Chuck Ayers was a short, slightly aged man who served as a career soldier in Alpha Squadron under Edmund Duke, defecting with the general to the Sons of Korhal on Antiga Prime. He abandoned the Sons of Korhal after the Fall of Tarsonis however, following Jim Raynor. Although Raynor did not completely trust Ayers, considering him a possible mole and keeping an eye on him as a result, Ayers proved to be nothing but an asset.
