deployment of armed forces on an involuntary basis only in cases stipulated by law (). The deployment of military units composed of reservists, takes minimum time and does not requires any retraining of military personnel. The military units composed of reservists use the same weapons as used by military units, composed of active duty military personnel. Military units staffed by reservists are 100% manned up to wartime standards just like military units staffed by active duty military personnel only. There is no possibility to define by military units designation what we're dealing with - reserve or not reserve military unit. The number of reservists is not presented in open sources and is not among the number of active duty military volunteers which is published by Ministry of Defence. This makes it difficult for establish real troop strength of new Russian military units and formations. 2019 reform of the reserve officer training system In 2018 the military departments and the military training centers were abolished. From that moment on, students of civilian institutions of higher education were trained under both officers training programmes (for reserve and for active duty) in the Military Training Centers.

Budget Between 1991 and 1997 newly independent Russia's defence spending fell by a factor of eight in real prices. In 1998, when Russia experienced a severe financial crisis, its military expenditure in real terms reached its lowest point—barely one-quarter of the USSR's in 1991, and two-fifths of the level of 1992, the first year of Russia's independent existence. In the early 2000s, defence spending increased by at least a minimum of one-third year-on-year, leading to overall defence expenditure almost quadrupling over the past six years, and according to Finance Minister Alexei Kudrin, this rate is to be sustained through 2010. Official government military spending for 2005 was US$32.4 billion, though various sources, have estimated Russia's military expenditures to be considerably higher than the reported amount. Estimating Russian military expenditure is beset with difficulty; the annual IISS Military Balance has underscored the problem numerous times within its section on Russia. The IISS Military Balance comments, "By simple
