Origins of the SAS: How a Desert Rebellion Shaped Modern Warfare
The SAS wasn’t born in a boardroom. It emerged from the dust of North Africa in 1941, a brainchild of David Stirling—a renegade officer with zero interest in conventional tactics. His idea? Small teams behind enemy lines, sabotaging aircraft, ambushing supply convoys, vanishing before retaliation. At first, High Command laughed. Then they watched Axis airfields burn. By 1942, the SAS was dismantling Rommel’s supply chain one fuel drum at a time. They operated in groups of four or five, traveling in modified Jeeps across 600-mile stretches of desert. Imagine that: 15 days without resupply, navigating by stars, surviving sandstorms that could flay skin.
That legacy matters. It established a doctrine: minimal footprint, maximum disruption. And that’s still their DNA. But here’s the thing—other units learned from them. The French Commandos Marine, the Israeli Sayeret Matkal, even the American Delta Force—they all studied SAS raids. So the question isn’t just who’s best now, but who evolved fastest. Because tactics age. Adaptability doesn’t.
The Selection Gauntlet: What the Public Never Sees
Only about 10% of candidates pass. That figure includes experienced infantry soldiers, many with combat tours already under their belts. The selection isn’t just physical—it’s psychological attrition. You’re deprived of sleep for days. Forced to navigate 40-mile mountain marches with a 50-pound pack in the Brecon Beacons, where hypothermia kills more than exhaustion. Temperatures can drop to -10°C. Rain turns trails into rivers. One year, three candidates died within 14 months. Training was suspended. But it resumed. Because the SAS believes you can’t simulate stress—you have to live it.
And that’s exactly where people don’t think about this enough: selection isn’t about finding the strongest. It’s about finding those who keep moving when every signal screams to stop. I find this overrated when it comes to brute strength. A 5'6" signals operator who can read terrain like a mapmaker has more value than a rugby player who quits at mile 20. Mental resilience is non-negotiable. But is it enough to claim global supremacy?
Operational Secrecy: Success Measured in Silence
You won’t find stats on confirmed kills or missions completed. The UK government doesn’t publish that. We rely on leaks, memoirs, and the odd parliamentary nod. In 1980, the Iranian Embassy siege in London changed everything. For 17 minutes, the world watched black-clad figures rappel down walls, breach doors, neutralize gunmen. Five terrorists dead. One hostage wounded. It was surgical. And it became the blueprint. Yet even that operation—iconic as it was—wasn’t their first. Or their most dangerous.
More recent actions remain classified. We know they were embedded in Iraq and Afghanistan, training local forces, conducting high-value takedowns. One unconfirmed report from 2015 suggests an SAS team extracted a British hostage from an ISIS compound in Mosul—400 miles behind enemy lines, using civilian vehicles and forged IDs. No air support. No extraction plan beyond walking out. If true, that’s beyond impressive. But absence of proof isn’t proof of absence. And that’s the paradox: the better they are, the less we know.
Comparing the Elite: SAS vs Delta Force vs Spetsnaz
Let’s be clear about this—comparing special forces is like ranking chess grandmasters by their opening moves. You don’t see the endgame. The Americans have more tech. The Russians have more manpower. The Israelis have more实战—real-world conflict every decade. The SAS? They have tradition. And discretion. But does that translate to superiority?
Delta Force: Bigger Budget, Broader Reach
Officially known as 1st SFOD-D, Delta is the US counterpart. They were founded in 1977—decades after the SAS—specifically to replicate their success. Budget? Estimated at $80 million annually. That buys advanced drones, biometric scanners, satellite comms. They led the raid that killed Osama bin Laden in 2011. High-risk? Absolutely. But they had real-time intelligence, stealth helicopters, and a 500-man support network. The SAS rarely operates with that level of overhead. Is that a weakness? Or a point of pride? Because sometimes, fewer resources force better thinking.
