WASHINGTON (DC News Now) -- President Jimmy Carter's funeral procession from Joint Base Andrews to the U.S. Capitol was a well-planned and highly coordinated effort involving members from every military branch. Included were U.S. Air Force Honor Guard members, who shared that the procession was the result of training and preparation. Airman First Class James Barnard was a part of the marching procession and spoke with DC News Now after President Carter's casket was brought to the Capitol Rotunda on Tuesday. Jimmy Carter funeral: How to pay respects, things to know "Sometimes it can be a little bit sad that somebody has passed away," he said, sharing that the toughest part of the procession can be keeping his emotions under control. "You just take pride though that you're doing the right thing and then you're honoring the person properly." Carter's was his first state funeral. He said the U.S. Air Force Honor Guard had rehearsals for nearly two weeks, executed due to everyone's two-month-long training course. That course included learning rifle movements and training to stand motionless for hours, sometimes—like Tuesday—in the intense cold. "You'll do what we call 'stamina stands' where you could be standing for 30, 45 minutes or an hour. No movement. You have to stay motionless the entire time," he said. All of the training is to make sure the ceremony is profound with a focus on the fallen. In this case, a man Barnard admires for his service to his country in politics and the military. "We hope that we honored him properly," he said. "And he got the closure that he deserves because he served for many years not only in the Navy but also as a former Commander in Chief."
