Anna Grimsdottir

Anna Grímsdóttir is the Fourth Echelon technical operations manager. Previously she was Communications Lead at Third Echelon. Her job was to provide Sam Fisher with technical support while he is in the field, addressing any high-technology issues that he encountered during operations. A skilled hacker, Grim fronted the remote intelligence retrieval operations that Third Echelon conducts prior to inserting field operatives, if required. She was also responsible for direct technical operations through Fisher's OPSAT (OPerational SATellite Uplink) connection to computer terminals in the field.

Anna Grímsdóttir was born in 1974 in Boston, Massachusetts. Being a second generation American, her mother immigrated to the U.S. alone from Akureyri, in northern Iceland. She had once mentioned to Fisher that while he was fighting overseas in 1989, she was in the tenth grade.

Grim dropped out of St. John's College in the mid-1990s and worked as a programmer in different private communications firms contracted by the U.S. Navy. She was recruited into the NSA in the late-1990s, and rose quickly in rank as the Internet became more and more important to national security. Grímsdóttir then moved on to Third Echelon, where she was put in charge of a small team of programmers responsible for providing technological, cryptographic and data support as part of the Splinter Cell program and assist field agents via their interface with the high-tech components of their missions.
