The Zürich Security Forces, or ZSF, alternatively known as the Zürich Defense Force, is a private security force that appears in Call of Duty: Black Ops III.
Tasked with defending the city of Zürich from an influx of anti-technological terrorist attacks aimed at the controversial Coalescence Corporation, the Zürich Security Forces are reportedly a reputable force with a large amount of funding; they possess state-of-the-art drones, walkers, and GI Units. However, in-game they are portrayed as inefficient and inept in their handling of terrorist attacks, failing to stop Xavier Hirtzel and allowing the Coalescence Headquarters to be infiltrated by Jacob Hendricks.Alessandra "Outrider" Castillo is a member of the ZSF.
