Need stitches?
Airman 1st Class Richard Watson, 31st Medical Operations Squadron medical technician, practices suturing during a Readiness Skills Verification training course here Feb. 28. Suturing is sewing together two sides of a wound and medical technicians train on suturing using pig skin as models because it is similar to human skin.
