When hikers vanished in the glacier-carved valley, the tracked carrier rolled out within minutes. Equipped with infrared drones and a thermal imaging mast, the tracked carrier navigated scree fields that stopped wheeled trucks cold. Its low-ground-pressure belts distributed weight like a snowshoe, allowing the tracked carrier to cross thin shelf ice without cracking it. On arrival, the crew deployed a telescopic boom from the tracked carrier to lower rescuers into a 40-meter crevasse, retrieving two hypothermic climbers. Inside, the tracked carrier doubled as a mobile ICU, warming patients with onboard diesel heaters while medics stabilized fractures. A satellite uplink transmitted vital signs to the trauma center so surgeons could prep before touchdown. When fog rolled in, the tracked carrier activated LIDAR terrain mapping, guiding itself and a following snowcat safely back to base.
