“Welcome to the Armoury, ma'am. I'm the quartermaster Sergeant Katherine Green IV. If you need anything; weapons, ammo, equipment. Perhaps a change of clothing, I'm sure I have something around here for you. Or if you're just here looking for tasks to complete, you can take a look at the board over there, which has quite a few for you to complete. I'll even reward you for them too, ma'am. Oh, and here is some Credits. On me.”

―Katherine introducing the Armoury^[src]

Sergeant Katherine Green IV is a character introduced in Call of Duty: Retribution as the quartermaster of the Armoury, replacing Mr. Tachibana, whose status was unknown at the time. She is an Eclipse Army enlisted non-commissioned officer and is the fourth descendant of World War II veteran Allison Green, whom she bears near-identical resemblance to.

As a young girl, Katherine was extremely fascinated by the Eclipse Empire, specifically the speeches given by Anakin Jenkins Fall. She would sometimes act as if she was a member of the Eclipse Army, often role-playing with herself. Anakin J. Fall's influence on her was one of the few that ultimately made her join the Eclipse Army once she was 18, a prominent one being that her family, especially her mother's side, historically served in the military. She fondly remembers the stories told by her mother Katherine III.

Once she was accepted into the Army, she moved to Thunder Bay, Ontario where she trained at Fort Armstrong, an Eclipse Army base that operated in the region and was home to the 211th Regiment. It was here that she had met Sergeant Pyrrha Nikos who was later become a member of Arc Squad in 2046. She trained at the base for three months until she was evaluated to the rank of Corporal and began serving as a quartermaster for Fort Angel on Nirvana until she would be promoted to Sergeant and oversaw the Armoury located onboard Osnaburgh Station, a central command platform that orbits Earth and is visited by all branches of the Eclipse Military.
