Recruitment

The Ottoman Empire established a new recruitment law on 12 May 1914. This lowered the conscription age from 20 to 18, and abolished the "redif" or reserve system. Active duty lengths were set at two years for the infantry, three years for other branches of the Army and five years for the Navy. These measures remained largely theoretical during the war.

Traditional Ottoman forces depended on volunteers from the Muslim population of the empire. Additionally, several groups and individuals in the Ottoman society volunteered for active duty during the World War, the major examples being the " Mevlevi " and the "Kadiri".

There were also units formed by Caucasian and Rumelian Turks, who took part in the battles in Mesopotamia and Palestine. Among Ottoman forces, volunteers were not only from Turkic groups; there were also smaller numbers of Arab and Bedouin volunteers who fought in the campaign against the British to capture the Suez Canal, and in Mesopotamia. Volunteers were considered unreliable by the organised army, due to a lack of training and a perception of mainly mercenary interests from the Arab and Bedouin volunteers. Heavy fighting also placed pressure on the Ottoman volunteer system.
