The Alaska State Trooper Special Emergency Reaction Team (SERT) responds to high-risk incidents, including hostage situations, barricaded individuals and high risk warrant executions. SERT Teams are located in the urban posts of Fairbanks, Palmer, and Soldotna. SERT is an additional voluntary assignment for specially-qualified Troopers, in addition to their regular duties. SERT Troopers train two days each month and remain on call after hours for emergencies.
