JanissaryA Janissary (yeŋiçeri, jeniˈtʃeɾi, new soldier) was a member of the elite infantry units that formed the Ottoman Sultan's household troops and the first modern standing army in Europe. The corps was most likely established under sultan Orhan (1324–1362), during the Viziership of Alaeddin. Janissaries began as elite corps made up through the devşirme system of child levy enslavement, by which Christian Albanians, Bulgarians, Croats, Greeks, Romanians and Serbs were taken, levied, subjected to forced circumcision and conversion to Islam, and incorporated into the Ottoman army.
Russian EmpireThe Russian Empire, also known as Imperial Russia, was the final period of the Russian monarchy from its proclamation in November 1721, until its dissolution in late 1917. It consisted of most of northern Eurasia. The Empire succeeded the Tsardom of Russia following the Treaty of Nystad. The rise of the Russian Empire coincided with the decline of neighbouring rival powers: the Swedish Empire, the Polish–Lithuanian Commonwealth, Qajar Iran, the Ottoman Empire, and Qing China.
SniperA sniper is a military/paramilitary marksman who engages targets from positions of concealment or at distances exceeding the target's detection capabilities. Snipers generally have specialized training and are equipped with high-precision rifles and high-magnification optics, and often also serve as scouts/observers feeding tactical information back to their units or command headquarters.
SkirmisherSkirmishers are light infantry or light cavalry soldiers deployed as a vanguard, flank guard or rearguard to screen a tactical position or a larger body of friendly troops from enemy advances. They are usually deployed in a skirmish line, an irregular open formation that is much more spread out in depth and in breadth than a traditional line formation. Their purpose is to harass the enemy by engaging them in only light or sporadic combat to delay their movement, disrupt their attack, or weaken their morale.
InfantryInfantry is a military specialization of military personnel who engage in ground combat on foot. Infantry generally consists of light infantry, irregular infantry, heavy infantry, mountain infantry, motorized infantry, mechanized infantry, airborne infantry, air assault infantry, and naval infantry. In English, use of the term infantry began about the 1570s, describing soldiers who march and fight on foot.
French Foreign LegionThe French Foreign Legion (Légion étrangère) is a corps of the French Army that consists of several specialties: infantry, cavalry, engineers, airborne troops. It was created in 1831 to allow foreign nationals into the French Army. It formed part of the Armée d’Afrique, the French Army's units associated with France's colonial project in Africa, until the end of the Algerian war in 1962. Legionnaires are highly trained soldiers and the Legion is unique in that it is open to foreign recruits willing to serve in the French Armed Forces.
