The mission of CBP’s Special Operations Group (SOG) is to train, organize, equip, resource, and deploy tactical and emergency response personnel worldwide to protect America. Based in El Paso, Texas, SOG plans, coordinates, and executes national, regional, and international level operations. We reviewed the SOG program to determine its cost and effectiveness. We determined that CBP does not have formal performance measures for its SOG program and does not track SOG’s total program cost. The incomplete records of SOG and other components of CBP that support SOG limited the determination of the SOG program’s total cost. SOG program efficiency and effectiveness cannot be accurately determined without total program costs or formal performance measures. As a result, CBP may be missing opportunities to improve effectiveness and identify potential cost savings in the SOG program.
