Color-wise this is a vivid, very dark brown leaning warm. Within the Green Stuff World range it ladders cleanly, Prussian Green for the shadows and Ranger Green for the highlights. Substitutes are thinner on the ground; P3 Paints Thornwood Green is the nearest same-finish option at 84 percent, with 1 brand in strong-match range. Any substitute is a mixing base rather than a drop-in, so tune it on the model.
Olive-Brown Ops equivalents and near misses
Fair warning: nothing matches Green Stuff World Olive-Brown Ops cleanly. The options below are the least bad, and every one of them drifts.
Closest P3 Paints equivalent: P3 Paints Thornwood Green, close, with a hint of drift side by side (delta E 3.2).
Revell's closest color: Revell Leather brown / Lederbraun (RAL 8027), workable at tabletop distance, not up close (delta E 4.4).
Nearest in the Vallejo catalog: Vallejo Cayman Green, a usable stand-in rather than a twin (delta E 4.7).
Best AK Interactive option: AK Interactive Reflective Green, workable at tabletop distance, not up close (delta E 4.8).
Worth knowing before you swap: P3 Paints Thornwood Green runs slightly cooler and more muted, which shows most where the paint thins over raised detail.
