NIPAS has been around for 15 years or so. The NIPAS Team consists of at least 1 police officer from each of the departments that have a contract with the team. If you do not have an officer that is on the team, you may pay to have access to the use of the team. The team is divided into several sub teams; IE: croud control, hostage, warrant, etc... Instead of every department having their own individual SWAT Team (which is more than expensive), each department can have one with little expense. Hope this helps to anyone that does not know about NIPAS
