Trajectory

Because of the high muzzle velocity and the flat trajectory of naval gunfire, intervening terrain may prevent engagement of targets in defilade. Also, a reduced charge may be required to prevent ripping of the illumination parachute or to increase accuracy at short ranges. The observer or the ship can raise the trajectory, thereby increasing the angle of fall, by announcing REDUCED CHARGE. If this sub element is omitted in the call for fire, the ship will fire full charge. Once a reduced charge has been initiated, it can be terminated by the command CANCEL REDUCED CHARGE.
