Grenadier A grenadier ( from French , derived from the word grenade ) was originally a specialized soldier , first established as a distinct role in the mid - to - late 17th century , for the throwing of grenades and sometimes assault operations . At that time grenadiers were chosen from the strongest and largest soldiers . By the 18th century , the throwing of grenades was no longer relevant , but grenadiers were still chosen for being the most physically powerful soldiers and would lead assaults in the field of battle . Grenadiers would also often lead the storming of fortification breaches in siege warfare , although this role was more usually fulfilled by all - arm units of volunteers called forlorn hope s , and might also be fulfilled by sapper s or pioneer s . Certain countries such as France ( Grenadiers à Cheval de la Garde Impériale ) and Argentina ( Regiment of Mounted Grenadiers ) established units of Horse Grenadiers and for a time the British Army had Horse Grenadier Guards . Like their infantry grenadier counterparts , these horse - mounted soldiers were chosen for their size and strength ( heavy cavalry ) . Origins . The concept of throwing grenades may go back to the Ming Dynasty , when Chinese soldiers on the Great Wall were reported to be using this weapon . The earliest references to these grenade - throwing soldiers in Western armies come from Austria and Spain . References also appear in England during the English Civil War . However , it was King Louis XIV of France who made the grenadier an official type of soldier and company during his army reforms late in the 17th century . According to René Chartrand , Lt . Col . Jean Martinet introduced the idea of having men detailed to throw grenades in the " Régiment du Roi " in 1667 . In May 1677 the English Army ordered that two soldiers of every Guards Regiment were to be trained as grenadiers ; in April 1678 it was ordered that a company of grenadiers be added to the senior eight regiments of foot of the army . On the 29th of June the diarist John Evelyn saw them at a war games encampment at Hounslow , near London : Now were brought into service a new sort of soldier called Grenadiers , who were dexterous in flinging hand grenadoes , every one having a pouch full ; they had furred caps with coped crowns like Janizaries , which made them look very fierce , and some had long hoods hanging down behind , as we picture fools . Their clothing being likewise piebald , yellow and red . Grenades . The first grenades were small iron spheres filled with gunpowder fused with a length of slow - match , roughly the size of a cricket ball or a baseball . The grenadiers had to be tall and strong enough to hurl these heavy objects far enough so as not to harm themselves or their comrades , and disciplined enough to stand at the forefront of the fight , light the fuse and throw at the appropriate moment to minimize the ability of an enemy to throw the grenade back . Understandably , such requirements led to grenadiers being regarded as an elite fighting force . Early distinctions of dress and equipment . The wide hats with broad brims characteristic of infantry during the late 17th century were discarded and replaced with caps . This was originally to allow the grenadier to sling his musket over his back with greater ease while throwing grenades ( initially , only these troops were provided with slings ) . Additionally , a brimless hat permitted the grenadier greater ease in throwing the grenade overhand . By 1700 , grenadiers in the English and other armies had adopted a cap in the shape of a bishop ' s mitre , usually decorated with the regimental insignia in embroidered cloth . In addition to grenades , they were equipped with contemporary longarms . The uniform included a belt tube that held the match for lighting the fuse ; this feature was retained in later grenadier uniforms . Elite status in the 18th century . Grenade usage declined significantly in the early 18th century , a fact that can be attributed to the improved effectiveness of massive infantry line tactics and flintlock technology . However , the need for elite assault troops remained , and the existing grenadier companies were used for this purpose . As noted , above average physical size had been considered important for the original grenadiers and , in principle , height and strength remained the basis of selection for these picked companies . In the British regiments of foot during the 18th century the preference was , however , to draw on steady veterans for appointment to individual vacancies in a grenadier company ( one of the eight companies comprising each regiment ) . The traditional criterion of size was only