While he has been back home in Elk Grove Village for a couple of days, his family asked the Warriors Watch to give him a big welcome back.
The group escorted Giancaterino from church to his family's home. He talked to ABC7 Chicago about what he missed during his time in Iraq.
"Family, just being around friends, and it's amazing what people take for granted when you don't have it in your life for over a year," he said.
"[It is] a dream come true. Him to be three times over there and come back safely to us three times is unbelievable," mother Helen Giancaterino said.
"I would like to thank all the men and women who are in the service. They're in my prayers constantly," said father Don Giancaterino.
Giancaterino is the commander of 287th military police company and has been training Iraqi police.
