Honestly curious. Has Navy rotary wing asserts ever been tasked with CSAR over the beach? Have they ever trained for it at Fallon or Red Flag?
Grenada was the last time the Navy did a CSAR though it was technically 'on the beach' instead of over it, it was an ad hoc rescue much like the entire operation. That mission and the entire history of CSAR are profiled in Leave No Man Behind: The Saga of Combat Search and Rescue, an excellent though lengthy book chronicling the history of US military CSAR from the very beginning to today.
