Technological evolution


New weapons development can dramatically alter the face of war, the cost of warfare, the preparations, and the training of soldiers and leaders. A rule of thumb is that if your enemy has a potentially war winning weapon, you have to either match it or neutralize it.

Ancient era
Chariots originated around 2000 BC. The chariot was an effective, fast weapon; while one man controlled the maneuvering of the chariot, a second bowman could shoot arrows at enemy soldiers. These became crucial to the maintenance of several governments, including the New Egyptian Kingdom and the Shang dynasty and the nation states of early to mid Zhou dynasty.

Some of the military unit types and technologies which were developed in the ancient world are:
 * Slinger
 * Hoplite
 * Auxiliaries
 * Infantry
 * Archery
 * Chariots
 * Cavalry

For settled agrarian civilizations, the infantry became the core of military action. The infantry started as opposing armed groups of soldiers underneath commanders. The Greeks and early Romans used rigid, heavily armed phalanxes. The Macedonians and Hellenistic states would adopt phalanx formations with sarissa pikemen. The Romans would later adopt more flexible maniples from their neighbors which made them extremely successful in the field of battle. The kingdoms of the Warring States in East Asia also adopted infantry combat, a transition from chariot warfare from centuries earlier.

Archers were a major component of many ancient armies, notably those of the Persians, Scythians, Egyptians, Nubians, Indians, Koreans, Chinese, and Japanese.

Cavalry became an important tool. In the Sicilian Expedition, led by Athens in an attempt to subdue Syracuse, the well-trained Syracusan cavalry became crucial to the success of the Syracusans. Macedonian Alexander the Great effectively deployed his cavalry forces to secure victories. In battles such as the Battle of Cannae of the Second Punic War, and the Battle of Carrhae of the Roman-Persian Wars, the importance of the cavalry would be repeated.

There were also horse archers, who had the ability to shoot on horseback – the Parthians, Scythians, Mongols, and other various steppe people were especially fearsome with this tactic. By the 3rd–4th century AD, heavily armored cavalry became widely adopted by the Parthians, Sasanians, Byzantines, Eastern Han dynasty and Three Kingdoms, etc.

The early Indo-Iranians developed the use of chariots in warfare. The scythed chariot was later invented in India and soon adopted by the Persians.

War elephants were sometimes deployed for fighting in ancient warfare. They were first used in India and later adopted by the Persians. War elephants were also used in the Battle of the Hydaspes River, and by Hannibal in the Second Punic War against the Romans.

Naval warfare was often crucial to military success. Early navies used sailing ships without cannons; often the goal was to ram the enemy ships and cause them to sink. There was human oar power, often using slaves, built up to ramming speed. Galleys were used in the 3rd millennium BC by the Cretans. The Greeks later advanced these ships.

In 1210 BC, the first recorded naval battle was fought between Suppiluliuma II, king of the Hittites, and Cyprus, which was defeated. In the Greco-Persian Wars, the navy became of increasing importance.

Triremes were involved in more complicated sea-land operations. Themistocles helped to build up a stronger Greek navy, composed of 310 ships, and defeated the Persians at the Battle of Salamis, ending the Persian invasion of Greece.

In the First Punic War, the war between Carthage and Rome started with an advantage to Carthage because of their naval experience. A Roman fleet was built in 261 BC, with the addition of the corvus that allowed Roman soldiers on board the ships to board the enemy ships. The bridge would prove effective at the Battle of Mylae, resulting in a Roman victory.

The Vikings, in the 8th century AD, invented a ship propelled by oars with a dragon decorating the prow, hence called the Drakkar. The 12th century AD Song Dynasty invented ships with watertight bulk head compartments while the 2nd century BC Han dynasty invented rudders and sculled oars for their warships.

Fortifications are important in warfare. Early hill-forts were used to protect inhabitants in the Iron Age. They were primitive forts surrounded by ditches filled with water. Forts were then built out of mud bricks, stones, wood, and other available materials. Romans used rectangular fortresses built out of wood and stone. As long as there have been fortifications, there have been contraptions to break in, dating back to the times of Romans and earlier. Siege warfare is often necessary to capture forts.

Middle-ages
Some of the military unit types and technologies which were used in the medieval period are:
 * Artillery
 * Cataphract
 * Condottieri
 * Fyrd
 * Rashidun
 * Mobile guard
 * Mamluk
 * Janissary
 * Knight (see also: Chivalry)
 * Crossbow
 * Pikeman
 * Samurai
 * Sipahi
 * Trebuchet

Bows and arrows were often used by combatants. Egyptians shot arrows from chariots effectively. The crossbow was developed around 500 BC in China, and was used a lot in the Middle Ages. The English/Welsh longbow from the 12th century also became important in the Middle Ages. It helped to give the English a large early advantage in the Hundred Years' War, even though the English were eventually defeated. The Battle of Crécy and the Battle of Agincourt are excellent examples of how to destroy an enemy using a longbow. It dominated battlefields for over a century.

The rise of gunpowder
In the 10th century, the invention of gunpowder led to many new weapons that were improved over time. Black powder was used in China since the 4th century, but it was not used as a weapon until the 11th century. Until the mid-15th century, guns were held in one hand, while the explosive charge was ignited by the other hand. Then came the matchlock, which was used widely until around the 1720s. Leonardo da Vinci made drawings of the wheel lock which made its own sparks. Eventually, the matchlock was replaced by the flintlock. Cannons were first used in Europe in the early 14th century, and played a vital role in the Hundred Years' War. The first cannons were simply welded metal bars in the form of a cylinder, and the first cannonballs were made of stone. By 1346, at the Battle of Crécy, the cannon had been used; at the Battle of Agincourt they would be used again.

