When road conditions are bad, having the supplies air-dropped can be critical. These supplies we used to support a village that had been cut off by heavy snows. While road conditions locally were passable, the roads through the mountain passes had been closed for nearly two months. Another thing the ETT does is assist with planning, supplying, and performing Humanitarian Assistance missions. The air-drops have to be planned, the drop zone identified, secured, and the goods collected and then distributed.
