These drones seem to be all over our critical infrastructure and military bases. It doesn't take a rocket scientist to understand what they are doing. Who or what they are is not known yet. However, they are building up over all strategic targets and becoming more prevailant over the sky's around strategic infrastructure.  This build-up is in preparation for most likely a synchronized simutaneous attack to whipe out all electrical power and flood hydro dams initially and then quickly after attack all our military. Shock and awe!!
