Start with eligibility
Interest in an SAS Reserve unit is not the same as eligibility to undertake specialist selection. Applicants should obtain current information from official channels and understand any prerequisite Army Reserve service and training.
Processes can change; there is no substitute for direct confirmation from authorised recruitment personnel.
The value of firsthand accounts
Founder Deepak Shukla has publicly written about preparing to apply to 21 SAS. Personal experience can illustrate discipline, motivation and lessons learned, but it should not be mistaken for proof of selection completion or insider access.
The original series on DeepakShukla.com should remain attributed and linked as a personal account rather than copied here.
Preparation without speculation
Train consistently and sensibly for general fitness with qualified advice. We do not publish undisclosed selection methods, fabricated pass rates or performance thresholds presented as official.
If you want authoritative recruitment information, consult the Army rather than treating any independent website as an application portal.
Eligibility comes before a selection training plan
Interest in 21 or 23 SAS Reserve frequently begins with documentaries, veteran accounts or personal blogs. Those sources may explain motivation, but they cannot establish whether the unit is currently recruiting someone with your age, service background and eligibility. The first task is to contact an authorised Army Reserve recruiter and confirm the present public application route.
Some specialist activities require existing service or other prerequisites. Avoid treating a historic civilian application account as an enduring offer of direct entry. Current Army and unit advice must supersede anything written years earlier.
Firsthand accounts are context, not an endorsement
Project Selection's founder Deepak Shukla has publicly written about preparing for an application to 21 SAS Reserve and has personal endurance-sport experience. That is a perspective on motivation and preparation, not a claim of SAS service, selection completion or insider knowledge. The original story can be read through the About page.
Independent guides should be explicit about that distinction. A provider that implies a special-forces affiliation or advertises confidential selection knowledge without evidence creates a trust problem and potentially misleading expectations.
Useful questions before committing significant training time
Ask the official recruiter whether the current route is open, what service status or previous military experience is required, and which general fitness or medical requirements are public. If you are eligible, obtain the authoritative joining information for your actual assessment stage.
Build ordinary strength and aerobic foundations with suitable qualified guidance. Do not attempt unofficial load-bearing events, extreme deprivation drills or selection simulations based on a stranger's report. The best return on effort at this stage is verifying eligibility, preserving health and building a sustainable routine.
Try a relevant calculator or general practice exercise when it helps clarify this topic. No account, payment or official recruitment score is involved.
