So, you want to know how to join the SAS. First, congratulations: you have selected one of the most difficult career paths on Earth, which is bold, admirable, and slightly harder than assembling flat-pack furniture without blaming the instructions.
The Special Air Service, better known as the SAS, is part of the United Kingdom Special Forces community. It is famous for extreme selection standards, quiet professionalism, and the motto “Who Dares Wins.” But joining is not about looking dramatic in sunglasses, shouting motivational quotes, or owning a suspiciously large backpack. It is about meeting eligibility rules, becoming a trained service member, building serious physical and mental durability, and passing a selection process designed to identify people who can operate under pressure without falling apart like a cheap camping chair.
This guide explains the legitimate routes, eligibility basics, preparation priorities, selection stages, common mistakes, and real-world experiences connected with the topic. It is written for readers who want a clear, practical, SEO-friendly overview of how to join the SAS without getting lost in myths, television drama, or internet bravado.
What Is the SAS?
The SAS stands for Special Air Service. It began during World War II as a small raiding force operating behind enemy lines in North Africa. Its early work focused on surprise, endurance, independence, and unconventional thinking. Over time, the regiment became one of the world’s most respected special operations forces.
Today, public information describes the SAS as part of UK Special Forces. Its roles are often summarized in broad terms such as special reconnaissance, counterterrorism, direct action, hostage rescue, and working in difficult environments. The key phrase here is “broad terms.” If you are hoping for a step-by-step manual on secret missions, this is not that article. Also, please reconsider your browser history.
Can Civilians Join the SAS?
The answer depends on which SAS route you mean. The regular SAS, commonly associated with 22 SAS, traditionally recruits from trained members of the UK Armed Forces. That means a civilian usually cannot walk directly from a normal office job into regular SAS selection. You first need to join and serve in the military, complete basic and trade training, gain experience, and then attempt the relevant UK Special Forces selection pathway when eligible.
However, the SAS Reserve route is different. Public British Army recruitment guidance states that 21 and 23 SAS Reserve can process applications from male and female applicants, including people with no previous military service. Those applicants are normally sponsored into an Army Reserve unit first, complete basic and initial trade training, gain experience, and only then attempt SAS Reserve selection.
Regular SAS vs SAS Reserve
Regular SAS
The regular SAS is a full-time special forces career route for serving military personnel. Candidates generally come from the British Army, Royal Navy, Royal Marines, or Royal Air Force after completing their basic and initial trade training. Public information also notes that UK Special Forces has multiple pathways, including SAS, Special Boat Service, Special Reconnaissance Regiment, signals, medical, and reserve options.
SAS Reserve
The SAS Reserve includes 21 SAS and 23 SAS. Reserve service is not a casual weekend hobby where you occasionally jog in boots and tell people at parties you are “basically special forces.” It requires serious commitment, extended training, and willingness to deploy. Official information describes UK Special Forces Reserve applicants as needing to commit to intense training demands, overseas deployment, and operations.
Reserve units are located across regions including London and the South East, Wales, the M3/M4 corridor, East Anglia, the South West, the Midlands, Scotland, and the North of England. The exact administrative route may vary, so candidates should always verify current details through official Army recruitment channels.
Basic Eligibility: Who Can Apply?
Eligibility rules change, and special forces recruiting standards can be stricter than general Army standards. Still, public guidance gives several important principles.
Nationality
To join the British Army, nationality matters. British citizens can apply. Irish citizens can apply for the regular Army, while Irish citizens hoping to join the Army Reserve generally need to already live in the UK. Commonwealth application windows may open or close depending on recruitment policy and role availability. Refugees and asylum seekers are not currently eligible under public Army Jobs guidance.
Age
For the SAS Reserve, official public pages have listed specific upper age limits for applicants and for candidates beginning parts of selection. For example, public Army guidance has stated that applicants with no previous military experience must be no older than 47 years and 6 months when applying to join the Army Reserve for the 21 and 23 SAS route. Ex-Regular and Army Reserve applicants have also been listed with separate age limits for the Aptitude phase. Because age policies can change, do not rely on a screenshot, a forum post, or a guy at the gym named “Maverick.” Check official recruiting pages before applying.
Medical Standards
All applicants must meet medical entry standards. The Army medical process looks at current health and medical history because military service can be physically and mentally demanding. Some conditions may delay or prevent entry, even if they do not affect everyday life. This is not personal; it is risk management. The hills do not care that your knee “only hurts when it rains.”
Fitness
Army fitness tests and role-specific standards exist before anyone gets near special forces selection. Public Army Jobs guidance describes fitness assessment as part of the application process, with standards depending on the chosen role. For SAS preparation, general fitness is only the beginning. Candidates need endurance, strength, load-carrying ability, swimming confidence, recovery discipline, and injury resistance.
The Main Route: How to Join the SAS Step by Step
Step 1: Decide Whether You Mean Regular SAS or SAS Reserve
If you are not already serving, the SAS Reserve may be the more direct public route to explore. If you want the regular SAS, the first move is usually joining the UK Armed Forces, completing training, serving in a role, and building the experience needed to volunteer later.
