The faction field guide.
Every faction in 40k carries its own arithmetic — its archetypes, its hard counters, the matchups that consistently break in or against it. Dossiers is the section that catalogs that, faction by faction. It does not republish aggregator win-rate tables; it indexes signals, names patterns, and links out to where the deeper data already lives.
The Strength Index tier list below is the cross-faction headline read. Per-faction dossier pages drill into one army at a time: archetype, per-target / per-threat radar, Unit Lab roster, concentration callout, editorial perspective, and tournament-recap cross-links.
A dossier is a description, not a verdict. The Strength Index reads four signals side by side without collapsing them; long-form essays live on Awakenings. Dossiers is the field guide between them.
