Which coordinate references are used when reporting target bearing to FDC?

• A. Random grid letters only.
• B. Grid/polar coordinates.
• C. Time of day coordinates.
• D. Elevation and azimuth only.

Answer: (B)

Target reporting to the Fire Direction Center uses two standard reference forms: grid coordinates and polar coordinates. Grid coordinates pin the target on the map grid (such as UTM/MGRS), giving a precise location that the FDC can plot for fire control. Polar coordinates describe the target from your position in terms of range and bearing, which is quick for immediate firing data and direction adjustments. Both forms are used so the FDC can locate and engage the target accurately, depending on what information is on hand or how the firing data will be processed. Time-of-day references aren’t used for locating targets, and elevation/azimuth alone isn’t the standard reporting format.
