Cavalry is the weapon of soldiers or warriors who fight on horseback. It is the third oldest combat weapon (after infantry and warships) and the most mobile. From the earliest days of its use, the cavalry offers the advantage of mobility, which makes it a formidable instrument of war because it allows to overflow and avoid the opponent, to surprise and defeat, to retreat and to escape the enemy according to the needs of the moment. It is also the weapon of raids in the depth. The mount gives the rider several advantages over his opponent on foot: speed, height, mass and inertia during the shock. Another factor of superiority results from the psychological impact of the appearance of the soldier on horseback on the infantryman.
