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.
Conscription
Bulgaria had mandatory military service for males above 18 until conscription was ended in 2008. Due to a shortfall in the army of some 5500 soldiers, parts of the current ruling coalition have expressed their support for the return of mandatory military service, most notably Krasimir Karakachanov. Opposition towards this idea from the main coalition partner, GERB, has seen a compromise, where instead of mandatory military service, Bulgaria could possibly introduce a voluntary military service by 2019 where young citizens can volunteer for a period of 6 to 9 months, and will receive a basic wage.
