現代の通常戦争における前線歩兵の死傷率について、世間の推定は思い浮かべる紛争によって大きく異なる。比較的低い9月11日以降の米国の戦争の死傷率(派遣者あたり、20年間で約270分の1)を基準にする人は、ウクライナ規模の対等国同士の紛争のリスクを大幅に過小評価することになる。第二次世界大戦のイメージを基準にする人は過大評価するかもしれない。現行世代の高強度通常戦争における前線歩兵の死亡または恒久的負傷の率を推定するよう世間に具体的に尋ねた質の高い調査は存在せず、体感側は編集上の直感である。
概算: 推定は約20分の1(9月11日以降の米国の戦争を基準)から約2分の1(第二次世界大戦の東部戦線を基準)まで大きく幅がある。実際のウクライナ規模の5年間の前線での率は、1.25分の1から2分の1の範囲にある可能性が高い

ウクライナ軍の戦死者約46,000人 + 恒久的・重度負傷者約190,000人 = 重大死傷者約236,000人(推定約300,000人規模の前線部隊、約3年間:2022年2月〜2025年2月)

死傷データの二つの構成要素を合算している。すなわち戦死者と、恒久的・重度の負傷者(任務に復帰しなかった者)である。ウクライナのゼレンスキー大統領は2025年2月、ウクライナ軍人46,000人超が戦死し、約380,000人が負傷したこと、そして負傷者のおよそ50%が回復して現役任務に復帰したことを確認した。これは、約190,000人の兵士が現役から外れるほどの重傷を負ったことを意味する。戦死者と恒久的な戦闘不能者の合計は約46,000 + 約190,000 = 約236,000人(約3年間)。分母はウクライナの前線部隊の推定規模である。ワルシャワの東方研究センター(OSW)は2024年に、ウクライナの総軍人1百万人超のうち、常時前線に展開しているのは約300,000人以下だと推定した。これにより、前線の役割で継続的に勤務する者の3年間の重大死傷率は 236,000 / 300,000 = 0.787 となる。5年間に投影するため、年間の重大死傷率を (236,000 / 3) / 300,000 = 0.2622(年間)とモデル化する。複利計算では、五年間の確率 = 1 - (1 - 0.2622)^5 = 1 - (0.7378)^5 = 1 - 0.218 = 0.782。上昇傾向(2025年の死傷強度は2023年より高かった)を考慮して0.80に丸めている。The Economistのより高い推定である戦死者約100,000人(2024年11月)を用い、負傷者に同じ50%の任務復帰率を適用すると、戦死者約100,000人 + 恒久的負傷者約200,000人 = 300,000 / 300,000 = 3年間で1.0となり、複利式で5年間に外挿すると0.87となる。不確実性の範囲は、より低いゼレンスキー公式数値と、より高い独立推定の両方を反映している。これは一般人口の生涯リスクではなく、特定の高リスク軍事職における職歴期間の確率を測るため、scopeはsubgroup_lifetimeである。重要な点として、前線部隊はローテーションするため、兵士が通常、五年間すべてを継続的な前線接触の中で過ごすわけではない。この5年間の数字は、前線ローテーションを含む職歴にわたる累積確率を表している。
注意事項: 見出しの80%という数字は、ウクライナ規模の紛争で五年間、前線の歩兵または機甲の役割に継続的に就く者にとっての最良推定であり、すべての軍務の役割に一般化すべきで…
見出しの80%という数字は、ウクライナ規模の紛争で五年間、前線の歩兵または機甲の役割に継続的に就く者にとっての最良推定であり、すべての軍務の役割に一般化すべきではない。「前線」と「支援」の区別は決定的に重要である。支援、兵站、事務要員の死傷率は大幅に低い(別項目を参照)。負傷者の50%という任務復帰率はゼレンスキーの発言から直接取ったもので、ウクライナ軍全体の平均を表す。前線歩兵に限った実際の復帰率(最も重い傷を負う層)はより低い可能性がある。ウクライナの死傷データは国家機密として扱われており、独立に検証された数値は入手できず、すべての推定に大きな不確実性が伴う。複利確率モデルは年間死傷率が一定と仮定しており、これは高強度期(2022年初頭、2024年末〜2025年)のリスクを過小に、強度の低い期間のリスクを過大に見積もる。死傷リスクは部隊の種類、前線の区域、装備、紛争の年によっても大きく異なる。

