A Special Forces soldier assigned to the 7th Special Forces Group (Airborne) gives his partner the hand-signal to descend at Eglin Air Force Base’s East Gate Pool Jan. 20 while participating in a scuba recertification training session. The procedures required one soldier to aid the other by providing the distressed soldier his oxygen supply while swimming together. The training refreshed the Green Berets' skills at underwater operations while preparing them for future missions.
