The Sioux War Chief has a lot of hit points, very fast speed and no range, but deals Area of Effect damage. The War Chief will faint if his hit points reach 1. He has the Nature Friendship ability, and the ability to increase the speed of all units around him making him useful in raids on the enemy. He regenerates hit points when injured.

"War chiefs, typically young men in their prime, were responsible for leading warriors into battle. Even though they led their tribe's war efforts, they had to answer to a council of tribal leaders who attended to the daily affairs of the tribe.
One of the most renowned war chiefs was Sitting Bull (1831-1890), also known as Tatanka Yotanka. Born in the territory of present-day South Dakota, he was renowned as a Sioux medicine man and prophet. Sitting Bull led Native resistance against U.S. government attempts to take over tribal lands, which included his involvement in the Battle of the Little Bighorn with his lieutenants Crazy Horse and Gall. After spending several years in Canada with his followers, Sitting Bull returned to the U.S. under a government amnesty program."
