Which statement about map grids on a standard combat map is true?

• A. They are numbered using alphanumeric coordinates
• B. They are always parallel to map edges
• C. They are irregularly spaced on different maps
• D. The distance between grid lines on a standard combat map is 1 kilometer

Answer: (D)

The grid spacing on a standard combat map is 1 kilometer. This means each grid square on the map represents 1 km of ground, so distances can be estimated quickly by counting squares or referencing the 1-km squares with grid coordinates. That uniform spacing is what makes the grid a reliable, common reference for navigation and targeting across maps and units. The grid lines are laid out in a regular pattern tied to the map’s projection, ensuring consistent distances everywhere on the sheet. While many maps label squares with alphanumeric margins, the crucial point being tested is that the distance between grid lines is 1 kilometer.
