Lancer
A lancer was a type of cavalryman who fought with a lance. Lances were used for mounted warfare in Assyria as early as and subsequently by Persia, India, Egypt, China, Greece, and Rome. The weapon was widely used throughout Eurasia during the Middle Ages and the Renaissance by heavy cavalry, before being adopted later on by light cavalry. 17th, 18th, and 19th century lancers. The lancer (called "ułan" in Polish and "Ulan" in German) had become a common sight in the majority of European, Ottoman, and Indian cavalry forces during this time, but, with the exception of the Ottoman  troops, they increasingly discarded the heavy armour to give greater freedom of movement in combat. The Polish "winged" lancers were amongst the last European units to abandon their armour. There was debate over the value of the lance in mounted combat during the 17th and 18th centuries, with most armies having very few lancer units by the beginning of the 19th century. However, during the Napoleonic Wars, lancers were to be seen in many of the combatant nations as their value in shock tactics became clear. During the wars, the Poles became a ready source of recruitment for several armies , willingly or unwillingly. Polish lancers served with distinction in the Austrian, Prussian, Russian, and French armies, most famously in Napoleon's French Imperial Guard as the "1er Regiment de Chevau-Legers-Lanciers de la Garde Impériale". At the Battle of Waterloo, French lances were "nearly three meters (about nine feet, eight inches) long, weighed three kilograms (about six pounds, six ounces), and had a steel point on a wooden staff," according to historian Alessandro Barbero. He adds that they were "terrifyingly efficient." Commander of the French 1st Corps, 4th Division General Durutte, who saw the battle from the high ground  in front of Papelotte, would write later, "I had never before realized the great superiority of the lance over the sword." Although having substantial impact in the charge, lancers could be vulnerable to other cavalry at close quarters, where the lance proved a clumsy and easily deflected weapon when employed against sabres. By the late 19th century, many cavalry regiments in European and Asian armies were composed of troopers with lances, as primary weapons, in the front rank and horsemen with sabres only in the second: the lances for the initial shock and sabres for the ensuing mêlée. Lancers equipment . Lancers typically wore a double-breasted jacket ("kurtka") with a coloured panel at the front ("plastron"), a coloured band of cloth ("sash"), and a square-topped cap ("czapka"). Their lance usually had a small swallow-tailed flag ("pennon"), just below the lance head. The pennons were normally removed or wrapped in a canvas cover on active service. With the improved range and accuracy of infantry muskets and rifles, the high profile presented by lancers with their conspicuous weapons being carried became a problem. The ułans or uhlans, as lancers are known in the Polish and German languages respectively, were trained  to lower their lances when scouting on hill-tops. 20th century lancers. In 1914, lances were still being carried by regiments in the British, Indian, French, Prussian, Italian, Chilean, Portuguese, Japanese, Spanish, Ottoman, Belgian, Argentinean, and Russian armies, amongst others. Almost all German cavalry branches (cuirassiers, hussars, dragoons, and uhlans) retained a steel lance ("stahlrohrlanze") as their primary weapon. As late as 1914, half of the troopers in each Russian regular cavalry regiment (hussars, uhlans, and dragoons) carried lances on active service, as did all cossacks. The British cavalry lost the lance for all but ceremonial use in 1903, following  the Second Boer War; but a backlash led to its reintroduction as an active service weapon from 1909 to 1928. The French army did not have lancer regiments as such, but steel lances in length were carried by the twenty-six dragoon regiments and some light cavalry units in 1914. The French had earlier tested the Indian bamboo lances used by the British cavalry, but had rated them as being too fragile for the shock of encounter. The six Italian "lancieri" regiments still in existence until 1920 and carried the 1870 model of ashwood lance, noted for its balance and  manageability. Prior to the outbreak of World War I, there had been controversy as to whether lances or sabres were the more effective "armes blanches" (i.e., edged weapons) for cavalry, but neither proved a match for modern firearms. Some armies continued to use lances throughout this war, but they seldom saw use on the Western Front after initial clashes in France and Belgium in 1914. On the Eastern Front, mounted cavalry still had a role and lances saw limited use by the Russian, German, and Austrian armies. During the 1920s and 1930s, the use of lances ceased for active service  in most armies. The German cavalry retained the lance as a service weapon until 1927, as did the British cavalry until 1928. Some other armies retained lance-armed cavalry units for ceremonial purposes only. The Polish cavalry did not discard the lance as a weapon until 1934 or 1937 and continued to use it for training and ceremonial purposes until the outbreak of World War II. Current lancer units. Some modern armored cavalry units are still designated as lancer regiments for historical and ceremonial reasons. There are examples in the armies of Spain (the King's Lancers Troop of the  Royal Guard's Escort Squadron and the Bourbon's Lancers Group of the 11th Cavalry Regiment), United Kingdom (Royal Lancers), India (2nd Lancers (Gardner's Horse) and 20th Lancers), Belgium, Portugal (2nd Lancers Regiment), Pakistan, Italy (5th Lancieri di Novara, 6th Lancieri di Aosta, 8th Lancieri di Montebello), Australia (12th/16th Hunter River Lancers, 1st/15th Royal New South Wales Lancers), Argentina (2nd Tank Cavalry Regiment "General Paz's Lancers"), and Chile (5th Cavalry Regiment "Lancers"). Although not classified as lancers, the Brazilian Army's "Dragões da Independência" (1st Guards Regiment) and the elite soldiers of the Colombian National Army are called  Lanceros. The Portuguese National Republican Guard horse squadrons carry lances on mounted parades, as do many cavalry regiments in South America such as Chile, Argentina, Bolivia, and Peru. The modern Italian Regiment "Lancieri di Montebello" (8th) parade detachments armed with the lances carried as combat weapons until 1920.
