Tyler Grey: The Most Unlikely MOS To Make It Through Delta Selection
"Every time I thought I figured something out, some— I'd learn something else that would throw that off. Like, I, I literally have no idea. And I can tell you that guys that have been there 20 years, we've all— look, I'll straight up say we're all curious and trying to figure it out."
A former Delta Force operator reveals that the selection process standards remain completely unknown even to operators who served 20 years in the unit. Only one person at any given time knows the complete selection criteria, with approximately 10 people total having ever known the full standard throughout the unit's history. This creates what the operator describes as the 'best-kept secret in the military,' where candidates and even cadre running the course don't understand how final decisions are made.

About this episode

A former Delta Force operator provides rare insight into the selection and training process of America's most secretive military unit in this detailed interview. The guest reveals that Delta Force selection standards remain unknown even to operators who served 20 years in the unit, with only one person at any given time knowing the complete criteria. The 32-day selection course consists primarily of solo land navigation exercises that serve as an intense psychological test, with candidates simply disappearing without explanation when they quit or are cut. The operator describes witnessing extraordinary athletes fail unexpectedly, including one candidate who ran a 16-mile ruck march at a five-minute-per-mile pace but was gone within a week. The guest's own Operator Training Course class graduated only two enlisted operators after approximately 18 months, despite starting with around 50 candidates, demonstrating the unit's uncompromising standards. He describes discovering teammates from unconventional backgrounds, including a former Navy hardhat diver who held the Badwater ultramarathon record for four years. The year-long OTC starts all candidates from zero regardless of background, teaching everything from basic rifle marksmanship through specialized commando skills that the operator describes as 'movie cool,' including aircraft assaults. He emphasizes that Rangers comprise the majority of Delta Force personnel compared to Green Berets, contrary to some public perception. The operator candidly discusses the constant process of proving oneself even after selection, describing how new graduates quickly realize their skills pale compared to veteran team members. He recounts his first deployment mission in Iraq chasing insurgent squirters across 2.5 miles while struggling to keep pace with the ultramarathon champion teammate. The interview provides unusual transparency into the culture, standards, and reality of serving in a unit where operational security remains so tight that selection itself constitutes what veterans call the best-kept secret in the military.
