Nurse Kathy McCammon was a Starfleet crewperson during the Dominion War.
In 2374, a file from starship the USS Akagi reported McCammon missing in action. A file from the USS Zapata reported her killed. (DS9: "In the Pale Moonlight")
McCammon's name appeared on the casualty list display seen on a computer readout in that episode. It is unclear which of the above was her home station, if any.
