Extreme close up of Staff Sgt. Latisha Gosha-West, a 624th Aeromedical Staging Squadron medical technician, practicing her wound closure skills on a pig foot. Pig feet and chicken legs are used for practice because they closely resemble what it's like to perform sutures on a patient with a laceration. In order to maintain a high level of proficiency, 624th ASTS medical technicians practice different skills each drill weekend. The 624th ASTS is part of the 624th Regional Support Group, which is the largest Air Force Reserve presence in the Pacific. (U.S. Air Force photo/Master Sgt. Daniel Nathaniel)
