What's the difference between modern cavalry and ancient cavalry?

First of all, modern cavalry is a part of modern army, so it has all the characteristics of modern army.

The most important difference between the modern army and the ancient army is that the history of the modern army is maintained by nationalism and patriotism, and it is more cohesive and effective than the ancient army. Secondly, the modern army is a combat system, and its mobilization, management, training, combat, logistics supply and equipment are more systematic, standardized, scientific and refined, which is different from the extensive management of the ancient army. Modern cavalry is a part of modern army, and its mobilization and training, like other modern armies, is a complete system.

Secondly, the development of science and technology leads to great differences between modern cavalry weapons and equipment, tactical tactics and tactics and ancient cavalry.

Cold weapons are gradually replaced by hot weapons in the modern army, and the shields, bows and arrows and armor commonly used in the ancient army gradually disappear, while the guns and sabers used by cavalry become the main weapons of modern cavalry. Ancient cavalry, especially heavy cavalry, often served as the task of attacking the opposing army. In modern times, cavalry paid more attention to auxiliary tasks such as patrol, detection, harassment, encirclement and pursuit, and gradually handed over the impact on the embattled enemy to infantry and artillery.

It was not until the appearance of repetitive rifles replaced the early single-shot muskets that the combat troops on horseback gradually appeared to have no room for parry when facing infantry. The South African War from 1899 to 1902 was a farewell show of cavalry troops as the main force of the war. With the development of technology and equipment, especially the motorization and mechanization of the army, cavalry gradually lost its original position as an arms. At present, the armies of many countries only keep a small number of cavalry, which are mainly used for patrol, vigilance and transportation.
