Travel in automobiles represent a time of high vulnerability to kidnapping or assassination attempts. Victims are placed in situations in which their actions can be predicted and their mobility alternatives are reduced. Ambushes rely on surprise, mobility and speed, planning, and the confidence and decisionmaking ability of the attacker. Potential victims must plan their defense to eliminate surprise, to deny potential attackers the information needed for planning, and to maintain an advantage in speed and mobility to permit escape. An analysis of the successful ambushes of Aldo Moro and Hans Martin Schleyer indicate the importance of alertness, the use of an armored car, and the use of various travel routes. Armored cars can be designed to absorb gun fire and return it while calling for help, and/or to absorb gun fire and escape. However, increased ability to absorb fire can reduce the capability to maneuver or escape. Security measures for cars should include tire protections, communications capability, protection from bombs, alarm systems, and antitheft devices. Protective driving techniques include ramming, J-turns, and bootlegger turns which allow victims to escape. In addition, security considerations for general travel plans, aircraft security, and special precautions for women are briefly noted. Illustrations and notes are included.
