Specialist Kristen Pinnock participated in the tribute for the first time this year, telling WFLA, "I'm thinking about the families -- what they had gone through, what they still go through."

“It really pulls at your heartstrings as it reminds you that we’ll always be there. We’ll always honor our guys,” Staff Sgt. Jason Kohne said.

It takes nearly 1,000 soldiers to complete the ritual, and they also perform the same task at U.S. Soldiers’ and Airmen’s Home National Cemetery in Washington, D.C.

"I would do this every single year I could until I retire, if I could," Army Pvt. Wes DeFee said told The Washington Examiner. "It's such an honor to help the families and support them with honor and respect."
