The FBI honors its Special Agents killed in the line of duty as the result of a direct adversarial force, or at or by the hand of an adversary. The names of these agents, who are appropriately termed "Service Martyrs," are included on a permanent plaque so that their ultimate sacrifice will always be remembered. The inscription on this Service Martyr Plaque reads: "In memory of Special Agents of the Federal Bureau of Investigation who were killed in the line of duty as the direct result of an adversarial action." A total of 34 agents were designated as Service Martyrs as of September, 2001.
