Joking apart, are these vehicles equiped to drop anything to someone lost or injured ?
If human resuers cant reach the the person promptly, it would seem that in some cases life could be preserved by dropping supplies.
Water, first aid kit, a blanket, matches, a two way radio, or if dangerous wildlife is in the area a firearm, could all save a life.

Or are the vehicles not suitably equiped for dropping anything.
If they can drop bombs for miltary purposes then they can drop anything else of similar size and weight. Or they only equiped for firing missiles.
