Russia
The Russian military is divided into the Ground Forces, Navy, and Air Force. There are also three independent arms of service: Strategic Missile Troops, Aerospace Defence Forces, and the Airborne Troops. , the military comprised over 1 million active duty personnel, the fifth largest in the world. Additionally, there are over 2.5 million reservists, with the total number of reserve troops possibly being as high as 20 million. It is mandatory for all male citizens aged 18–27 to be drafted for a year of service in Armed Forces.
Imperial Russian Army
As part of Milyutin's reforms, on 1 January 1874, the Tsar approved a conscription statute that made military service compulsory for all 20-year-old males with the term reduced for land army to six years plus nine years in reserve. This conscription created a large pool of experienced military reservists who would be ready to mobilize in case of war. It also permitted the Russian Empire to maintain a smaller standing army in peacetime.
Ironically, this reform was a disaster for the Tsarist regime. By reducing the length of service, peasant elders and officials could no longer threaten radical youths with conscription. Soldiers now kept their peasant identities and many learned new skills and became literate. They radicalised the villages on their return.
