Chief Master Sgt. Juliet Gudgel, AETC command chief master sergeant, said Jan. 31, 2018, during a three-day visit to North Texas that Sheppard AFB is leading the charge on challenging the status quo, training Airmen in a different and meaningful way, and employs equipment and innovation in a way that creates a new and exciting experience for new Airmen entering the Air Force. It’s the new process of developing Mach-21 Airmen using 21st century tools and technology.
