The army is divided into seven army-corps (ordus), each under the command of a field marshal, and the two independent commands of Tripoli (Africa) and the Hejaz.
The headquarters of the ordus are I., Constantinople; II., Adrianople; III., Salonica; IV., Erzerum; V., Damascus; VI., Bagdad; VII., Yemen; 15th division, Tripoli; 16th division, Hejaz.
The nizam cavalry is incorporated with the first six ordus, one cavalry division of 3 brigades of 2 regiments each being appointed to each ordu.
But the unequal strength of the ordus and political and other reasons have prevented this organization from being carried out.
Ordus, with headquarters at Erzinjan and Bagdad respectively, could be grouped as an army of the Caucasus in case of a Russian war, but were practically unavailable for Europe.
