The 82nd Airborne Division couldn't be more excited about the new family member.

A week before Chris Harris was killed by an explosive device in Afghanistan, his wife Britt Facetimed him from their home in Southern Pines, North Carolina. She wanted to surprise him with something she made. It was a onesie—Britt was expecting their first child and was due in March.

"When I told him, it was the happiest I'd ever seen him," said Britt, 26, told Good Morning America. "He was so excited."

Chris was a member of the 2nd Battalion, 504th Infantry Regiment, 1st Brigade Combat Team, 82nd Airborne Division, based in Fort Bragg. He and Britt had been married for less than a year before he was deployed.

Britt told GMA that her husband, an only child, called his fellow soldiers his "brothers."

"They were his family," she said. "Everyone that I've met, before Chris passed and after, if they're in the military, they've treated me like actual family or royalty, actually."

Determined to keep the soldiers who fought beside Chris close to their child, Britt asked them if they'd like to be the first to know the baby's gender. "They were really excited," she said. "I told them I would ship confetti poppers or something and they could be the first to know and feel included."

Sure enough, the poppers arrived in Afghanistan, and the soldiers filmed themselves opening them. With an American flag behind them, they cheered as they were showered in pink confetti.

"I probably watched it 100 times myself," Britt said of the video, which has since gone viral. "I was crying but smiling because their reaction was so wonderful."

Britt told GMA that she plans to name her daughter Christian Michelle Harris after the baby's father, Christopher Michael Harris.
