Sgt. Maj. PT
Capt. Jerrel Scriven, Joint Task Force-Bravo director of protocol, and Capt. Laura Miller, JTF-B adjutant, carry logs around the track at Soto Cano Air Base, Honduras, June 03, 2015. This is one of many exercises in the grueling workout known as “Sgt. Maj. PT,” a training session led JTF-B’s Command Sgt. Maj., Nelson Callahan, that encourages members to “lead by example, to break a sweat, to blast [their] core and to build unit cohesion” (U.S. Air Force photo by Capt. Christopher Love).
