We need to set up Best Management Practices for shooting down enemy unmanned aerial vehicles. There are many reasons for this directive for instance; we must make sure what we are shooting is really an enemy UAV and not one of our own; that it is not a friendly force craft; that it is not a civilian aircraft which happened into our net-centric security grid or kill box.
Additionally an enemy UAV will generally have a mission, whether it is a single mission as a flying bomb or a surveillance mission and will return to base. If it is surveillance unmanned aerial vehicles then by the time you see it, it may have already recorded your assets and their locations and killing it serves no purpose as the cat it now out of the bag. However if we track and follow it via satellite, radar or other flying vehicle, we can learn a lot. Such as where did it come from and if you kill it straight away, then you will never know where it came from. If you follow it, you now have a very valuable target of your enemy
