Logistics officer was a position in the Romulan military.
Sublieutenant Setal was a logistics officer in 2366. When William T. Riker questioned Alidar Jarok (who was posing as Setal at the time) about the whereabouts and status of the Romulan fleet, he denied knowledge of it, something which Riker doubted, giving "Setal"'s position as his reason. "Setal" explained that he was only familiar with the sector he had been assigned to. (TNG: "The Defector")
