U.S. Air Force Senior Airman Charlotte Stenzel, 60th Air Mobility Wing Command Post emergency actions controller, provides a visitor pass Nov. 21, 2018, at Travis Air Force Base, California. The command post is in a secure location due to the types of information that they can receive, such as operational reports and their ability to track every flight that comes in and out of the base.
