Choosing a unit emblem is quite a challenge for a commander's personal cultural cultivation and aesthetic taste. Some use flowers, birds, fish, and insects, and some use famous buildings where the troops are stationed, while others use ancestral unit emblems to signify historical heritage. However, the most common choice is a beast.
Using beasts or birds of prey as unit emblems is a wish for the troops to inherit the fierceness, cruelty, and agility of these animals. Eagles, wolves, wild boars, lions, tigers, bears, among others, are all emblems that make one immediately feel the word "ferocious", and putting these together resembles a sort of symposium at a zoo's predator hall.
