M127 Company Iowa

I am hoping for a little help I am the granddaughter of Ervin Kuhlmann, he was in M127 Company and his records have been lost. My grandfather never talked about what he did while he was alive, he did his job and came home. Like many in my family I too am in the military and would like to know a little more about where he was. We found his original dd214 and award sheet in his truck with his uniform that was all. I know that he started in Fort Des Moines and went to California from there and went to Australia and spent time there as well as New Guinea. If anyone has any information in this group please let me know. thanks