In a Ukraine-scale conventional conflict — where two peer militaries contest territory with artillery, armor, drones, and infantry — the cumulative probability of a front-line infantry soldier being killed or permanently incapacitated over five years is approximately four in five. This figure is derived from Ukrainian official casualty data (46,000+ killed, 380,000+ wounded over roughly three years, with ~50% of wounded returning to duty per Zelenskyy’s own February 2025 statement) combined with the Centre for Eastern Studies estimate that approximately 300,000 of Ukraine’s 1 million+ military personnel served directly on the battlefront. Against that frontline subgroup, the combined killed and permanently-seriously-wounded total of approximately 236,000 over three years yields a three-year casualty rate of about 79%, compounding to roughly 80% over five years on the assumption that casualty intensity remains at roughly its 2023-2025 average.
The perception gap here is not primarily civilian-versus-reality — most civilians know intuitively that frontline infantry service is dangerous. The gap is about the specific quantitative scale. People accustomed to the casualty rates of the post-9/11 US wars (roughly 1 in 270 per deployer over the entire 20-year OEF/OIF period) dramatically underestimate what a peer-on-peer high-intensity conflict looks like. The 2022-2025 Ukraine conflict is not merely somewhat deadlier than that baseline but on an entirely different scale: a three-year killed toll of roughly 15-33% of the frontline force (46,000 to 100,000 killed against an estimated 300,000-person frontline, per the sources above) dwarfs the 1-in-270 career risk reported for post-9/11 deployers. Independent estimates from The Economist and CSIS place the killed range at 60,000-140,000 over three years, which, if accurate, would put the five-year serious casualty rate even higher than the 80% point estimate.
Several caveats constrain this figure. First, “frontline” is not a permanent state: soldiers rotate between front-line positions and rear areas, and the 80% figure estimates cumulative lifetime exposure across a military career that includes both, not a scenario where someone stands in a trench for five uninterrupted years. Second, casualty intensity varied enormously across the conflict’s three years: early 2022 and late 2024-2025 were notably higher-intensity than mid-2023. Third, the killed-to-seriously-wounded ratio appears to have shifted over the course of the conflict as drone warfare became dominant; Ukraine’s own National Security and Defense Council reported in January 2026 that FPV drones account for roughly 60% of Russian casualties, and the shift toward drone-caused wounds (fragmentation, blast) versus gunshot wounds changes the medical outcome distribution. None of these caveats change the order of magnitude: frontline infantry in a Ukraine-scale conflict faces a roughly 80% probability of being killed or permanently incapacitated over a five-year exposure period.

“"In December 2024, Ukrainian President Volodymyr Zelensky said 43,000 Ukrainian soldiers had been killed and 370,000 injured since February 2022; he also said 198,000 Russian soldiers had been killed and 550,000 injured.

- Britannica records Zelensky's December 2024 official figures: 43,000 Ukrainian soldiers killed and 370,000 injured since February 2022. These are the official Ukrainian government line and likely represent a lower bound on actual casualties; independent estimates (see The Economist / CSIS source) run higher. The mid-February 2025 update to over 46,000 killed / 380,000 wounded and the "approximately 50%" return-to-duty rate for the wounded -- which the casualty arithmetic in this entry uses -- are carried by the Casualties of the Russo-Ukrainian War source, not by Britannica, which only reports the December 2024 numbers.

President Zelenskyy stated 43,000 Ukrainian soldiers killed / 370,000 wounded with 'approximately 50%' of the wounded returned to active duty, updating the toll in mid-February 2025 to over 46,000 killed and 380,000 wounded; The Economist estimated 60,000-100,000 killed and ~400,000 wounded in November 2024; CSIS January 2026 estimated 100,000-140,000 fatalities.- 抜粋
“"Subsequently, President Zelenskyy announced 43,000 Ukrainian soldiers were killed and 370,000 were wounded, but that 'approximately 50%' of these soldiers recovered and had returned to active duty. He updated the Ukrainian military's casualty toll in mid-February 2025, to over 46,000 killed and 380,000 wounded. The Economist estimated Ukrainian losses at between 60,000 and 100,000 killed and 400,000 wounded in late November 2024. [...] CSIS's January 2026 estimate: 500,000 to 600,000 Ukrainian military casualties, including killed, wounded and missing, and between 100,000 and 140,000 fatalities." ”

- Carries Zelenskyy's mid-February 2025 official figures (over 46,000 killed, 380,000 wounded) and his "approximately 50%" return-to-duty rate for the wounded -- the inputs to this entry's lower-bound serious-casualty arithmetic (46,000 killed + ~190,000 permanently wounded = ~236,000). Also provides the upper-bound casualty range for the uncertainty calculation: The Economist high end of 100,000 killed, combined with 400,000 wounded × 50% return rate = 200,000 permanently wounded, gives a 3-year total of 300,000 serious casualties against 300,000 frontline troops. The CSIS estimate of 100,000-140,000 fatalities is consistent with The Economist's range and underpins the high end of the uncertainty bound.

- 計算過程
- Provides the denominator for the frontline-specific rate calculation. The OSW figure of ~300,000 troops directly on the battlefront (out of ~1,050,000 total) is used as the frontline subgroup denominator. This distinguishes between the overall Ukrainian military casualty rate (~22-28% killed+permanently wounded across all 1M+ personnel) and the concentrated rate for the frontline-only subgroup (~79% killed+permanently wounded over 3 years when casualties are attributed primarily to frontline forces).

- Cited as evidence that drone warfare has become the dominant casualty mechanism in the conflict, supporting the caveat that the killed-to-seriously-wounded ratio has shifted as FPV-drone strikes replace a larger share of gunshot and artillery wounds. This is a Russian-side casualty-attribution figure (Ukrainian casualty data broken down by mechanism is not published), used as the best available public evidence for the general drone-warfare trend; it does not feed into the native/normalized killed-plus-wounded arithmetic above, which rests solely on the Zelenskyy/OSW/Economist/CSIS figures.
