One week of Jacks Valley is in the books for the Class of 2026. Do these pics bring up memories for anyone? What was your favorite (or least favorite) part of Jacks? Obstacle course, assault course, field training, firearms training, CBRNE (Chemical, Biological, Radiological, Nuclear, and Explosive materials) training? The basics are continuing to show they are #NoQuitAllGrit! Check out all of the photos on our Flickr page: Link in bio. #usafa2026 #warriorethos
