The intuition that military support and logistics roles are substantially safer than frontline infantry is directionally correct but less reliable than it once was. In the 1982 Lebanon War, a peer-reviewed military medicine analysis found support units accounted for 16-21% of total casualties while infantry accounted for 43-56%, a ratio of approximately 2-3:1 in favor of support troops. This distribution shows that support roles carried meaningfully lower risk than direct-combat roles in conventional warfare — but “lower” is not “negligible,” particularly in high-intensity conflicts.
The Ukraine conflict has introduced a specific complication: FPV drones, long-range precision rockets, and ballistic missiles with reported ranges of 50-200 kilometers have specifically targeted logistics depots, fuel dumps, railway hubs, repair facilities, and supply convoys throughout the conflict. The geographic assumption underlying the historical infantry-to-support differential — that rear-area personnel are physically separated from the battlefield — has been partially eroded. Ukraine’s own National Security and Defense Council reported in January 2026 that drone strikes account for roughly 60% of all Russian battlefield losses — further evidence that no rear-area role is as geographically insulated from precision weapons as the historical infantry-to-support ratios assume. Whether this has fundamentally shifted per-capita support casualty rates to match frontline rates, or has merely nudged them upward, cannot be determined from currently available disaggregated casualty data.
No reliable per-capita casualty rate for support and logistics roles in the Ukraine conflict is publicly available. Ukrainian casualty data is classified as a state secret and is not disaggregated by military occupational specialty. Applying 1982 Lebanon War or WWII-era infantry-to-support ratios to the current conflict would produce a number without meaningful empirical grounding in modern drone warfare conditions. The honest conclusion is that support-role risk in a Ukraine-scale conflict is: substantially lower than frontline infantry, materially higher than the near-zero conventional assumptions, and not currently quantifiable from public data with sufficient precision to report as a single probability.

Não existe um número confiável para a probabilidade de um soldado de logística ou apoio ser morto ou gravemente ferido numa guerra à escala da Ucrânia. Drones e armas de ataque profundo corroeram a antiga segurança da retaguarda, mas não se publicam dados que separem os papéis de apoio dos de combate.

Review of Military Casualties in Modern Conflicts -- The Re-emergence of Casualties From Armored Warfare- Estatística
In the 1982 Lebanon War, support units accounted for 21.1% of casualties in urban combat and 16.6% in non-urban combat, compared to infantry at 56% and 43% respectively.- Trecho
“"In the 1982 Lebanon War, infantry suffered the highest fraction of battlefield injuries in both urban and non-urban combat, at 56% and 43% respectively, followed by armor divisions at 17.1% and 34.8%, and support units at 21.1% and 16.6%." ”

- This study provides share-of-total-casualties data by role category, not per-capita rates. The support-unit share (16-21%) relative to infantry share (43-56%) shows that support troops were somewhat less likely to be casualties, but the ratio is much less favorable than civilian intuition would suggest. The paper cannot be used to derive a per-capita support-troop rate for Ukraine because: (a) the 1982 Lebanon War used different doctrine and technology, (b) the troop mix was different, and (c) the rise of long-range precision weapons and FPV drones in Ukraine has specifically targeted logistics and support infrastructure. This source establishes the historical baseline but does not provide a reliable modern estimate.

[2] Wikipedia (citing military doctrine and historical analysis) — Tooth-to-tail ratio
Tooth-to-tail ratio- Estatística
In the 2005 Iraq deployment, combat troops comprised only 11% of personnel (a tooth-to-tail ratio of 1:8.1), down from 19% in WWII (1:4.3) -- the large majority of a modern force is logistics and support.- Trecho
“"The tooth-to-tail ratio (T3R), in military jargon, is the number of military personnel it takes to supply and support ('tail') each combat soldier ('tooth'). [...] WW2: 19% combat proportion, ratio 1 : 4.3 [...] Iraq 2005: 11% combat proportion, ratio 1 : 8.1." ”

- The tooth-to-tail ratio documents the relative size of support versus combat forces but does not provide per-capita casualty rates for support troops in high-intensity peer-on-peer warfare. Ukraine is understood to operate with a much lower tooth-to-tail ratio than the modern US military (Ukraine's acute manpower shortage has pushed more personnel toward direct combat roles), making US-derived support/combat troop ratios even less applicable to the Ukraine context. Cited as structural context, not as a basis for a numeric estimate.

- Cited as evidence that long-range and FPV drone strikes have become the dominant casualty mechanism in the conflict, supporting the body's point that rear-area and logistics targets are no longer geographically insulated the way historical infantry-to-support ratios assume. This is a Russian-side casualty-attribution figure (Ukrainian casualty data broken down by role or mechanism is not published), used as the best available public evidence for the general trend; it is not used to derive a per-capita support-troop rate, which this entry flags as unquantifiable from public data.
