Lt. Col. Cory Christoffer reflects on his 20 years in the Air Force, and talks about what he thinks will make the Air Force a more cohesive unit. “It’s the little things that matter,” Christoffer said. “Giving a ride to an Airman walking across base, taking someone’s office garbage out, helping a peer through a fitness test, or even giving a smile, handshake, or verbal encouragement are just a few little things we can do to help each other as we work together to accomplish our mission.” (U.S. Air Force photo by Senior Airman Benjamin N.
