Those who have served in the army know that a sergeant is a platoon commander. Of course, the orders are given by the comrade lieutenant, but all the responsible work to control the personnel and carry out the assigned tasks is carried out by the lower leadership, and specifically by the sergeant. Therefore, good sergeants in the army are worth their weight in gold, and no one normal commander will put anyone in this position. But where did this military rank come from? This issue and some others will be discussed in this military-patriotic post :).
Interestingly, in 11th century England, sergeants were called a special social stratum of landowners who kept their plots under the condition of performing a certain service to the king. It could be working in the royal chancellery or other administrative bodies, serving at the court, military service in the infantry, ... at times it reached the point of absurdity: serving a knife to the king at dinner or holding a basin for washing during the coronation.
In the 12th century in England, sergeants were also called officers who performed police functions. But in the regular army, the rank of sergeant first appeared in the 15th century in France, and then in the German and English armies. In the French army, this rank was awarded for a long time to servicemen who did not have the right to obtain an officer's patent, but who served as officers (analogous to a warrant officer in the Russian army).
In the Russian Empire, the rank of sergeant was introduced in the 17th century and existed in 1716-1798. Under Emperor Paul I, instead of the ranks of junior sergeant and sergeant, the ranks of junior non-commissioned officer and senior non-commissioned officer were introduced, respectively, which existed in Russia until 1917, and then existed in the White Army.
In the Soviet armed forces, the rank of sergeant was introduced by order of the People's Commissar of Defense of November 2, 1940. The non-commissioned officers were recruited from among the conscripts. The regular position of the sergeant is the commander of a squad, tank, combat vehicle.
But in the American army, sergeants are a caste of professional military personnel. They have advice from company sergeants, battalions, regiments, brigades, bases, divisions, commands, who decide whether a candidate is worthy of training as a sergeant or not. At the same time, instructor sergeants train not only soldiers, but also lieutenants in training units. Each American unit has its own sergeant major, who is the direct superior of all sergeants in that unit. And in July 1966, the sergeant position of adviser to the chief of staff of the United States was introduced in the United States.
