What's with the ancient cavalry riding three times ... can you see it when you are on the road ... where is the girl when you sprint ... I know this is to keep mobility.

There is a division of labor for one person to ride three times. One ride is the trench, which carries armor, weapons and materials. One ride is a riding horse, which can also be used as a backup war horse as a means of transportation, and the other ride is a war horse. Usually, it is only rotated with horseback riding for a short time to restore physical strength, but it will not be used for a long time to maintain combat effectiveness. In wartime, only war horses were used to charge. Besides, the army is organized. When cavalry charge on the battlefield, there is someone to take care of the rotating horses and chariots, which is called "horse pile" If there is no special horse stake, then the cavalry will take turns to go into battle and will not let the three horses go to the battlefield together. As for whether you can see it when marching, first of all, it is not a problem for professional cavalry to ride three horses without assistance, what's more, the army will hire civilian workers to look after the horses, and the cavalry with higher status will have their own attendants.
