The Iranian Embassy Siege: A Success with a Near-Failure
The 1980 Iranian Embassy siege in London stands as perhaps the SAS's most famous operation, but it nearly became a catastrophic failure. When six terrorists took 26 hostages and killed one, the SAS was called in after six days of failed negotiations. The rescue operation itself was successful, with five terrorists killed and one captured, but the planning and execution revealed serious vulnerabilities.
The SAS had only 17 minutes to plan the assault after months of inactivity. Several things went wrong: the assault team's explosives failed to breach one window, forcing an operator to smash through with a sledgehammer while under fire. Smoke grenades malfunctioned, and one terrorist nearly escaped through a balcony before being spotted. The operation succeeded despite these failures rather than because of perfect execution, demonstrating that even legendary units can have equipment failures and planning gaps under extreme pressure.
The Planning Nightmare
The Iranian Embassy operation exposed how the SAS had become complacent. The unit had been on standby for months without action, leading to rusty skills and outdated equipment. When the call finally came, operators had to raid a local hardware store for proper tools because their standard equipment wasn't suitable for the job. This operational failure in preparation nearly cost lives during the actual assault.
The Bravo Two Zero Patrol: A Complete Operational Failure
The 1991 Bravo Two Zero mission during the Gulf War represents one of the most significant SAS failures in modern history. Eight SAS soldiers were inserted behind Iraqi lines to gather intelligence and attack Scud missile sites. The mission went catastrophically wrong from the start.
The patrol was compromised within 24 hours when a goat herder discovered them. Rather than execute the herder as protocol suggested, the patrol commander decided to release him, hoping he wouldn't report their position. This decision proved fatal to the mission. Iraqi forces quickly located the SAS team, forcing them to attempt an escape across 200 miles of open desert.
The Escape and Casualties
What followed was a desperate fight for survival. Three soldiers died during the escape attempt, including the patrol commander. Four were captured and held as prisoners of war for weeks. Only one member, Chris Ryan, successfully escaped to Syria after an extraordinary journey of evasion. The mission failed in every conceivable way: intelligence gathering was non-existent, the target wasn't reached, and nearly the entire patrol was lost.
The Bravo Two Zero failure led to significant changes in SAS operational procedures, including improved communications equipment, better extraction plans, and revised rules of engagement for compromised patrols. The incident demonstrated that even elite units can make critical judgment errors with fatal consequences.
The Battle of Mirbat: Success Against Overwhelming Odds
While not a failure in the traditional sense, the 1972 Battle of Mirbat in Oman nearly became one of the SAS's greatest disasters. Nine SAS soldiers and approximately 40 Omani fighters defended a fort against 250-300 communist insurgents armed with AK-47s and RPGs.
The SAS soldiers were heavily outnumbered and outgunned. Their success depended entirely on the skill of their sniper, who held off waves of attackers while the defenders ran dangerously low on ammunition. The mission succeeded only because of extraordinary individual bravery and tactical improvisation rather than superior planning or equipment. Had the sniper been killed or his weapon jammed, the entire position would have fallen, resulting in a complete failure with likely total loss of life.
The Hidden Vulnerabilities
The Battle of Mirbat revealed how the SAS's success often depends on individual operators rather than systematic superiority. The unit's small size means that losing key personnel can instantly transform a successful mission into a catastrophic failure. This vulnerability remains a constant challenge for special operations forces worldwide.
The Northern Ireland Intelligence Failures
During the Troubles in Northern Ireland, the SAS conducted numerous operations against the Provisional IRA, with mixed results. While the unit achieved several high-profile successes, including the killing of eight IRA members in the Loughgall ambush, it also experienced significant intelligence failures.
In several instances, the SAS conducted raids based on faulty intelligence, resulting in innocent civilians being mistakenly targeted. The most notorious case involved the shooting of an innocent man in 1978, which led to public outcry and questions about the reliability of intelligence sources. These failures highlighted how even the best-trained soldiers can be compromised by poor information.
The Intelligence Problem
The Northern Ireland experience demonstrated that special forces are only as good as their intelligence. When information is incorrect or outdated, even the most skilled operators can find themselves in the wrong place at the wrong time. This fundamental vulnerability affects all military operations but is particularly acute for small, highly specialized units like the SAS.
Modern Operational Challenges
In recent years, the SAS has faced new types of mission failures related to changing warfare dynamics. Counter-terrorism operations in urban environments present unique challenges where civilian casualties or collateral damage can transform a tactical success into a strategic failure.
The 2017 London Bridge attack response highlighted these modern challenges. While armed police ultimately stopped the attackers, questions arose about why the SAS wasn't deployed more quickly. The incident revealed gaps in inter-agency coordination and response protocols that could have led to greater loss of life if the situation had escalated further.
Adaptation and Evolution
The SAS has continuously evolved to address its historical failures. Modern operations emphasize better intelligence gathering, improved communication systems, and more robust contingency planning. The unit has also developed stronger relationships with other agencies to ensure rapid response capabilities when needed.
Why the SAS's Failures Matter
Understanding the SAS's failures is crucial for several reasons. First, it humanizes an organization often portrayed as invincible in popular media. Second, it demonstrates that even the world's best special forces are not immune to operational setbacks, equipment failures, or human error.
Most importantly, these failures have driven continuous improvement in special operations tactics, equipment, and training. The lessons learned from each setback have made the SAS more effective over time, proving that failure, when properly analyzed and addressed, can lead to greater success.
Frequently Asked Questions
How often does the SAS fail missions?
Exact failure rates are classified, but the SAS maintains an exceptionally high success rate compared to conventional forces. Public records suggest successful outcomes in approximately 90% of known operations, though this figure excludes numerous classified missions where outcomes remain unknown.
What happens when an SAS mission fails?
Failed missions typically trigger immediate after-action reviews, equipment assessments, and procedural changes. Operators involved may face disciplinary action if negligence is determined, but most failures lead to systemic improvements rather than individual punishment.
Are SAS failures kept secret?
Many SAS failures are indeed classified to protect operational security and national interests. However, when failures involve significant casualties, diplomatic incidents, or public safety concerns, some information typically becomes public through official inquiries or investigative journalism.
How do SAS failures compare to other special forces?
The SAS's failure rate is generally comparable to other top-tier special operations units like the US Navy SEALs or Delta Force. All elite units face similar challenges with intelligence reliability, equipment performance, and the inherent unpredictability of combat situations.
The Bottom Line
The SAS has experienced mission failures throughout its history, from the near-disaster at the Iranian Embassy to the complete operational collapse of Bravo Two Zero. These failures, while relatively rare, have been crucial learning experiences that have shaped modern special operations doctrine.
What distinguishes the SAS is not an absence of failure, but rather its ability to learn from setbacks and continuously improve. The unit's willingness to adapt, innovate, and address its vulnerabilities has made it one of the world's most effective special forces despite occasional operational disappointments.
The real lesson from SAS failures is that perfection is impossible in warfare, but excellence is achievable through constant self-evaluation and adaptation. The SAS's willingness to acknowledge and learn from its mistakes, rather than hiding them, has been key to its enduring effectiveness over nearly eight decades of service.
