The family will soon have one other member to cheer on its soldiers. Bradley's new wife Ashley Moss recently found out she is expecting the couple's first child in the spring.
"He'll be gone when she has the baby," Bonnie Hoagland said. "He's trying to take his leave right around the time she's delivering."
The boys' father Gene Moss, Bonnie Hoagland's first husband, credits Chris Hoagland for inspiring the boys into military service.
Gene Moss, who also has a 21-year-old step-son preparing to deploy in March, said he takes comfort knowing two of his sons, at least, will be together in Afghanistan.
"Anything could happen to them," he said. "You don't know what they're walking into."
The Moss boys were already involved with the Junior ROTC in high school when the Hoaglands were married in 2003 -- five days before the groom deployed to Afghanistan.
All four boys enlisted after they turned 18, Bonnie Hoagland said, except for Bradley who signed up at 17.
"It seemed like the right thing to do," Clayton said. "I'm pretty sure my step-dad had some influence."
The family's fifth child, however, may get some resistance if she decides to enter into the family trade.
Rachel has already shown some interest of following her brothers and step-father into the military when she's old enough. Bonnie Hoagland admitted she's already trying to dissuade her daughter.
"I don't know if I can give another one," she said. "I don't know if I can handle it.
Clayton said he's also doing his part to keep his little sister at home.
"I'd rather her stay here," he said, "go to college."
But for now, the family's focus is on it's Afghanistan-bound boys.
"I am very proud of them," Bonnie Hoagland said. "And I look foward to them getting home safely."
