U.S. Air Force Senior Airman Aaron Coonts, 18th Operation Support Squadron air traffic control journeyman, uses cotton swabs to extract skin cells within his mouth to be sent for the C.W. Bill Young Department of Defense Marrow Donor Program on Kadena Air Base, Japan, Nov. 4 2014. The applications are sent to the program where the DNA is collected, tested and stored in a database. By applying, members are registering to be put on a list of possible matches to potentially donate bone marrow in the future if found compatible with a patient in need.
