How deadly drone swarms will help US troops on the frontline

This is interesting reading and video on the use of drones. Watching the video and seeing the swarms of drones acting as a team, as wasps and bees might do, makes me wonder what other animal behaviors we might learn from and apply to modern warfare. Maybe someday we can graze contentedly as cows do, but as long as there are predators in the world, we need to look for unique defense strategies and tactics.
