Unfortunately the Ukrainian military is not the strongest country in terms of military, and definitely at a disadvantage in a Russian invasion.
Russian Nuclear Warheads: 6,257
Russian Military Funding: Approximately 62 billion USD or 56 billion EURO
Russian Military Personnel: Approximately 900,000 active
Military Strength: 2nd globally
Added Notes: Battle tanks outnumber Ukraine’s 3:1.
Ukrainian Nuclear Warheads: 0
Ukrainian Military Funding: Approximately 6 billion USD or 5.5 billion EURO
Ukrainian Military Personnel: Approximately 200,000 active
Military strength: 22nd globally
Added Notes: Weak aircraft and airstrike defense capability. However, most male adults in Ukraine have at least basic military training, and could come to service if need be. Arguably one of the hardest wars Russia would have had to fight in the region. Short-range air defenses and anti-tank capabilities are higher than would be expected, so can greatly slow Russian advancement into their territory.
