Each of the provinces of a kingdom possesses its own provincial army, under the control of the governor of the province. The ruler of a kingdom does not have direct control of the provincial armies of a province and must rely on the support of the appointed governor of the province in order to access a provincial army.
The exception is the Provincial Army of the Capital (首都州師, shutoshuushi), which is under the control of the kingdom's Saiho, who serves as the governor of the capital province. As a result, the army of the provincial capital is defaulted to the control of the monarch. The Provincial Army of the Capital possesses the same number of soldiers as the Forbidden Army, being around 37 500 soldiers, allowing the monarch of a kingdom to have direct access to double the number of military troops in times of conflict.
