Following the
Russo-Japanese War major attempts were made at military reform, including the extension of the conscription system to enlarge the pool of trained reservists. The conscription system as evolved during 1910–1914 set call-up liability at the age of 21 with a commitment for active and reserve service that lasted until 43. Service "with the colours" varied from three years for infantry and artillery, to four years for cavalry, engineers and support corps. The individual conscript would then pass into the "First Reserve" for seven years and the "Second Reserve" for eight years. As had been the case since the 18th century, the commitment for conscription fell primarily on subjects of Russian nationality.
Muslims and
Finns were exempted, although the former were required to pay a special tax and the latter were enlisted in a separate corps of Finnish regiments with no commitment to serve outside their homeland. About half of potential Russian conscripts were able to obtain exemption for a variety of personal reasons, although they might be required to serve with the
militia upon the general mobilization of the regular army. A continuing weakness in the Russian system was a shortage of long-service volunteers to provide career NCOs.
Cossacks served under a complex and semi-feudal conscription system of their own and "Alien" cavalry units were recruited as volunteers from Muslim tribal groups in the southern regions of the Russian Empire. ==See also==
