  "question": "What is the probability of a military support or logistics soldier being killed or seriously wounded over five years in a Ukraine-scale conventional conflict?",
  "quick_answer": "There is no reliable per-capita casualty rate for support and logistics troops in a Ukraine-scale war. Older conflicts give only shares of total casualties, not individual rates, and long-range missiles and FPV drones have reshaped rear-area risk in ways historical figures cannot capture. Support roles are safer than the front line, but by a smaller margin than most people assume.\n",

  "perceived": {
    "description": "Civilians and prospective military personnel generally assume that support and logistics roles -- supply drivers, mechanics, communications specialists, medics, and rear-area administrators -- are substantially safer than front-line infantry. This intuition is broadly correct in conventional wars where rear areas are physically separate from the front. In a Ukraine-scale conflict, however, long-range artillery, ballistic missiles, and first-person-view (FPV) drones have increasingly penetrated rear areas, attacking logistics depots, training sites, command posts, and supply convoys at distances of 50-200 kilometers from the front line. No high-quality survey isolates public estimates of support-troop casualty rates, so the perceived side is editorial intuition.\n",
    "rough_estimate": "most people assume support troops face perhaps 1 in 10 to 1 in 20 the risk of frontline infantry; historical data from the 1982 Lebanon War suggests a smaller gap of roughly 2-3:1 for conventional wars, and Ukraine-era drone warfare may have narrowed it further",

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.\n",

  "caveats": "A reliable per-capita casualty rate for support and logistics personnel in a Ukraine-scale conflict cannot be extracted from currently available data. The available evidence establishes several facts that are not sufficient for a quantitative estimate: (1) historically, support troops in conventional wars have faced substantially lower per-capita casualty rates than frontline infantry; (2) the 1982 Lebanon War showed support units accounting for 16-21% of total casualties by branch, a smaller share than their estimated troop proportion; (3) FPV drones, long-range artillery, and ballistic missiles in the Ukraine conflict have specifically targeted logistics depots, supply convoys, fuel storage, and repair facilities at significant depth behind the front, eroding the traditional geographic protection that made support roles safer; (4) the total Ukrainian military casualty figures (46,000+ killed, 380,000+ wounded across roughly 1 million total personnel) are not disaggregated by role, making it impossible to isolate the support-troop rate from the overall force rate. The overall Ukrainian force killed+permanently wounded rate across all roles over three years is approximately 23-28% (using Zelenskyy's figures with 300,000 on the front and ~750,000 in support/rear roles), suggesting that even rear-area personnel face meaningfully elevated risk compared to peacetime, but the per-capita rate for support roles specifically remains unquantifiable from public data. This entry is flagged no_reliable_estimate because applying historical infantry-to-support ratios from the 1982 Lebanon War or WWII to the Ukraine drone-warfare context would launder a 40-year-old figure into a number that the underlying data cannot support.\n",
