"Law enforcement:
Red ball or redball, police slang for a high-profile case that draws media and political attention. Often used in the book Homicide: A Year on the Killing Streets and the television shows based on it, Homicide: Life on the Street and HBO's series The Wire.
In the science fiction film Minority Report, the names of future homicide victims and perpetrators are engraved on wooden balls. If a ball is red, it means that the crime will not be premeditated.
"Red Ball", first episode on the sixteenth season of the long-running crime drama television series Law & Order
Military:
Red ball is used by the Air Force, typically on the flight line, to identify supply or service requests that are needed urgently to avoid mission failure. Orders for supplies or services identified as "red ball" are given highest priority, taking precedent over other more routine maintenance and service work."
