A sandbag emplacement: five courses of filled bags laid in a staggered bond, tapering from eight bags to six so the top course reads as a firing step, with a steel picket at each end and an ammunition can dropped behind it. Dimensions 4.07 × 1.30 × 0.91 m (X × Y × Z). Metre units, +Y up, +Z front; origin on the ground at the footprint centre unless stated. Damp conifer forest realism: wet concrete and corroded corrugated steel, weathered pine, dark bark and soil, deep needle green, olive canvas, gunmetal and machined steel, with five emissive colours (amber fire, white floodlight, green status, blue screen, red warning) that also form the loot rarity ladder. Static geometry; no rig, animation, collision or navigation data.
