Airmen strain to move inches through mud, perfecting low- and high-crawl techniques during week one of the Combat Readiness School at Tinker AFB, Okla. Instructors drill into students the motto of “no one left behind” and watch the concept take hold as Airmen enter the pit as individuals, but struggle to the end as a team, encouraging and pulling each other to the finish. Fire team members from left are; Staff Sgt. Rich Brumbaugh, 349th Communications Squadron, Travis AFB, Calif; Staff Sgt. Christopher Kelley, 33rd Combat Communications Squadron, Tinker; Senior Airman Raid Alawar, 349th CS; and Airman Micheal Garner, 31st CCS, Tinker. (Air Force photo by Margo Wright)
