Legend:The legend or key provides an explanation of the symbols and colors used on the map. It is essential for interpreting the map’s features, such as roads, buildings, vegetation, and elevation.
Grid System:The grid system overlays the map with a series of horizontal and vertical lines, forming squares called grid squares. Each grid square has a unique identifier, allowing for precise location determination using coordinates.

Locating Points Using Coordinates

Coordinates are used to pinpoint specific locations on a map. The most common coordinate system used in military maps is the Military Grid Reference System (MGRS). MGRS uses a combination of letters and numbers to identify a specific grid square.

Grid Zones:The MGRS divides the Earth into 60 grid zones, each spanning 6 degrees of longitude.
Grid Squares:Each grid zone is further divided into 100,000-meter grid squares, identified by a two-digit number.
Coordinates:Within each grid square, smaller grid squares are defined using a combination of numbers and letters. For example, the coordinates “10S E234567” indicate a specific point within the grid square “E234567” in grid zone “10S”.

Interpreting Terrain Features

Maps use various symbols and techniques to depict terrain features. Understanding these representations is vital for navigating challenging terrain.

Elevation Contours:Elevation contours are lines connecting points of equal elevation on the map. The closer the contours, the steeper the slope. Contour intervals represent the difference in elevation between adjacent contours.
Relief Shading:Relief shading uses light and dark tones to simulate the appearance of hills and valleys. Darker areas represent lower elevations, while lighter areas represent higher elevations.
Symbols:Various symbols represent features like roads, buildings, vegetation, and water bodies. These symbols provide valuable information for navigating the terrain.

Compass Techniques

Navigating the terrain requires knowing your direction, and that’s where the compass comes in. It’s a crucial tool for determining your bearing and staying on course. It’s like having a tiny, magnetic guide to the North Pole, always pointing you in the right direction.

Understanding Compass Principles

The compass operates on the principle of magnetism. The Earth has a magnetic field, and the compass needle aligns itself with this field. The needle’s red end always points to magnetic north, which is slightly different from true north. This difference is called magnetic declination, and it varies depending on your location.

Orienting Yourself with a Compass

To orient yourself with a compass, you need to align it with the map. Here’s how:

Hold the compass level and turn the compass housing until the direction of travel arrow points to the desired direction on the map.
Then, rotate the compass bezel until the north arrow aligns with the north line on the map.
Army land navigation PPTs can be a valuable resource for learning the fundamentals of map reading and compass use, but they lack the interactive experience of building your own army. For a more engaging way to visualize and strategize your army deployments, consider exploring the legion army builder tool.
This allows you to experiment with different troop formations and unit types, which can be a helpful supplement to understanding the tactical concepts presented in land navigation PPTs.
Now, the compass is oriented, and you can use the compass bezel to read your bearing.

Navigating a Course with a Compass

To navigate a course, you need to set a bearing and follow it. Here’s how:

Determine the bearing from your current location to your destination using the map and compass.
Align the compass bezel with the bearing you’ve set.
Walk in the direction indicated by the direction of travel arrow.
As you walk, keep checking the compass to ensure you stay on course.

Compass Errors and Corrections

Compass errors can occur due to various factors, including:

Magnetic declination: This is the difference between true north and magnetic north. You can correct for declination by using a declination correction chart or by adjusting the compass bezel.
Magnetic interference: Metal objects, such as vehicles, can interfere with the compass’s magnetic field.
To avoid this, move away from such objects or use a compass with a built-in anti-interference feature.
