Here's all you need to know about SAS Operation Tango.

Operation Tango

Operation Tango was an SAS mission carried out in Bosnia on 10 July 1997.

Conducted under NATO’s Stabilisation Force, known as SFOR, it targeted two Bosnian Serb men indicted by the International Criminal Tribunal for the Former Yugoslavia for alleged war crimes committed during the Bosnian War.

The mission

Two separate five-man SAS teams were deployed by helicopter into the Prijedor region.

Their objective was to make simultaneous arrests, preventing either suspect from escaping if warned about the other’s detention.

The teams were equipped with arrest warrants issued by the tribunal and acted under NATO authority.

Milan Kovačević

One team targeted Milan Kovačević, the former mayor of Prijedor and then director of the local hospital.

According to accounts of the operation, SAS soldiers gained access to the hospital by posing as Red Cross officials.

Kovačević was arrested without resistance and transferred to NATO custody before being flown to The Hague to face trial.

Simo Drljača

The second team targeted Simo Drljača, a former police chief accused of helping orchestrate the ethnic cleansing of Bosnian Muslims in the Prijedor area.

The SAS located him while he was fishing at a reservoir.

During the attempted arrest, Drljača reportedly opened fire, wounding an SAS soldier in the leg. The SAS returned fire, killing him at the scene.

The outcome

Operation Tango was completed rapidly and was widely viewed as a success by NATO.

One suspect was arrested and transferred for prosecution, while the other was killed after resisting arrest.

The mission demonstrated NATO’s willingness to pursue indicted war criminals and paved the way for further detention operations in the Balkans.

Its significance

Operation Tango is considered one of the SAS’s most notable post-Cold War operations.

It helped establish a precedent for future international efforts to arrest people accused of war crimes and strengthened the authority of international tribunals operating in the former Yugoslavia.

The operation also enhanced the SAS reputation for precise, intelligence-led missions in politically sensitive environments.
