Cavalry is the unit and arms that ride horses to perform tasks in the army. You can fight on horseback and on foot. Usually responsible for frontal assault, roundabout encirclement, pursuit, attack and other tasks. Its action is light and agile, and it is less affected by topography and meteorology. Historically, cavalry was once the main combat arm of the army.

The cavalry is an organized and fast force. They can attack their opponents quickly, or they can retreat quickly and leave the battlefield when the situation is unfavorable (unless they are also engaged in a fast and highly mobile force).

Cavalry is a group of soldiers who have been trained for a long time and can fight on horseback. Because of its high speed, cavalry usually undertakes reconnaissance tasks, or when the enemy has just formed an army and assembled, it carries out guerrilla work to beat and run and disturb the enemy. The U.S. military also refers to the troops and units that carry out reconnaissance missions by combat reconnaissance vehicles or helicopters as armored cavalry or air cavalry. With the wide application of modern science and technology and weapons and equipment in the battlefield, cavalry gradually lost its original status as an arms. Some countries only keep a small number of cavalry, mainly used for patrol, reconnaissance, vigilance and other tasks.
