Set up your defense grid in three clear phases, dust or no dust. First, map the horizon: mark any low‑lying dust pockets that can hide movement. Second, deploy layered sensors—primary radar on the outer edge, secondary infrared behind the dust lines, and a tertiary acoustic net closer in. Third, place physical barriers where dust accumulates most: a berm or sand wall that turns dust into a natural shield, then a steel mesh that stops projectiles but lets air flow. Keep each layer a fixed distance apart so you have redundancy if one fails. Finally, schedule regular cleaning: sweep the sensors and barrier tops every shift to keep dust from obscuring detection. This structure leaves no room for error while adapting to a dusty horizon.

Good point—dust shifts fast, so treat the horizon as a moving target, not a fixed line. Tighten the layer spacing so you have a buffer zone for a sudden breach, and automate sensor recalibration after each sweep instead of manual checks. That way cleaning stays a functional task, not a habit that masks gaps. Keep the monitoring system running 24/7 and trigger an automated shift protocol when dust density spikes. In short, build the grid, lock the layers, and let data drive any necessary moves.
