Dragoon in the context of "Freikorps"

Historically, cavalry (from the French word cavalerie, itself derived from cheval meaning "horse") are groups of soldiers or warriors who fight mounted on horseback. Until the 20th century, cavalry were the most mobile of the combat arms, operating as light cavalry in the roles of reconnaissance, screening, and skirmishing, or as heavy cavalry for decisive economy of force and shock attacks. An individual soldier in the cavalry is known by a number of designations depending on era and tactics, such as a cavalryman, horseman, trooper, cataphract, knight, drabant, hussar, uhlan, mamluk, cuirassier, lancer, dragoon, samurai or horse archer. The designation of cavalry was not usually given to any military forces that used other animals or platforms for mounts, such as chariots, camels or elephants. Infantry who moved on horseback, but dismounted to fight on foot, were known in the early 17th to the early 18th century as dragoons, a class of mounted infantry which in most armies later evolved into standard cavalry while retaining their historic designation.

Cavalry had the advantage of improved mobility, and a soldier fighting from horseback also had the advantages of greater height, speed, and inertial mass over an opponent on foot. Another element of horse mounted warfare is the psychological impact a mounted soldier can inflict on an opponent.

The Dragonnades was a policy implemented by Louis XIV in 1681 to force French Protestants known as Huguenots to convert to Catholicism. It involved the billeting of dragoons of the French Royal Army in Huguenot households, with the soldiers being given implied permission to mistreat the inhabitants and damage or steal their possessions. Soldiers employed as part of this policy were derisively referred to as "missionary dragoons".

Mounted archery is a form of archery that involves shooting arrows while on horseback. A horse archer is a person who does mounted archery. Archery has occasionally been used from the backs of other riding animals. In large open areas, mounted archery was a highly successful technique for hunting, for protecting herds, and for war. It was a defining characteristic of the Eurasian nomads during antiquity and the medieval period, as well as the Iranian peoples such as the Alans, Sarmatians, Cimmerians, Scythians, Massagetae, Parthians, and Persians in Antiquity, and by the Hungarians, Mongols, Chinese, and Turkic peoples during the Middle Ages. The expansion of these cultures have had a great influence on other geographical regions including Eastern Europe, West Asia, and East Asia. In East Asia, horse archery came to be particularly honored in the samurai tradition of Japan, where horse archery is called Yabusame.

The term mounted archer occurs in medieval English sources to describe a soldier who rode to battle but who dismounted to shoot, similar to the later firearm-equipped dragoons. Horse archer is the term used more specifically to describe a warrior who shoots from the saddle at the gallop. Another term, "horseback archery", has crept into modern use.

Mounted infantry were infantry who rode horses instead of marching. Unlike cavalry, mounted infantry dismounted to fight on foot. The original dragoons were essentially mounted infantry. According to the Encyclopædia Britannica Eleventh Edition (1910–1911), "Mounted rifles are half cavalry, mounted infantry merely specially mobile infantry." Today, with motor vehicles having replaced horses for military transport, the motorized infantry are in some respects successors to mounted infantry.

The Battle of Gonzales was the first military engagement of the Texas Revolution. It was fought near Gonzales, Texas, on October 2, 1835, between rebellious Texian settlers and a detachment of Mexican Army soldiers. In 1831, Green DeWitt asked the Mexican authorities to lend the Gonzales colonists a cannon to help protect them from frequent Comanche raids. One was supplied, on the condition that the cannon would be returned to the Mexicans on request. Over the next four years, the political situation in Mexico deteriorated, and in 1835 several states revolted. As the unrest spread, Colonel Domingo de Ugartechea, the commander of all Mexican troops in Texas, felt it unwise to leave the residents of Gonzales with a weapon and requested the return of the cannon.

When the initial request was refused, Ugartechea sent 100 dragoons to retrieve the cannon. The soldiers neared Gonzales on September 29, but the colonists used a variety of excuses to keep them from the town, while secretly sending messengers to request assistance from nearby communities. Within two days, up to 140 Texians gathered in Gonzales, all determined not to give up the cannon. On October 1, settlers voted to initiate a fight. Mexican soldiers opened fire as Texians approached their camp in the early hours of October 2. After several hours of desultory firing, the Mexican soldiers withdrew. Although the skirmish had little military significance, it marked a clear break between the colonists and the Mexican government and is considered to have been the start of the Texas Revolution. News of the skirmish spread throughout the United States, where it was often referred to as the "Lexington of Texas".

Mobile infantry refers to infantry that has superior mobility to traditional infantry, the latter being expected to march into battle. Mobile infantry, on the other hand, is better equipped with vehicles for transportation to and on the battlefield. Examples include:

• Mechanized infantry, equipped with armored personnel carriers (APCs) or infantry fighting vehicles (IFVs)
• Motorized infantry, employing trucks or other vehicles, but not APCs or IFVs
• Mounted infantry, riding horses. Dragoons were originally mounted infantry
• Bicycle infantry, specifically employing bicycles for movement
• Airmobile infantry, carried by helicopter or other aircraft.
