The Londonderry Police Department is a member of a regional special weapons and tactics team known as the Southern New Hampshire Special Operations Unit (SNHSOU). SNHSOU is responsible for responding to high risk incidents within the following member jurisdictions:
Londonderry currently has seven tactical officers and two negotiators on the team.
The SNHSOU consists of specially trained officers from each department to deal with high-risk or unusual incidents such as Active Shooter Response, Hostage Situations, Barricaded subjects that may injure themselves or others, and High Risk Warrant Service to name a few.
SNHSOU members are trained in special tactics to attempt to resolve incidents without harm to innocent persons, officers, and the suspects. The SNHSOU is made up of several components, which include a commander, team leaders, medics, snipers, negotiators, tactical officers, and a mental health clinician. The SNHSOU trains twice a month throughout southern New Hampshire. Members must pass a semi-annual firearms qualification and physical fitness test to remain on the team.
