The Special Events Response Team (SERT) consists of Troopers extensively trained in riot control formations and mobile field tactics. The New Hampshire State Police SERT was formed in the late part of 2003 for a variety of reasons. Consideration was given to increased terrorism activities and potential protests over on-going military conflicts. Also, the location of the 2004 Democratic National Convention in Boston increased the need for regional effectiveness in crowd control tactics.

The mission of the Special Events Response Team is to assist with large crowds or disturbances. These events include protests, large gatherings, prison alerts and large-scale searches in which manpower is needed to respond in a rapid manner. SERT is utilized during the annual Laconia Classic Motorcycle Rally, monitoring approximately 200,000 people, and during the NEXTEL NASCAR Races, monitoring approximately 100,000 people. The Team also assists statewide colleges with sporting event celebrations. The largest deployment in 2007 was for the Major League Baseball World Series, and efforts were concentrated in the towns of Durham, Keene and Plymouth.

SERT has trained with members of the County and State Correction Departments and is able to augment their units during prison disturbances. SERT plans to expand its training to be able to assist the Fish and Game Department or any agency with large scale searches. This added training will include land navigation and man-tracking skills.
