The oldest living veteran in America, Richard Overton, is celebrating his 109th birthday on May 11, 2015. And he is celebrating it in style with milkshakes, cigars and burgers. Overton, a resident of Austin, Texas, served with the all black 1887th Engineer battalion during World War II. He fought in the Pacific War Theatre from 1942 to 1945. Overton has mixed emotions over his war experiences. Like many men of his generation, he didn't want to go to war but he did, and he did what he had to do.
