Andy Stumpf: The Real Difference Between Regular SEAL Teams and DEVGRU
"At Development Group, yeah, you could probably do all those things, but it's not your main job. Your main job is to figure out a way to get to the threshold of the door and then own what's on the other side of the threshold. It's much more kinetically focused, in my opinion."
Andy Stumpf contrasts conventional SEAL team training—where he says operators cycle through many skill blocks—with DEVGRU, which he describes as concentrating heavily on close-quarters assault and repeat rehearsals in a kill house. He says that special operations forces are generally kinetic, but argues JSOC units are even more narrowly focused because commanders expect that specific capability in theatre.

About this episode

Mike Ritland interviews former Navy SEAL Andy Stumpf about his upbringing, his route into the Navy in the mid-1990s, and what he says distinguishes conventional SEAL teams from Naval Special Warfare Development Group (DEVGRU). Stumpf describes growing up in Santa Cruz, California in a military family and recalls early exposure to construction work, as well as memories of his father struggling with what he later connected to wartime-related issues. He says he fixated on becoming a SEAL in adolescence, entered the delayed entry programme at 17, and left for boot camp after high school.

The conversation then turns to training pipelines and the culture of SEAL teams in the late 1990s and early 2000s, including Stumpf’s description of pre-9/11 deployments as largely standby postings. Stumpf says he screened for DEVGRU in October 2001 and argues that, at the time, even SEALs had limited ‘beta’ on the unit because it was geographically separated and candidates who did not pass selection often did not return to their previous commands.

On the differences between DEVGRU and regular teams, Stumpf emphasises resourcing: he says the unit’s budget translated into more new equipment, better facilities, and access to newer weapons and technology, including a remit to test and evaluate gear. He also characterises DEVGRU as more narrowly focused on repeated close-quarters assault and ‘kinetic’ mission sets than the broader, rotating training blocks typical of conventional SEAL teams.
