The actor offered his "deepest condolences" to the family of the sergeant.
Channing Tatum posted an emotional message to Instagram in memory of First Sergeant Peter Andrew McKenna after he was killed in Kabul, Afghanistan this weekend. He was 35.
"I'd like to offer my deepest condolences to the family of First Sergeant Peter Andrew McKenna, a brave soldier we had the honor of meeting in Afghanistan," Tatum wrote on Monday. "He tragically lost his life in an attack on one of the bases we visited on @theuso tour back in February. Let's always remember to thank the men and women who serve this county and so often sacrifice their own lives for ours."
In the image, the 35-year-old actor and McKenna are posing with Tatum's Magic Mike XXL co-star Adam Rodriguez and actor Nick Zano.
Both Rodriguez and Zano also shared the pic with their own moving tributes to the soldier.
"I had the pleasure of meeting this man in uniform during a USO tour in February of this year. Our meeting was a short one but he was the type of person who made an impression," Rodriguez wrote. "Please take the time, and not just right now, but every day, to remember what doesn't seem to be remembered in the news as often as it should. Soldiers (men and women) are farther away from home than most of us could ever comprehend and too many don't return. We must honor their lives by actively working toward the dominance of peace in every aspect of our lives and communities."

The actor concluded his caption: "I am glad to have met First Sergeant Peter Andrew McKenna from Bristol, Rhode Island and I wish him that peace in the next life."
Zano, 37, also shared his condolences following news of McKenna's death. "It is with a heavy heart to share the passing of an extraordinary serviceman I got to meet while in Afghanistan," the 2 Broke Girls actor wrote. "Peter McKenna was a highly decorated and respected member of our military who was going into his sixth tour of duty. Brave isn't the word that fully describes that sort of commitment to his country and brothers in arms."
Like Rodriguez, Zano was adamant about remembering those serving in the armed forces. "This is a reminder that our men and women are still there. No matter your view on these conflicts, we should always stand next to our servicemen," he continued. "To his parents, Peter and Carol McKenna of Bristol, Rhode Island, I am sorry for your loss. Thank you Peter... Rest in peace."
