"As this last group of brave combat soldiers heads home, we thank them for their service, professionalism and courage.
"The state of Iowa lost 56 service members in Iraq over the past eight years - a number multiplied many times over by the loved ones they left behind. We will continue to grieve with them and support them, and to honor their memories. They are the true heroes of this story, the best and bravest among us, and their contributions will not be forgotten."
