Airmen assigned to the 820th Base Defense Group and 105th Base Defense Squadron pose for a photo with Tech. Sgt. Joseph Lemm’s wife, Christine DeGuisto and son, Ryan, during a memorial service, Oct. 17, 2017, at the 84 Precinct station house, in Brooklyn, NY. While Lemm was a member of the 105th BDS, the unit trains closely and often deploys with the 820th BDG. Due to the high-stress training and deployments, the lines begin to blur and these Airmen become close-knit families. (Courtesy photo)
