A firing platform for the perimeter: a 2.1 m square deck 2.6 m up on four braced pine posts, decked in boards, screened waist high in steel sheet on three sides with a rail over it, reached by seven steps on the +Z face with a handrail, and with a sandbag laid on the rail as a rest. Dimensions 2.12 × 3.86 × 3.35 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.
