Chief Master Sgt. Tracie Darby, 167th Medical Group superintendent, demonstrates how to make cloth face masks from t-shirts to 167th personnel, April 7, 2020. The face mask contained three layers of fabric and included a pocket to hold a filter of the wearer’s choice. The Department of Defense issued guidance April 5, calling for all individuals on military installations to wear cloth face coverings when six feet of physical distance cannot be maintained in work centers and public spaces.
