Well Jacko,
In these evolving times, it means watching all the bad guys all the time ie ISTAR (Intelligence, Surveillance, Target Acquisition & Reconnaissance) tasking which can be manned by a multitude of people and equipment (Watchkeeper UAV, covert street stuff, microphones in Hook prosthetics, that kind of thing).
Peeks at the Mil Forum on Pprune also qualify, or so I am led to believe
