The full paper is linked below. Classifier (7.0): Direct PPG-based blood pressure monitoring is substantively relevant to wearable physiological monitoring systems that could support heat-strain and fatigue detection in field operations, though the paper does not address military or occupational safety applications directly.

The full article is linked below. Classifier (8.0): A defence-industry account of soldier-worn wearable patches now being fielded to monitor heat strain, blast overpressure, chemical and biological exposure, and vital signs is directly relevant to the equipment militaries use to enhance safety, though adoption for the Singapore Army context requires local validation.

The full article is linked below. Classifier (7.0): An official US Army account of fielding a wearable platform that streams clinical-grade vital signs from soldiers to command posts, credited with catching a heat casualty during competition, shows concretely how militaries use wearables for safety, though applicability to Singapore Army procedures requires local validation.

The full article is linked below. Classifier (7.0): A wearable Army system that monitors gait and estimated core temperature to predict heat stroke before symptoms appear is highly relevant to safety in hot-weather training, which is central to Singapore Army operations, though local validation of thresholds and procedures is required.
