Although security officers differ in many ways from military personnel, police officers, federal agents, and the like, the US and Australia have a growing proportion of security personnel that have former police or military experience, including personnel from senior management. Security guards are not required to make arrests, but have the authority to make a citizens arrest, or otherwise act as an agent of law enforcement, for example, at the request of a sheriff or police officer. Additionally, guards providing security services, which is a person who is paid to protect assets, property, or people, are sometimes regarded as fulfilling a private policing function.
