TSA conducting nationwide security exercises with law enforcement/ military hardware

Why would TSA need a blackhawk helicopter to do a patdown?

'The exercise will cover approximately 5,000 square miles throughout Ohio, Kentucky and West Virginia. The participating teams are composed of a variety of TSA assets including federal air marshals, canine teams, inspectors and bomb appraisal officers. They will be joined by state and local law enforcement officials to supplement existing resources, provide detection and response capabilities. The exercise will utilize multiple airborne assets, including "Blackhawk helicopters" and fixed wing aircraft as well as waterborne and surface teams.'
