In August 2023, ICE/HSI’s counter-fentanyl and counter-fentanyl-related substance operations transitioned from Southwest Border surge efforts to a nationwide, counter-opioid initiative known as Operation Opioid Response and Investigation of Networks (ORION). Operation ORION aligns with the goals and strategies set forth in the Strategy for Combating Illicit Opioids, allowing HSI to leverage its vast administrative, civil, and criminal law enforcement authorities to counter fentanyl and fentanyl-related substance distribution. Under the operation, HSI continued to increase the number of Border Enforcement Security Task Forces (BESTs), Fentanyl Abatement and Suppression Teams, and Fentanyl Overdose Resolution Teams in strategic locations to support HSI’s nationwide fentanyl and fentanyl-related substance supply reduction strategy. This increase will simultaneously be reflected in HSI and CBP joint operations at and along the Southwest Border.
