Eiling is an older Caucasian man with blue eyes and gray hair. He wore a green, button up U.S. military uniform with sets of four stars on either side of his collar, indicating his rank. He also had his name on the right side of his shirt and other badges across the left.
During the Vietnam war, Colonel Eiling was the head of a weapons smuggling ring, though he kept to the background, and set up Lt. Yarrow as the "actual" leader. After Capt. Nathaniel Adams found out about the smugglers, Eiling and Yarrow framed him for the murder of General Lemar, who had become a liability. Eiling was the judge at Adams's court-martial. He married his widow, and raised his two children, Peggy and Randy, as his own.
Back in his office, he met with accomplice Alec Rois. He was quite pleased that Yarrow took the fall for the smuggling ring, as well as the murders on other key figures in the operation. Now that Captain Atom was his friend and ally, he could use him to his advantage.
