Sgt. Bobo, a military working dog, picks up the scent of simulated downed aircrew members during exercise Blue Chromite 16 in the Central Training Area, Okinawa, Japan, Oct. 28, 2015. Blue Chromite is a large-scale amphibious exercise that draws primarily from III Marine Expeditionary Force’s training resources on Okinawa. The location of the training allows participating units to maintain a forward-deployed posture and eliminates the cost of traveling to train. Bobo is with 3rd Law Enforcement Battalion, III Marine Expeditionary Force Headquarters Group, III MEF.
