[@The Survivor] Put her down as Senior Inspector now. Deputy US Marshal refers to any marshal in a non-supervisory position, similar to the term Sheriff's Deputy being used to refer to law enforcement belonging to the Sheriff's Department who is not elected or appointed into the Sheriff position of a city or county. 1811 Criminal Investigator may be her rank in the Marshals Service, but she is still a Deputy Marshal until she earns the title of Supervisory Deputy US Marshal and any other title above it. Since Rosa is not in charge of three or more other US Marshals or clerks, she would've been promoted to Inspector/Senior Inspector sometime before being chosen for the operation.
