About time they added some extended fiction characters! In case you don’t know, the woman Lasky addressed on the comm as Admiral Osman is a character in Karen Traviss’ Kilo-Five trilogy. She takes over as the head of ONI from Margaret Parangosky (whose name is mentioned in one of the briefing docs that came with the LE). Interestingly enough, Osman is an ex-Spartan-II that “washed out” of the program by not completing the augmentation process. The first two of Traviss’ books (Glasslands and The Thursday War) talk about how Parangosky is grooming Osman to take over for her. I’m assuming the unnamed third title will actually have Osman assume the throne, so to speak.