Step 2: Meet General Army Eligibility Requirements
Before dreaming about berets, mountains, and dramatic music, you need to meet basic Army requirements: age, nationality, medical standards, background checks, and fitness. This stage may include online applications, recruiter contact, assessment center visits, medical checks, and fitness testing.
Step 3: Complete Basic and Initial Trade Training
For serving personnel, completing basic and initial trade training is essential before attempting UK Special Forces pathways. For civilian applicants entering the SAS Reserve pipeline, official guidance indicates they are first directed into an appropriate Army Reserve unit to complete initial training and gain experience.
Step 4: Build Military Experience
Experience matters. The SAS is not looking for people who merely enjoy hard workouts. It needs mature, disciplined, reliable service members who can function in uncertain conditions. That means learning soldiering basics, fieldcraft, navigation, teamwork, leadership, communication, and how to stay useful when cold, tired, hungry, and surrounded by people pretending they are not also cold, tired, and hungry.
Step 5: Attend the UKSF Briefing Course
Public information describes the UKSF Briefing Course as the first step before selection. It is a demanding assessment and information phase that introduces candidates to the standards required and evaluates whether they should progress. Reports and official material have described it as a six-day course involving physical, mental, swimming, and navigation-related elements.
Step 6: Attempt Selection
Public British Army information describes the Aptitude phase as involving progressive timed marches over difficult terrain, culminating in a demanding endurance march. Reserve public guidance has also referred to extended full-time selection periods. The purpose is not just to test who can move fast while carrying weight; it is to identify resilience, judgment, motivation, and the ability to keep making decisions when the body is loudly filing complaints.
What Selection Is Really Looking For
Selection is not a bodybuilding contest. It is not a personality contest either, which is a relief for many extremely fit people with the conversational warmth of a refrigerator. The process is designed to test a broad set of qualities.
Endurance
Candidates must cover distance over rough ground while carrying weight. That means aerobic capacity, strong legs, durable feet, efficient movement, and the ability to recover quickly.
Navigation
Map reading is repeatedly emphasized in public guidance. Candidates who train only their lungs and legs but neglect navigation may discover that being extremely fit in the wrong location is still being wrong.
Water Confidence
Public information has highlighted swimming and water-related tests as areas that can catch unprepared candidates. That does not mean you need to be Aquaman. It means you should be calm, competent, and practiced in the water.
Mental Resilience
Selection tests motivation, emotional control, decision-making, and the ability to continue after discomfort stops being a visitor and moves in permanently.
Maturity and Judgment
Official descriptions of SAS Reserve work emphasize maturity and sound judgment. This matters because special operations environments can be complex, politically sensitive, and strategically important.
How to Prepare for SAS Selection
Build a Strong Aerobic Base
Start with consistent running, hiking, cycling, rowing, or swimming. The goal is not one heroic workout followed by three days of walking like a broken shopping cart. The goal is repeatable endurance. Build gradually, track progress, and avoid sudden jumps in volume.
Train for Load Carriage Carefully
Loaded marching is a specific skill. Running a fast 5K helps, but it does not automatically prepare your shoulders, hips, knees, ankles, and feet for carrying weight over hills. Add loaded walking progressively, use sensible footwear, and practice foot care. Blisters are small, humble things that can destroy large, confident plans.
Practice Navigation
Learn map symbols, contour lines, bearings, pacing, timing, grid references, and route planning. Practice in daylight before making things harder. The goal is calm competence, not wandering dramatically into a sheep field and calling it “advanced fieldcraft.”
Get Comfortable in Water
Practice swimming, treading water, and controlled breathing. If swimming is your weakness, fix it early. Water confidence takes time, and panic is not improved by adding a stopwatch.
Strength Train Like an Athlete, Not a Show Pony
Useful strength includes legs, trunk, grip, shoulders, back, and injury-resistant joints. Squats, deadlifts, lunges, carries, step-ups, pull-ups, presses, and core stability can all help when programmed sensibly. The aim is performance, not mirror-based diplomacy with your biceps.
Prioritize Recovery
Sleep, nutrition, hydration, mobility, and rest days are not luxuries. They are part of training. Many candidates fail themselves before selection by arriving injured, under-recovered, or convinced that pain is always weakness leaving the body. Sometimes pain is your body submitting a formal complaint.
Common Mistakes Candidates Make
Training Too Hard Too Soon
Motivation is wonderful. Tendonitis is less wonderful. Build gradually. The selection process rewards durability, not a three-week motivational montage.
Ignoring Navigation
A strong runner who cannot navigate is a fast liability. Study and practice map reading until it becomes a practical skill, not a dusty memory from a training video.
Neglecting Swimming
Water tests may seem less glamorous than hill marches, but poor water confidence can end a candidate’s progress early. Train it.
Copying Internet Programs Blindly
Some online plans are thoughtful. Others appear to have been written by a caffeinated anvil. Use official guidance, professional coaching when available, and common sense.
