Requests for HBT assistance come from the Sheriff’s Police, local suburban law enforcement and Federal
Members of HBT must successfully complete a certified Basic SWAT School before participating in Team activations. In addition to their regular assignments, members of HBT train together one complete week a year and 16 additional hours a month. They also receive approximately 100 hours a year in specialized outside training, in addition to the above. The Sheriff’s Police HBT is compliant with the National Tactical Officers’ Association’s standards.
HBT has participated in various national competitions over the last several years and have received numerous awards from outside agencies including the Illinois Tactical Officers Association and the Illinois Crime Commission.
