VIPR meaning in Governmental ?

A Visible Intermodal Prevention and Response team, sometimes Visible Intermodal Protection and Response (VIPR) is a Transportation Security Administration program. Various government sources have differing descriptions of VIPR's exact mission. It is specifically authorized by 6 U.S.C. § 1112 which says that the program is to "augment the security of any mode of transportation at any location within the United States". Authority for the program is under the Secretary of Homeland Security. The program falls under TSA's Office of Law Enforcement/Federal Air Marshal Service. TSA OLE/FAMS shares responsibility for the program with the Office of Security Operations and Transportation Sector Network Management.

The VIPR teams detain and search travelers at railroad stations, bus stations, ferries, car tunnels, ports, subways, truck weigh stations, rest areas, and special events. They also can deploy to deal with CBRNE/WMD (chemical, biological, radioactive, nuclear, and explosive weapons of mass destruction). They also inspect ships, containers, and vehicles.
