Drones are vary rarely used for a couple of reasons. 1 its is only available to sgt+. 2. They are not the most stable platform, a lot of the time you put your drone out and it just disappears after giving it a command, or it just flies in circles for no reason. 3. If you are in thick brush/under trees the UAV thermals typically do not pick up your heat signature so it is possible to avoid detection.
