In recent years the threat of drones has become increasingly vivid to many security agencies. Drones, nowadays, are used by terrorist and criminals for a multitude and variety of activities such as dropping small bombs on enemy forces in Syria and Iraq, and the same drones are often used for reconnaissance and smuggling of illicit contrabands to prisons.

The Army has no standard-issue offensive jamming gear at all, although some is being developed and ad hoc kit is being hastily fielded to Europe. The Air Force has the EC-130H Compass Call, but it’s a big and slow target derived from the C-130 turboprop cargo plane, and the aircraft is wearing out.
