The direction shown is the gun-target (GT) direction, the only weapon shown is the same weapon selected through the WPN AMMO switch. Once the FO enters the FFE phase, also known as the initial azimuth. GT azimuth falls in the azimuth block of 4901-1499, the MBC operator can use the technical fire control (TFC) switch to engage the target (as directed by the FDC order).In the adjust fire mode, the MBC operator ensures the FO's direction is shown. At this point, the modification will be a plus if traversing left and a minus(-) if traversing right. Divide the area into equal segments: 350/3 = 116. Each mortar covers 116 meters of the target area. Multiply the even hundred by 4: 1 x 4 = 4. The remainder of the target width (16 meters) is covered by adding one round.
