What are the three types of North found on a military map?

• A. True North, Grid North, and Magnetic North
• B. True North, Geographic North, and Magnetic North
• C. Grid North, Geographic North, and True North
• D. True North, Grid North, and Geographic North

Answer: (A)

The main idea here is that a military map uses three distinct references for “north” that you need to understand for accurate navigation: True North, Grid North, and Magnetic North. True North points toward the geographic North Pole, the actual direction of Earth's axis. Grid North is the direction indicated by the map’s grid lines, which run along the map’s projection and may not line up exactly with true north. Magnetic North is where a compass would point, toward the magnetic pole, which shifts over time and differs from both true and grid north. A map also shows the magnetic declination (variation) between grid north and magnetic north, so you can convert directions between them when navigating in the field. Choosing the set that includes Magnetic North is essential because it accounts for compass readings in real-world navigation. Including Geographic North as a separate option would be duplicative with True North, and leaving out Magnetic North would omit the direction a compass points to, which is crucial for field use.