resorted to when newly raised regiments required a quick sorting of a mass of new recruits . Transferral to a grenadier company generally meant both enhanced status and an increase in subsistence pay . Whether for reasons of appearance or reputation , grenadiers tended to be the showpiece troops of their respective armies . In the Spanish Army of the early 19th century , for example , grenadier companies were excused routine duties such as town patrols but were expected to provide guards at the headquarters and residences of senior officers . When a regiment was in line formation the grenadiers were always the company which formed on the right flank . In the British Army , when trooping the colour , the " British Grenadiers March " is played no matter which regiment is on the parade ground , as the colour party stands at the right - hand end of the line , as every regiment formerly had a company of grenadiers at the right of their formation . Headgear . As noted above , grenadiers were distinguished by their head - gear from the ordinary musketeers ( or " Hatmen " ) who made up the bulk of each regiment of foot . While there were some exceptions , the most typical grenadier headdress was either the mitre cap or the bearskin . Both began to appear in various armies during the second half of the 17th century because grenadiers were impeded by the wide brimmed infantry hats of the period when throwing grenades . The cloth caps worn by the original grenadiers in European armies during the 17th century were frequently trimmed with fur . The practice fell into disuse until the second half of the 18th century when grenadiers in the British , Spanish and French armies began wearing high fur hats with cloth tops and , sometimes , ornamental front plates . The purpose appears to have been to add to the apparent height and impressive appearance of these troops both on the parade ground and the battlefield . The mitre cap , whether in stiffened cloth or metal , had become the distinguishing feature of the grenadier in the armies of Britain , Russia , Prussia and most German states during the late 17th and early 18th centuries . Spanish , Austrian and French grenadiers favoured high fur hats with long coloured cloth hoods ( " " bags " " ) to them . The mitre was gradually replaced by bearskin hats in other armies and by 1914 it only survived in three regiments of the Prussian and Russian Imperial Guards . Russian grenadiers had worn their brass fronted mitre hats on active service until 1809 and some of these preserved for parade wear by the Pavlovsky Guards until 1914 still had dents or holes from musket balls . Some have survived for display in modern museums and collections . While Northern - European armies such as Britain , Russia , Sweden and various German states ( perhaps most famously Prussia ) wore the mitre cap , southern countries such as France , Spain , Austria , Portugal and various Italian states preferred the bearskin . By 1768 Britain had adopted the bearskin . The shape and appearance of fur hats differed according to period and country . While France used smaller bearskins , Spain preferred towering ones with long flowing bags , and while Britain had its tall cloth mitres with lacing and braiding , Russia would sport equally tall leather helmets with brass front - plates . The first headdresses were fairly low , and in the case of Spain and Austria sometimes contained elements from both mitres and bearskins . At the beginning of the 18th century and briefly during the 1770s , French grenadiers wore tricorne hats , rather than either the mitre or fur cap . Gradually , both began to increase in size and decoration , now showing devices such as pompoms , cords , badges , front - plates , plumes , braiding and also various national heraldic symbols . By the advent of the Napoleonic Wars , both mitres and fur hats had began to fall out of use in favour of the shako . Two major exceptions were France ' s Grande Armée ( although in 1812 , regulations changed grenadier uniforms to those more similar to the ones of fusilier s , except in guard regiments ) and the Austrian Army . After the Battle of Friedland in 1807 , because of their distinguished performance , Russia ' s Pavlovsk Regiment were allowed to keep their mitre caps and were admitted to the Imperial Guard . During the Napoleonic Wars , British grenadiers had normally worn the bearskin only for full dress when at home , since the fur was found to deteriorate rapidly on overseas service . Following their role in the defeat of the French Old Guard at the Battle of Waterloo , the 1st Foot Guards was renamed the Grenadier Guards and all companies of the regiment adopted the bearskin . All British infantry grenadiers retained the fur headdress for parade dress until shortly before the Crimean War , where it was only worn by foot guard regiments . Grenadier companies . From the 17th Century to the mid 19th centuries the " Foot " or infantry regiments of the British and several other armies comprised ten companies ; eight of them " Battalion " or " Centre " companies , and two " Flank Companies " consisting of one Grenadier and one Light or Light Infantry Company . In the United States an Act of Congress made on 8 May 1792 directed that for every infantry battalion there should be one company of grenadiers , riflemen , or light infantry . On occasion the grenadier and light companies could be " brigaded " together into separate grenadier and light infantry battalions for assaults or skirmishing respectively . Each of the line infantry regiments of the Austrian Army of this period included a grenadier division of two companies , separate from the fusilier companies which made up the bulk of the unit . The grenadier companies were frequently detached from the parent regiment and grouped into composite grenadier battalions for a particular campaign or purpose . The Russian Imperial Army of the 18th century followed a different line of development . Prior to 1731 grenadiers made up five separate regiments . These were disbanded prior to the outbreak of war with Turkey and picked infantrymen were transferred to one of two grenadier companies incorporated in each ( two - battalion ) line infantry regiment . In 1756 each of these grenadier companies was brought together in four permanent grenadier regiments . This policy of maintaining a separate corps of grenadiers continued until the Russian Revolution of 1917 . With the standardisation of training and tactics , the need for separate grenadier companies at regimental level had passed by the mid - 19th century and the British , French and Austrian armies phased out these sub - units between 1850 and 1862 . Grenadier regiments . The term grenadier was retained or adopted by various elite infantry units , including Potsdam Grenadiers , the Granatieri di Sardegna ( Grenadiers of Sardinia ) in Italy , the Foot Grenadiers , Fusilier - Grenadiers , Tirailleur - Grenadiers and Horse Grenadiers of the French Imperial Guard , the Imperial Russia n Grenadier Leib Guard s Regiment , Britain ' s Grenadier Guards and the 101st Grenadiers . The latter was part of the British Indian Army and claimed to be the first and oldest grenadier regiment ( as opposed to grenadier companies ) in the British Empire . In 1747 the grenadier companies of a number of disbanded French infantry regiments were brought together to form a single permanent unit - the " Grenadiers de France " . During the American Revolution of 1775 - 1783 , the Connecticut 1st Company Governor ' s Foot Guard s and the 11th Regiment of Connecticut Militia had grenadier companies . . New York City also had a Grenadier unit , as did South Carolina - the elite 1st South Carolina Regiment , raised and commanded by Charles Cotesworth Pinckney . In Mexico Antonio López de Santa Anna created the Grenadier Guards of the Supreme Power on 7 Dec 1841 . The formation remained in service until 1847 . A Toronto militia unit was renamed the 10th Royal Grenadiers then later became the Royal Regiment of Canada . In 1914 the Imperial German and Russian Armies included a number of grenadier regiments . In the Russian Army these comprised the Grenadier Guards Regiment as well as the Grenadier Corps of sixteen regiments . Five regiments of the Prussian Guard were designated as Garde - Grenadiers and there were an additional fourteen regiment of grenadiers amongst the line infantry of the German Empire . In both Russian and German armies the grenadier regiments were considered a historic elite , distinguished by distinctions such as plumed helmets in full dress or special braiding . Their role and training however no longer differed from that of the rest of the infantry . Modern usage . In modern times , regiments using the name grenadiers are effectively indistinguishable from other infantry , especially when hand grenade s , RPG s , and other types of explosive arms have become standard - issue weaponry ; however , such regiments retain at least the tradition of their elite past . Grenadier can also refer to soldiers utilizing grenade launcher s , including those mounted on rifles . During World War I a proposal to designate specialist grenade launching units in the British Army as grenadiers was vetoed by the Grenadier Guards who considered that they now had exclusive rights to the ancient distinction , and the term " bomber " was substituted . During World War I , German troops referred to as pioneer s , who were early combat engineers or sapper s and stormtrooper s began using two types of hand grenades in trench warfare operations against the French to clear opposing trenches of troops . The more effective of the two was the so - called " potato masher " " Stielhandgranate " , which were stick grenades . The term " Panzergrenadier " was adopted in the German " Wehrmacht " to describe mechanized heavy infantry elements whose greater protection and mobility allowed them to keep pace with ( and provide intimate protection to ) armoured units and formations . This designation reflects the traditional role of grenadiers as shock troops . The term in today ' s " Bundeswehr " refer to mechanized infantry . When parachute units were first created in the United States Army , the Air Corps desired them to be under their control and to be designated " air grenadiers " . The last known unit to serve as grenadiers , and employing grenades as their weapons , was a special " Grenadier brigade " formed by the Red Army within the 4th Army during the Tikhvin defensive operation in October 1941 . It was a measure taken because of lack of firearms , and the commander of the brigade was appropriately General Major G . T . Timofeyev who had served in one of the Russian Imperial Army ' s grenadier regiments during the First World War . In the Vietnam War US squads usually had at least one soldier whose role was that of a grenadier . He was usually armed with an M79 grenade launcher , although towards the end of the war it was replaced with an XM148 grenade launcher underslinging an M16 rifle in very small numbers . In infantry squads the grenadier was dedicated to his weapon , meaning that he usually carried only the M79 and a Colt 1911 side arm . In some cases , grenadiers were not even issued this sidearm . The M79 was designed to bridge the gap between the maximum throwing range of a grenade and the minimum distance of mortar fire . It also allowed the use of various rounds , notably high explosive , buckshot , flechette , smoke grenades and parachute flares . Modern US squads have continued the concept of the grenadier armed with an M203 grenade launcher or M320 attached to an M16 or M4 . Argentina . The Argentine Army still maintains a prestigious unit known as the Horse Grenadiers Regiment ( " Regimiento de Granaderos a Caballo " ) - - actually a squadron - strength formation — which serves as the Presidential ceremonial escort and guard unit . The regiment was founded in 1903 as a recreation of a unit which existed from 1813 to 1826 under the leadership of national hero General José de San Martín . Unlike most other units which carried the title of " grenadiers " , the Argentine Grenadiers are a cavalry unit , and continue to mount horses for ceremonial purposes , as well as carrying lances and cavalry sabers . Belgium . See : Regiment Carabiniers Prins Boudewijn – Grenadiers The Belgian Army retains two regiments of grenadiers based in Brussels . First raised in 1837 from companies drawn from the line infantry of the newly independent kingdom , these troops served with distinction in both World Wars . In peacetime they had a ceremonial role which corresponded to that of royal guards in other armies . In 1999 the historic blue and red full dress worn prior to World War I was reintroduced for limited wear , although the tall bearskin headdress is now made of synthetic material . Canada . The Canadian Grenadier Guards is one of the longest serving units in the Canadian reserve , it still continues today , both in its reserve role and as a ceremonial guard at Rideau Hall among other places of symbolic importance . The 10th Royal Grenadiers later became the Royal Regiment of Canada with tradition surviving in a grenadier company . Chile . The same case of the Mounted Grenadier Regiment in Argentina also applies to its western neighbor Chile . The 1st Armored Cavalry Regiment " Grenadiers " ( " Regimiento de Caballeria Blindada n . 