PROBLEM TO BE SOLVED: To force a person or an animal to be retreated without damage by charging an offensive odor organic compound such as an indole, a skatole or the like in a portable missile or the like, flying the missile by a radio controlled model aircraft or the like, and launching the missile toward an enemy. SOLUTION: A TV camera is mounted at a radio controlled model aircraft, and a portable missile in which an offensive odor organic compound such as an indole, a skatole or the like is charged is held at the aircraft. Such an aircraft is flown so as not to be disturbed by an opponent, approached to an enemy while observing a monitor, and the missile is launched to a most effective place of a target such as, for example, a bridge or a steering chamber in a fast ship or the like for violating a territorial waters while observing an image of the enemy. The compound is scattered from the missile impacted to the target to make the steerer of the ship impossible to steer due to the strong offensive odor. A magnesium ribbon is ignited at night to illuminate downward to enhance its aiming accuracy.
