Horse

A Horse is one of two extant subspecies of the odd-toed ungulate mammal species of Equus ferus. They are domesticated animals that function as steeds or as pulls for transports. Wild horses are known as Stallions. A notable breed of horse is the Andalusian.

Usage
The Boss kept an Andalusian during her time in Tselinoyarsk during the events of Operation Snake Eater. The FOX Agent Naked Snake encountered the horse shortly after his night-time infiltration into Dremuchij near the wreck. After Naked Snake was humiliated by The Boss via CQC, the horse proceeded to, while rearing, step on Snake's hand, injuring it. The andalusian proceeded to accompany The Boss up until her death at Rokovoj Bereg, where it briefly mourned for her before escaping from the bombing run she set earlier. The horse eventually found its way to a British horse market, where Strangelove found it. However, she wasn't able to actually verify if the horse belonged to The Boss due to it refusing to let her ride it, nearly killing her as well. She eventually discovered it was when the horse reacted to Snake, rechristened by that point Big Boss's presence a decade after Operation Snake Eater in Costa Rica while the latter infiltrated the AI lab. The horse accompanied Snake to the Mine Base, and later proceeded to give chase to Peace Walker, who was modeled after its former owner. However, it was critically injured from the fall from the Nicaraguan border, resulting in Big Boss shooting the horse to euthanize it.

In 1984, the Soviets utilized horses during their invasion of Afghanistan. Ocelot and Big Boss (the latter having recently awaken from a nine-year coma) utilized horses to arrive at the region of Afghanistan where Miller was being held, with their riding a brown and white horse respectively.

Behind the scenes
Horses first appeared in Metal Gear Solid 3: Snake Eater via The Boss's Horse, as well as in Metal Gear Solid: Peace Walker with the same character.

Horses as interactive characters later appear in Metal Gear Solid V: The Phantom Pain. In it, the player can call the horse over via whistling, as well as hide behind the horse while riding it in order to avoid detection by soldiers. If the player waits a while, the horse will occasionally defecate.
