Provide personal protection and security to a person - usually a famous, wealthy, or politically important figure - from assault, kidnapping, assassination, stalking, loss of confidential information, embarrassment, accidents, terrorist attack, or other threats.
A security detail, often known as a PSD, standing for Protective Services Detail, Personal Security Detachment, or Personal Security Detail is a protective team assigned to protect the personal security of an individual or group. PSDs can be made up of military personnel, private security contractors, or law enforcement agents. In the U.S. Army, an individual's security team is called a Protective Services Detail. Typically the detail is composed of U.S. Army Criminal Investigation Command, Military Police, or other law enforcement personnel.
Today, PSD teams are often made up of private security personnel that are armed and traveling with clients in high-risk situations here in the United States and abroad. PSD teams can either by high-profile, where it is visible to would-be attackers that there is a security team, or PSD teams can be low-profile, where it is much more difficult for attackers to discover that there is a security team.
