Africa. Two-thirds of states now take only adults, yet as of 2017-50 states still relied partly on children under 18, usually aged 16 or 17. After the US suspended conscription in 1973, the force drew disproportionately on African American men and men from lower-status backgrounds. A study released in 2020 told a more complicated story, placing US personnel at parity or slightly above the civilian population on income, wealth, and cognitive ability, and finding the most disadvantaged groups now less likely to meet the modern military's requirements.

• 4. Making A Soldier

  ›

  Shaving the head of a new recruit is one of the first acts of basic training, a small ritual that says individuality will be suppressed. Initial training conditions recruits for the demands of military life, including readiness to injure and to kill, and to face mortal danger without fleeing. Uniforms are issued, privacy is denied, first names are prohibited. The daily routine is tightly controlled, with beds to make, boots to polish, and clothes stacked a certain way, and mistakes drawing punishment. Continuous stressors wear down resistance, depriving recruits of sleep, food, or shelter, while instructors shout insults and orders meant to humiliate. The disciplined drill instructor stands as the role model of the ideal soldier. The obligations that follow are long. Full-time service usually runs several years, with two to six years typical in Australia, the UK, and the US, depending on role, branch, and rank. Part-time reserve service lets a recruit keep a civilian job while training at weekends, ready to be called out on operations. Even after leaving, recruits may remain liable for compulsory return to full-time service. Military law also creates offences civilian courts do not recognize, such as absence without leave, desertion, and malingering, with penalties from a summary reprimand to imprisonment after a court martial. Some countries grant a right of conscientious objection when an order is judged immoral or unlawful.

• 5. Thinking Before Fighting

  ›

  "China and India maintain the largest armed forces in the World." Statements like that, and the claim that the US military is the world's strongest, come from military analysis, which assesses the capability of potential aggressors and builds combat modelling to compare forces. The work begins with intelligence, an organization, a system, and a process at once, called military intelligence, or MI. Its difficulty lies in the secrecy of what it seeks and the clandestine way operatives obtain plans for escalation, the start of combat, or an invasion. Groups such as militants or resistance movements may call themselves an Army or a Front, yet none has the structure of a national military, and they often lean on outside national militaries for support. From intelligence flows resource allocation. Defense economics is the effort to fund and sustain militaries, set through a military budget administered by a finance organization, with procurement authorized to buy goods and services. Capability development, the so-called strength, is described here as one of the most complex activities known to humanity. It runs from strategic, operational, and tactical requirements through doctrine, design specifications, force structure, and logistics, all the way to post-conflict demobilization. Among these, the development of military doctrine is called perhaps the most important, because it determines how forces are actually used.

• 6. Strategy Operations Tactics

  ›

  Carl von Clausewitz, the Prussian Major-General, defined military strategy in his book On War as "the employment of battles to gain the end of war." Strategy is the management of forces by a commander-in-chief, a long-term projection of policy whose planning can span weeks but more often months or years. Clausewitz placed political aims above military goals, ensuring civilian control of the military. Beneath strategy sits the operational level, also called operational art, coordinating the details of tactics with the goals of strategy. This concept was pioneered by the German army before and during the Second World War, with planning that runs from one week to a month, executed by Field Armies and Army Corps. Tactics, the third level, concerns engaging and defeating the enemy in direct combat, used by units over hours or days. The written record reaches far back. The Art of War by the Chinese philosopher Sun Tzu, written in the 6th century BCE in 13 chapters, shaped Asian military doctrine and, from the late 19th century, European and United States planning. Julius Caesar wrote commentaries on the Gallic Wars and the Roman Civil war around 50 BC. From the late Roman period came Taktike Theoria by Aelianus Tacticus and De Re Militari by Vegetius, the latter the basis of European tactics until the late 17th century. Its most enduring maxim still echoes: let he who desires peace prepare for war. The grim limit of tactics appeared in the trench warfare of World War I, at Gallipoli and on the Western Front, where attackers had to cross an exposed no man's land under heavy fire.

• 7. Flint To Fission

  ›

  When Stone Age humans first took flint to tip a spear, it was the first example of applying technology to improve a weapon. From there, stone gave way to Bronze Age and Iron Age swords and shields, and ranged weapons arrived with the sling, then the bow and arrow. The domestication of the horse created cavalry, and the wheel brought the chariot and eventually siege engines. Bows grew into composite bows, recurve bows, longbows, and crossbows, while full plate armour encased its wearer in steel built to keep the joints moving. In medieval China, gunpowder was invented and increasingly used in combat. Early vase-like mortars in Europe, alongside armour-piercing arrowheads, ended the dominance of the armoured knight, and gunpowder produced the musket, usable with little training. Industrialization accelerated everything. The machine gun and repeating rifle help explain the high casualty rates of the American Civil War and the decline of melee combat. Breech-loading guns with recoiling barrels allowed quicker aimed fire, and smokeless propellant powders from the 1880s extended artillery ranges. At sea, the internal combustion engine freed naval tactics from sails, and the submarine and torpedo followed. World War I drove the rapid development of tanks; World War II became the most frantic period of weapons development in history. Between 1939 and 1945 came radar, penicillin in military medicine, the guided missile, the jet aircraft, the helicopter, and the nuclear weapon, whose radiation effects were unknown until the early 1950s. After the war, the Cold War institutionalized a constant arms race that continues today, now shaped by guided missiles, space-based reconnaissance, information warfare, and robotic systems such as unmanned combat aerial vehicles. The US military has committed to drawing 50 percent of its energy consumption from alternative sources.

• 8. Society And Conscience

  ›

  Hugo Grotius wrote On the Law of War and Peace in 1625, an early effort to bring a humanitarian approach to warfare, a theme later echoed by Gustavus Adolphus. The relationship between a military and its society is complicated and ever-evolving, swinging between a force seen as vital in time of threat and a burdensome expense met with defence cuts in peace. Militaries often function as societies within societies, with their own communities, economies, education, and medicine, and their reach extends beyond nations through private military companies, or PMCs, hired where police or militaries are absent or distrusted. Control and transparency remain a difficult matter. In some countries only limited information on operations and budgeting reaches the public, yet transparency is crucial to fight corruption, a point made by the Government Defence Anti-corruption Index that Transparency International UK published in 2013. Since 1945, the ethics of warfare have grown to constrain the treatment of prisoners and civilians, primarily through the Geneva Conventions, though these rarely apply when forces act as internal security during political conflict. International conventions define war crimes and provide for their prosecution, and individual countries keep their own codes, such as the United States' Uniform Code of Military Justice. Sometimes military action is justified by a humanitarian cause, such as defending refugees in disaster relief, an idea named military humanism, which leaves the oldest profession in human history still arguing over when force is right.
