Known as the “Queen of Battle,” the infantry is the branch of the army that provides its primary fighters. The main responsibility of infantry soldiers is to “close with and destroy the enemy.” Although they are trained, armed and equipped to fight onfoot, infantry soldiers are usually transported to the battlefield by other means. Infantry soldiers can also specialize as light, mechanized, airmobile, airborne and other types. The characteristics of infantry are mobility, firepower, flexibility,communications and vulnerability (to enemy action). Infantry soldiers are trained in a wide range of individual and crew-served weapons and work with the all-arms team of reconnaissance, armour, artillery, air defence, engineers, tactical aviation andother combat specialists. Except for a brief time during the feudal period (when cavalry dominated), the infantry has been the largest single component of armies since ancient times. In Canada, the infantry has always been thearmy’slargest element.

History of Infantry in Canada
The first infantry soldiers in Canada belonged to units of the regular French and British armies during the colonial period. Both the French and British colonial governments developed a system of calling out all fit civilian males between certain agesfor annual musters and, when required, for war. Eventually, citizens were grouped into the first infantry units, which were usually companies. Collectively, they were known as the militia. The militia was deployed at various times before and after Confederation,including theWar of 1812,1837 Rebellions in Upper Canada andLower Canada,Fenian Raids andNorth-West Rebellion.
Beginning in the 1800s, militia companies were grouped into battalions. In 1883, the Infantry School Corps was formed, becoming the first Regular Force infantry unit. It eventually became the basis for the Royal Canadian Regiment (RCR), Canada’s oldestRegular infantry unit.
TheSouth African War (Boer War) saw the first deployment of Canadian infantry abroad. This set the precedent for infantry contributions to theFirst andSecond World Wars,Korean War,Cold War,peacekeeping missions in several countries and peace support operations in theBalkans andAfghanistan.

Royal Canadian Infantry Corps
The Canadian Infantry Corps was authorized in 1942 and granted the “Royal” prefix in 1947. Today, the Royal Canadian Infantry Corps (RCIC) consists of three Regular Force regiments (all with three battalions), 49 Reserve regiments (all but two with onebattalion) and the Infantry School. There are also nine regiments on the Supplementary Order of Battle; these units have no members but can be reactivated if needed.
A key position in the RCIC is the Director of Infantry (D Inf), who is chosen by the Commander of theCanadian Army. D Inf is a secondary duty for a serving infantry colonel.In this position, he or she assists senior officers and non-commissioned members in the Army and Canadian Armed Forces in policy, force development, training, warfighting and other issues.

Regular Infantry Today
The Regular infantry battalions are grouped into three regiments: the Royal Canadian Regiment (RCR), Princess Patricia’s Canadian Light Infantry (PPCLI) and the Royal 22e Régiment (R22eR). The 1st and 2nd Battalions of each regiment are mechanized andequipped with the Light Armoured Vehicle 6.0. The 3rd Battalion in each regiment is a light infantry unit trained in various insertion methods (airborne, airmobile, amphibious) in a variety of complex terrains (urban, mountain, jungle).
The Regular regiments are assigned to three Canadian Mechanized Brigade Groups (CMBGs):
1 CMBG | 1st and 3rd Battalions PPCLI-CFB Edmonton, 2nd Battalion-CFB Shilo |
2 CMBG | 1st and 3rd Battalions RCR-CFB Petawawa, 2nd Battalion-CFB Gagetown |
5 CMBG | 1st and 3rd Battalions R22eR-CFB Valcartier, 2nd Battalion-Québec City |
Each infantry battalion is commanded by a lieutenant colonel and includes battalion headquarters, three rifle companies, a combat support company and an administrative company. Rifle companies are commanded by majors and consist of company headquartersand three rifle platoons (in a mechanized battalion) or two rifle platoons and a weapons platoon (in a light battalion). Each rifle platoon is commanded by a lieutenant or captain and includes headquarters, three rifle sections and a weapons detachment,each commanded by a sergeant. A weapons platoon has anti-armour and direct fire support sections. A combat support company provides all battalions with reconnaissance, signals and sniper capabilities, plus mortars, direct fire support and pioneers ina light battalion. An administrative company provides immediate battlefield maintenance, transport and supply.
Reserve Infantry Today
Reserve infantry regiments and their detached companies or platoons are found in nearly 100 cities and towns in every province, exceptPEI. Although they have the samecommand structure as Regular units, Reserve regiments have significantly fewer soldiers than Regular ones. Until recently, the role of the Reserves was to provide additional soldiers to regular regiments for domestic and overseas operations. In 2017,theArmy introduced Mission Tasks for Reserve units. In the infantry, certain regiments must now produce either a mortar, pioneer or direct fire support platoon. These platoonsbecome an integral component of a Regular Force unit when deployed.
