Military Mobilization — Russia & Ukraine Tracker
Russia launched its invasion with ~190,000 troops expecting a short war. After catastrophic early losses, Putin announced "partial mobilization" in September 2022 — Russia's first since World War II. Ukraine has maintained general mobilization since day one, expanding conscription laws in 2024 to sustain manpower amid enormous attrition on both sides.

Russia: September 21, 2022 "Partial Mobilization"
Putin signed Decree No. 647 on September 21, 2022. The official announcement cited 300,000 men with previous military service. However, the classified annex to the decree had no numerical cap, and Defense Minister Shoigu later confirmed up to 300,000 were called up. Human rights groups documented mobilization of men without military experience, disabled persons, and in some regions, young men with no prior service. Conscripts received as little as 2 weeks of training before deployment.
Mobilization Timeline
Full-scale invasion launched using ~190,000 pre-positioned troops. Russia expected short war with professional forces — no mobilization planned.
Initial invasion force
Ukraine announces general mobilization. President Zelensky signs mobilization decree. Men 18–60 banned from leaving country. Reservists called up.
Ukraine general mobilization begins
Russia suffers enormous losses in Kyiv, Kharkiv, Kherson. Attempts to refill units with contracted "volunteers" and convicts (Wagner Group). Denies need for mobilization.
Covert Russian manpower replacement
Putin announces "partial mobilization" — officially 300,000 men aged 18–65 with military experience called up. Actual decree had no upper limit on numbers. Mass exodus from Russia begins.
Russia's first mobilization since WWII
500,000+ Russians fled to Finland, Kazakhstan, Georgia, Armenia, Serbia within weeks of mobilization announcement. Estimated 700,000 left Russia by year end.
Mass emigration from Russia
Mobilized troops sent to front with minimal training (2–4 weeks). Many arrive without proper equipment. High casualties among recently mobilized units reported by Ukrainian intelligence.
Rapid deployment of poorly trained mobilized troops
Russia transitions to "crypto-mobilization" — recruiting via military commissariats, prisons, migrant workers (Central Asia), social pressure. Official mobilization not formally announced but continuous.
Sustained covert recruitment
Ukraine passes new mobilization law lowering draft age from 27 to 25. Tightens exemptions. Creates updated registry of eligible men. Controversial but necessary given manpower pressure.
Ukraine expands conscription pool
Russias recurring recruitment: $30,000–50,000 signing bonuses attract volunteers. Targets rural, economically disadvantaged, and ethnic minority regions. 25,000+ contracts per month estimated.
High-incentive contract recruitment
Ukraine faces significant manpower pressure. Political debate over lowering draft age to 18. Foreign legion and international volunteers provide supplemental force. Mobilization enforcement tightened in 2025.
Ongoing Ukrainian mobilization challenges
Russia sustains contract recruitment at ~30,000/month via regional bonuses exceeding 2 million rubles (~$22,000). North Korean troops (estimated 10,000–15,000) deployed to Kursk front — marking foreign troop integration into Russian operations.
Russia integrates North Korean troops
As of early 2026: Russia estimated at 600,000+ troops in/near Ukraine. Ukraine's armed forces estimated at 800,000–1,000,000 active personnel. Both sides sustaining high losses with no ceasefire reached. Russia's monthly contract recruitment offsetting ~25,000–35,000 monthly casualties.

Russia vs Ukraine: Force Comparison (2026 estimates)
| Category | 🇷🇺 Russia | 🇺🇦 Ukraine | Notes |
|---|---|---|---|
| Active military personnel | ~1,320,000 | ~800,000–1,000,000 | Russia total; Ukraine mobilized force incl. reserves |
| Deployed in/near Ukraine | ~470,000–530,000 | ~300,000–400,000 | Frontline and rear areas; UK MoD / Ukrainian GS |
| Monthly recruitment rate | ~25,000–30,000 | Classified (~15,000–20,000 est.) | Russia: contract bonuses; Ukraine: conscription |
| Cumulative casualties (KIA+WIA) | 450,000–700,000+ | 100,000–300,000+ (est.) | Wide estimate range; classified by both sides |
| Foreign fighters | ~15,000–30,000 (N. Korea, Wagner mercenaries) | ~20,000 (Int’l Legion, 52 countries) | North Korean troops confirmed from late 2024 |
| Reserve pool | ~2,000,000+ | ~1,000,000+ (mobilizable) | Theoretical; training and equipment are bottleneck |

Attrition Rate
UK MoD estimates Russia sustaining ~700–1,000 casualties (killed + wounded) per day in active fighting periods. This requires ~25,000–30,000 new troops monthly just to maintain strength — hence continuous recruitment.
Ukraine's Challenge
Ukraine faces a manpower squeeze: older experienced soldiers to replace, families resistant to drafting younger men, and political sensitivity around draft age. The 2024 law lowering age to 25 was deeply controversial.
Russian Ethnic Minorities
Analysis shows Russia disproportionately mobilized men from Buryatia, Dagestan, Tuva, and other minority regions. Casualty rates in these regions are significantly higher than ethnic-Russian regions.
International Legion
Ukraine's International Legion attracted ~20,000 foreign volunteers from 52 countries by 2023. The USA, UK, Georgia, Poland provided the most fighters. Provides valuable experienced personnel.
