O.S.7. is an elite unit operates throughout Chile, with sections in various regions, to investigate and dismantle criminal organizations involved in the illicit drug trade. Their responsibilities extend beyond drug seizures to include tackling associated crimes such as money laundering and arms trafficking.

O.S.7. agents often conduct their investigations in plain clothes to maintain a low profile and effectively gather intelligence. They work in close coordination with the Public Ministry of Chile (Fiscalía), carrying out investigations under the direction of public prosecutors.

Established to address the growing threat of drug trafficking, O.S.7. has become a critical component of Chile's national security apparatus. The unit is involved in a wide range of operations, from street-level drug dealing investigations to complex international trafficking cases. Their work includes intelligence gathering, undercover operations, and the execution of raids to apprehend suspects and seize illegal substances.

In addition to their law enforcement duties, O.S.7. also participates in drug prevention and awareness campaigns, working to educate the public about the dangers of narcotics. They are a highly specialized and respected unit within the Carabineros de Chile, playing a vital role in the nation's efforts to curb the influence of organized crime.