1 " Granaderos " " ) of the Chilean Army is active since 1827 , has fought in every major battle of the Chilean Army in the 19th century and since 1840 and 1907 has served as the Escort Regiment to the President of Chile in every important national occasion . This regiment is named after General Manuel Bulnes Prieto , the founder of the regiment , who led the Chilean Army to victory in the War of the Peru - Bolivia Confederation in the crucial Battle of Yungay in 1839 , which signaled the confederation ' s demise . The Chilean Grenadiers ' uniforms are similar to the full " Feldgrau " uniforms of the Chilean Army , but adapted for the cavalry , and like their Argentine counterparts , carry lances but not cavalry sabers , which are reserved for officers and the mounted colors guard escort . Ecuador . The " Tarqui Grenadiers " serve as the Presidential Escort Squadron for the President of Ecuador . The unit stands guard at Quito ' s Carondelet Palace and retains the uniform worn during the Battle of Tarqui of 1829 . France . While the French army has not included any grenadiers since 1870 , the grenade badge is still a distinctive mark of the Foreign Legion , the National Gendarmerie and the French Customs which was a military unit until 1940 . Germany . In the German Army Armoured Grenadier ( " Panzergrenadier " ) is the lowest rank in the " Panzergrenadiere " branch of service which translates into mechanized infantry . Furthermore grenadier is the lowest rank in the army part of the guard battalion ( " Wachbattaillon " ) . India . The Grenadiers is a regiment of the Indian Army , formerly known as the 4th Bombay Grenadiers when part of the British Indian Army . It is the oldest active and continuing Grenadier regiment in the Commonwealth of Nations . Italy . The 1st Grenadiers of Sardinia regiment ( " Reggimento Granatieri di Sardegna " ) is currently part of the mechanized infantry brigade with the same name in the Italian Army . This unit traces its history back to a guards regiment raised in 1659 and is made up predominantly of one year volunteers . Historically , as the senior regiment in the Piedmontese and Italian armies the Grenadiers of Sardinia took the tallest recruits of each intake . On ceremonial occasions the Italian Grenadiers parade in their 19th century blue uniforms and fur headdresses . The 1st Grenadiers of Sardinia regiment is currently ( 2010 ) the only infantry regiment of the Italian Army with two battalions ( 1st " Assietta " and 2nd " Cengio " Grenadiers battalions ) , and it is likely that in the near future its 2nd battalion will be detached to re - activate the 2nd Sardinia Grenadiers Regiment . Mexico . In Mexico , Grenadiers ( " Granaderos " ) are armored specialist police units used for anti - riot duties and other security roles . Netherlands . The modern Dutch Army maintains a regiment of Guard Grenadiers who retain the bearskin headdress of the early 19th century . This regiment has been amalgamated with the Jager Guards to form the " " Garderegiment Grenadiers en Jagers " " Two of its companies are Jagers ( riflemen ) , the other two are grenadiers ; it wears the maroon beret and is an air assault and para trained unit . Norway . In the Norwegian Army , grenadier ( Norwegian : " grenader " ) is used as a rank , the lowest enlisted below sergeant , to distinguish professional soldiers from conscripts . The grenadiers are employed for positions requiring more experience and / or professional presence . Fully professionalised units , such as the Telemark Battalion , serve as workhorse s in international operations . Sweden . The Grenadier Company is the honor guard of the Swedish Army Life Guards for state ceremonies . Their uniform includes bearskin hats , and white baldrics ( cross belts ) that originally carried the fuses used to light grenades . The grenadiers bear The King ' s own Life Company banner which was presented to the unit in 1868 by Karl XV ' s consort , Queen Louise . Switzerland . In the Swiss Army , the Grenadiers form well trained mechanised infantry units . They are used for especially challenging operations and are initially trained in Isone , a secluded , mountainous region in the South of Switzerland . The Swiss Grenadiers specialize in urban warfare , guerrilla warfare , anti - terrorist operations , commando tactics , sniper missions , hand to hand combat , and other special operations . United Kingdom . The Grenadier Guards are one of the five prestigious regiments of foot guards , all of which retain the bearskin headdress originally associated with grenadiers . The Grenadier Guards are officially recognized as the most senior regiment of foot guards , although this is not recognized by the Coldstream Guards , who are an older regiment founded six years earlier . The older age of the Coldstream Guards is not recognized as seniority because they were originally serving parliament , so the Grenadier Guards have a longer service to the crown . United States of America . A typical United States Army fireteam consists of four soldiers , with the designated grenadier being equipped with an M4 / M16 with the M203 grenade launcher ( or newer M320 grenade launcher ) slung under the barrel and providing limited high - angle fire over ' dead space ' . The United States Marine Corps fireteams include a team leader who also works as the M203 grenadier
