Who develops PSO security assignments?

The correct answer reflects the fact that the Federal Protective Service (FPS) is responsible for the development of security assignments within the context of PSO (Protective Security Officer) operations. FPS operates under the Department of Homeland Security and is tasked with ensuring the safety and security of federal facilities. As part of this responsibility, FPS develops policies and procedures that dictate how security measures should be applied, including the assignment of protective security officers to various tasks and locations.

In contrast, the other entities mentioned have different roles or responsibilities that do not encompass the development of security assignments. The contracting officer, for instance, focuses on contract management and oversight, while the PSO supervisor typically manages on-the-ground operations and personnel but does not have the authority to develop overarching security assignments. Lastly, the contract guard headquarters office may handle administrative functions but again is not tasked with developing security mission parameters or assignments. Thus, FPS is the appropriate body for this responsibility.
