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. According to further information from the Data Vault, the ZSF purchased Wraith aircraft from the Coalescence Corporation.
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.
Judging by the map Skyjacked, the ZSF apparently has a sub-division called the Drone Division. This division appears to operate a massive VTOL aircraft, which functions as a command and control centre for drones, such the Talon and the General Purpose Infantry Unit, which it can deploy. It also appears to have the facilities to utilize 3D printing technologies to print spare parts to repair the drones, as well as being able to repair the augmentations on cyborgs. The aircraft also possesses detention cells (which may also have some life-support capacity) for prisoners that appear to recede into the floor when not in use.
