Fire for Effect

 The observer should strive for fire for effect with the first round or as soon as possible in the adjustment phase. When determining whether to fire for effect on the first round, the observer must consider the target location and how accurately the ship has been firing its initial rounds on previous missions. He must also consider the dispersion pattern of naval gunfire. If the first salvo is believed to have effect on the target, the best results are normally achieved by surprise fire. When fire for effect is desired, the observer specifies the number of salvos (and guns if different from that used in adjustment) and announces FIRE FOR EFFECT; for example, 6 SALVOS, FIRE FOR EFFECT or 2 GUNS, 6 SALVOS, FIRE FOR EFFECT.
