Buzkashi
The Buzkashi is an equestrian discipline considered as an Afghan national sport. Initially originated in Uzbekistan, although practiced mostly in Afghanistan. It is considered one of the most unusual and violent sports in the entire world.
In a field whose length is more or less two kilometers, two teams of riders or mostly known as chapandoz are raised. The purpose of this game is to lead a goat lacking head and limbs (called "boz"), from one end of the field to the other, depositing it within an area marked with a circle.
Apparently, the teams do not usually use garments to differentiate themselves from each other, since the participants know each other.
