 In wartime, five military troops consisting of a central army, an advanced army, a left army and a right army were organized, according to military commands, by the general of the central army.It is said that the traditional Korean game of "Yut" is patterned after these five military structures.Generally, the succession system of the Supreme Dangun and the Vice-Dangun was determined by heredity, and sometimes the ruler could be succeeded by one of the "Ohga", suggesting that the sovereign's power was not absolute.
