Private Keppler is a villain appearing in the TV series Combat!, played by Sasha Harden who also portrayed Colonel Kleist and other Nazi villains in the same series.
Keppler was a Heer soldier. He and his superior Sergeant Buehler searched a house for Lieutenant Gil Hanley, during which time Keppler stole a French woman's necklace. Later, he and Buehler were assigned to guard the Germans' campsite, but he snuck away to go and see the woman he'd stolen the necklace from, and her mother tried to hit him with a stool. The two fought over the stool, and Keppler punched her. As he attempted to have his way with her terrified daughter, he was seized from behind and stabbed by Hanley, who'd been hiding in the basement.