Thinking Selection Is Only Physical
Physical ability opens the door. Character decides whether you stay in the room. Candidates need discipline, humility, teamwork, emotional control, and the ability to learn quickly.
What About Women Joining the SAS?
Public British Army guidance states that applications for the SAS Reserve are processed from male and female applicants. Wider UKSF briefing information has also described opportunities across genders and services, provided candidates meet the required training and eligibility conditions. Standards exist for the role; they are not designed as social media talking points. The practical message is simple: eligible candidates should prepare seriously and let the selection process decide.
How Long Does It Take to Join the SAS?
There is no universal timeline. For a civilian pursuing the reserve route, the process may include Army Reserve application, assessment, basic training, trade training, experience in a unit, briefing course, selection, and further training. For a serving soldier, sailor, marine, or airman, the timeline depends on current service, completed training, chain-of-command processes, course availability, performance, and readiness.
In plain English: it takes time. Anyone promising a quick “SAS in 30 days” plan is either joking, selling something, or dangerously fond of fonts that look aggressive.
Career Reality: Life Is Not a TV Show
Television loves shouting, mud, dramatic pauses, and night-vision footage. Real preparation is quieter. It looks like months of consistent training, early mornings, careful recovery, boring admin, repeated navigation practice, and learning to stay calm when nobody is clapping.
Reserve service also has real-life complications. Candidates may need to balance civilian employment, family life, training days, mobilization requirements, and long periods away for selection or operations. Public sources have described SAS Reserve service as flexible in some respects, but also demanding, with expectations around operational mobilization and extended training. In other words, it can fit around a life, but it will still rearrange the furniture.
Experiences Related to “How to Join the SAS”
People who research how to join the SAS often imagine one defining moment: the hill, the march, the final test, the dramatic finish. But the real experience usually begins much earlier, in small choices that do not look cinematic at all. It begins with choosing to run when the weather is miserable, learning map symbols while friends are streaming another episode, and admitting that swimming is a weakness instead of pretending water is “not your environment.”
A realistic candidate experience might start with someone in a normal civilian job who becomes interested in the SAS Reserve. At first, the dream is vague. They know the name, the motto, and maybe a few documentaries. Then reality arrives wearing boots. They learn that the route involves Army Reserve entry, assessment, basic training, trade training, unit experience, and only later a chance to attempt selection. This is where many people quietly disappear. Not because they lack courage, but because they wanted the destination without the road.
The candidates who keep going usually become more practical. They stop asking, “What is the secret?” and start asking better questions: Can I pass the medical? Can I commit the time? Can my family and employer handle the schedule? Can I navigate under pressure? Can I carry weight without getting injured? Can I be useful when tired instead of merely dramatic?
Training also teaches humility. A person may be strong in the gym but struggle on hills. A good runner may discover that carrying weight changes everything. A confident athlete may be humbled by a swimming test. Someone who loves endurance may realize that navigation requires patience and precision. The process has a way of exposing the difference between looking fit and being prepared.
Another common experience is learning the value of small systems. Foot care becomes a serious subject. So does packing, eating, sleeping, pacing, stretching, and managing nerves. The candidate who ignores hot spots on their feet because “it’s nothing” may soon learn that nothing can become a blister with a legal department. The candidate who practices navigation repeatedly may save energy because they are not wandering around conducting accidental tourism.
There is also a psychological shift. Early motivation often feels loud: big goals, big plans, big declarations. Later motivation becomes quieter and more durable. It shows up as consistency. It shows up as turning up to training without needing applause. It shows up as listening to instructors, accepting criticism, and improving without making excuses.
For serving personnel, the experience can be different but equally demanding. They may already understand military life, but UKSF selection is still a separate challenge. They must balance current duties, prepare around operational tempo, maintain professionalism, and avoid assuming that past success guarantees future selection. Experience helps, but entitlement does not.
The biggest lesson from experiences around joining the SAS is that preparation is not just physical. It is administrative, emotional, social, and practical. A candidate needs support, time, patience, and honesty. The dream may start with “Who Dares Wins,” but the daily work is closer to: who plans carefully, trains consistently, recovers intelligently, learns navigation, protects their feet, and does not quit the first time reality becomes inconvenient.
Conclusion
Learning how to join the SAS starts with understanding the difference between myth and process. The SAS is not joined through bravado, secret shortcuts, or motivational slogans typed over mountain photos. The legitimate route involves meeting eligibility requirements, joining the military or Army Reserve pathway, completing training, gaining experience, attending the UKSF briefing process, and attempting selection when properly prepared.
The best candidates prepare like professionals. They build endurance, strength, navigation skills, swimming confidence, resilience, and maturity. They respect the process, verify current official requirements, and understand that selection is designed to identify people who can operate under pressure with judgment and discipline.
If your goal is to join the SAS, begin with the basics: check official eligibility, speak to a recruiter, train intelligently, and build the kind of character that still works when motivation has left the building. The path is hard by design. That is exactly why the badge means something.