At the beginning of the 16th century, the first European fire ships were used. Ships were filled with flammable materials, set on fire, and sent to enemy lines. This tactic was successfully used by Francis Drake to scatter the Spanish Armada at the Battle of Gravelines, and would later be used by the Chinese, Russians, Greeks, and several other countries in naval battles.

Naval mines were invented in the 17th century, though they were not used in great numbers until the American Civil War. They were used heavily in the First and Second World Wars. Air-deployed naval mines were used to mine the North Vietnamese port of Haiphong during the Vietnam War. The Iraqi Navy of Saddam Hussein used naval mines extensively during the Tanker War, as part of the Iran–Iraq War.

The first navigable submarine was built in 1624 by Cornelius Drebbel, it could cruise at a depth of 15 feet (5 m). However, the first military submarine was constructed in 1885 by Isaac Peral.

The Turtle was developed by David Bushnell during the American Revolution. Robert Fulton then improved the submarine design by creating the Nautilus.

The Howitzer, a type of field artillery, was developed in the 17th century to fire high trajectory explosive shells at targets that could not be reached by flat trajectory projectiles.

Organizational changes resulting in better training and intercommunication, made the concept combined arms possible, allowing the use of infantry, cavalry, and artillery in a coordinated way.

Bayonets also became of wide usage to infantry soldiers. Bayonet is named after Bayonne, France where it was first manufactured in the 16th century. It is used often in infantry charges to fight in hand-to-hand combat. General Jean Martinet introduced the bayonet to the French army. They were used heavily in the American Civil War, and continued to be used in modern wars like the Invasion of Iraq.

Balloons were first used in warfare at the end of the 18th century. It was first introduced in Paris of 1783; the first balloon traveled over 5 miles (8 km). Previously military scouts could only see from high points on the ground, or from the mast of a ship. Now they could be high in the sky, signalling to troops on the ground. This made it much more difficult for troop movements to go unobserved.

At the end of the 18th century, iron-cased artillery rockets were successfully used militarily in India against the British by Tipu Sultan of the Kingdom of Mysore during the Anglo-Mysore Wars. Rockets were generally inaccurate at that time, though William Hale, in 1844, was able to develop a better rocket. The new rocket no longer needed the rocket stick, and had a higher accuracy.

In the 1860s there were a series of advancements in rifles. The first repeating rifle was designed in 1860 by a company bought out by Winchester, which made new and improved versions. Springfield rifles arrived in the mid-19th century also. Machine guns arrived in the late 19th century. Automatic rifles and light machine guns first arrived at the beginning of the 20th century.

In the later part of the 19th century, the self-propelled torpedo was developed. The HNoMS Rap was the world's first torpedo boat.

Modern technologies
At the start of the World Wars, various nations had developed weapons that were a surprise to their adversaries, leading to a need to learn from this, and alter how to combat them. Flame throwers were first used in the First World War. The French were the first to introduce the armored car in 1902. Then in 1918, the British produced the first armored troop carrier. Many early tanks were proof of concept but impractical until further development. In World War I, the British and French held a crucial advantage due to their superiority in tanks; the Germans had only a few dozen A7V tanks, as well as 170 captured tanks. The British and French both had several hundred each. The French tanks included the 13 ton Schneider-Creusot, with a 75 mm gun, and the British had the Mark IV and Mark V tanks.

On December 17, 1903, the Wright Brothers performed the first controlled, powered, heavier-than-air flight; it went 39 meters (120 ft). In 1907, the first helicopter flew, but it wasn't practical for usage. Aviation became important in World War I, in which several aces gained fame. In 1911 an aircraft took off from a warship for the first time. Landings on a cruiser were another matter. This led to the development of an aircraft carrier with a decent unobstructed flight deck.

Chemical warfare exploded into the public consciousness in World War I but may have been used in earlier wars without as much human attention. The Germans used gas-filled shells at the Battle of Bolimov on January 3, 1915. These were not lethal, however. In April 1915, the Germans developed a chlorine gas that was highly lethal, and used it to moderate effect at the Second Battle of Ypres. Gas masks were invented in matter of weeks, and poison gas proved ineffective at winning battles. It was made illegal by all nations in the 1920s.

World War II gave rise to even more technology. The worth of the aircraft carrier was proved in the battles between the United States and Japan like the Battle of Midway. Radar was independently invented by the Allies and Axis powers. It used radio waves to detect objects. Molotov cocktails were invented by General Franco in the Spanish Civil War, directing the Nationalists to use them against Soviet tanks in the assault on Toledo. The atomic bomb was developed by the Manhattan Project and dropped on Hiroshima and Nagasaki in 1945, quickly ending World War II.

During the Cold War, the main powers engaged in a Nuclear arms race. In the space race, both nations attempted to launch human beings into space to the moon. Other technological advances centered on intelligence (like the spy satellite) and missiles (ballistic missiles, cruise missiles). Nuclear submarine, invented in 1955. This meant submarines no longer had to surface as often, and could run more quietly. They evolved into becoming underwater missile platforms.
