In "Debt of Honor", he is again a field officer for the CIA's Directorate of Operations (DO). At the beginning of the novel, he and Domingo Chavez capture an Aidid-like African warlord, Mohammed Abdul Corp, and bring him to justice. Soon thereafter, they are sent to Japan to assess the national mood of the country, where Clark is undercover as a Russian reporter. When the situation turns into a war between Japan and the United States, they establish contacts with the opposition in the Japanese government and are also tasked to eliminate a pair of Japanese AWACS planes.