Spetsnaz: Quantity, Brutality, and Soviet-Era Ruthlessness
Russia’s GRU Spetsnaz units operate differently. Less finesse, more pressure. They’re trained in extreme cold, urban warfare, and sabotage on a massive scale. During the Chechen wars, they used "filtration tactics"—clearing entire city blocks, house by house, with minimal regard for collateral. It’s effective. It’s also controversial. Their strength? Numbers. They have over 20,000 operatives across multiple brigades. The SAS has fewer than 300 in active combat roles. But size isn’t skill. And that’s where the comparison gets muddy. Spetsnaz dominance in raw force doesn’t mean superiority in precision.
Sayeret Matkal: Israel’s Shadow Sword
They’re smaller than both. Roughly 200 operators. But their operational tempo? Insane. They’ve conducted cross-border raids into Syria, Lebanon, and even Sudan. In 1976, Operation Entebbe—rescuing 102 hostages from a hijacked plane in Uganda—was their masterpiece. 90 commandos flew 2,500 miles, landed at night, stormed the terminal in 90 seconds. One hostage and all hijackers dead. It was flawless. And their training? Even tougher than the SAS. Israeli conscripts are screened from age 18. Only 5% of volunteers pass. They emphasize improvisation. No two missions are alike.
What "Best" Really Means in Special Operations
Here’s the truth: there’s no universal metric. Is it kill count? Survival rate? Mission success percentage? We don’t have the data. The problem is, "best" is subjective. The SAS excels in long-range reconnaissance, hostage rescue, and covert infiltration. But they’re not the go-to for large-scale urban combat. That’s where others shine. And because missions are classified, we’re judging based on fragments—like trying to assess a painter by a single brushstroke.
Take endurance. The SAS Mountain Leader course requires candidates to survive alone in the wild for 72 hours with minimal gear. That changes everything when you’re behind enemy lines with no backup. But Delta Force focuses more on joint operations with drones and AI-assisted targeting. So who’s better? Depends on the battlefield. In Afghanistan’s mountains? SAS. In Baghdad’s suburbs? Maybe Delta.
Frequently Asked Questions
How long does SAS selection take?
Officially, it lasts four weeks—but that’s just the field phase. The entire process, including pre-selection fitness tests and medical screenings, can stretch over six months. Candidates must complete a 64-kilometer (40-mile) march across the Brecon Beacons within 20 hours, carrying 25 kilograms (55 pounds). Many fail not from weakness, but from navigation errors. One wrong turn, and you’re disqualified.
Can foreigners join the SAS?
Technically, no. You must be a British citizen and have served at least three years in the UK armed forces. Exceptions are rare. There was one confirmed case in the 1990s—a New Zealander who became a UK citizen first. But even then, he served five years in the Royal Marines before applying. Citizenship isn’t enough. You need institutional trust.
Have SAS operatives ever been captured?
Very few. But it has happened. During the Gulf War in 1991, an eight-man patrol codenamed Bravo Two Zero was dropped behind Iraqi lines. Three died. Four were captured and tortured. The sole survivor, Chris Ryan, walked 300 kilometers to Syria—still holding the record for the longest escape and evasion in SAS history. The mission was a disaster. And that’s a reminder: even the best fail.
The Bottom Line: Is the SAS the Best?
I am convinced that they’re among the top three. But claiming they’re the absolute best? We’re far from it. The thing is, excellence isn’t static. The French have quietly built a counter-terrorism unit—GIGN—that has a 95% hostage survival rate. The Australians have the SASR, which matches British SAS in jungle warfare. And that’s the irony: the SAS pioneered modern special forces, but the world caught up. Some might say, even surpassed them in niche areas.
My personal recommendation? Stop chasing the "best" label. Focus instead on fit. The SAS thrives in environments where stealth and autonomy matter. If you need a team to disappear for weeks and reappear inside a terrorist compound, they’re your pick. But if you need overwhelming force or electronic warfare integration, look elsewhere.
Honestly, it is unclear whether any single unit holds a permanent edge. The battlefield evolves. So must the warriors. The SAS remains a benchmark. A legend. But legends don’t win wars. Operators do. And in that shadowy world, reputation means less than results. SAS operators are exceptional, no doubt. But exceptional doesn’t always mean unbeatable. Their legacy is unassailable, yet modern warfare belongs to adaptability, not nostalgia. You don’t need to be the best. You just need to get the job done. And on that score, they still deliver. Just not by a mile.
