NAV Course Instructors Aid 7CMBG HQ

Grid Size
-Zoomed out the map will have a grid of 1km by 1km.

-Zoomed in the map will have a grid of 100m by 100m.

Buildings
-Buildings are noted as gray squares on the map.

-The building may vary slightly from the square marked on the map.

Special Markings
-Some buildings are marked with special symbols to indicate things such as Churches which have a Cross shape.

-Mountains are denoted with triangles.

-High towers and obstructions also marked (Show Green Mountain tower).

Roads
-Main roads are bolder and easily visible from farther out.

-Smaller roads appear as you zoom in on the region.

-Dirt roads are last to appear and are often just two parallel black lines.

Contour Lines
-Show increase/decrease in elevation.

-Closer lines indicate steeper elevation.

-Spread out lines indicate minor change/flat ground.

Type of Terrain
-Hour-Glass Shape indicates Saddle

-Circle without number indicates a depression/bowl shape.

-Circle with number indicates a hilltop. Number indicates elevation above sea-level in meters.

-Elongated Circle with number indicates the top of a ridge.

-Elongated Circle without number indicates a valley.

Cliff
-Several lines stacked directly on top of each other. Severely steep and should be avoided for quick movement.

Solid Green
-Indicates a forest or heavily vegetated region.

-Provides heavy cover for both yourself and enemy targets.

-Camouflaged targets are better hidden in heavily forested areas.

Green Circles
a. Indicate individual plants of significant size.

b. Small filled circle indicates a bush.

Small Circle
-Indicates a small individual tree.

-Often times not a problem for rotary aircraft.

Large Circle
-Indicates a large individual tree.

-Will present a problem for aircraft.

Coordinates
-Indicate the location of an object on the map. Use the grid to determine the numbers for the coordinate.

-First part is from across the top, Second is from down the side.

-0000 is located in the NorthWest corner of the map.

4-Digit Coordinates
-Indicates a 1km x 1km area.

-Not accurate.

-Written/Read as "####"

-Example: "9238" :: 92 across the top | 38 along the side

6-Digit Coordinates
-Indicates a 100m x 100m area.

-Fairly Accurate.

-Written/Read as "######"

-Third number is taken from within the 1km of the first two numbers.

-Sixth number is taken from within the 1km of the 4th and 5th numbers.

-Example: "564214" :: 564 across the top | 214 along the side

Quadrant Reference
-Indicates a 50m x 50m area.

-Accurate.

-Reference number derived by projecting a North East South West compass rose onto the grid square.

-Written/Read as "###### NW/NE/SW/SE Quadrant"

-Example: "857547 NE" or "857547 NE Quadrant" :: 857 across the top | 547 along the side | NE Quadrant indicates the upper right section inside the grid.

8-Digit Coordinates
-Indicates a 10m x 10m area.

-Precise.

-Reference number derived by projecting another 10x10 grid onto the 100m x 100m grid square.

-Usually must be eyeballed.

-Written/Read as "########"

-Fourth number is taken from within the 100m of the first 3 numbers.

-Eighth number is taken from within the 100m of the 5th through 7th numbers.

-Example: "56432146" :: 5643 across the top | 2146 along the side.

Splitting a Coordinate
-For when you receive a coordinate and must decipher it.

All numbers
a. Split the number in the middle.

b. Examples

-Such as "8245" = 82 across top | 45 down side.

-Such as "821456" = 821 across top | 456 down side.

-Such as "82194562" = 8219 across top | 4562 down side.

Reference after
a. Split the number in the middle.

-Find Grid Reference first then the reference area.

b. Examples

-Such as "821456 NW" or "821456 NW Quadrant" = 821 across top | 456 down side | Then the upper right corner of the 100m X 100m area.

The Arrow
-The Arrow and heading numbers always point North.

-The heading under the line is the way you are facing.

View Slot
-Look through the slot at an object/target and the heading can be read.

Compass Correlation
-Continue looking at the target or Reference Point (Hereby known as RP).

-Open the map without looking away and the compass will be set to the same heading as the out-of-map compass.

Triangulation
-Determine your exact location using objects you can identify and locate.

Reference Point (RP)
-An object/place/thing that you can recognize and locate on the map.

-Examples: Church; Tower; Hilltop; Town

-Use the compass and look through the slot at the RP. Place the metal line over the RP then open the map.

Map
-Place the outer tip of the compass on the RP. Place a point at the center of the bottom of the compass, and one on the RP itself.

Repeat
-Find another 1-2 RP's and do the same procedure for placing the points.

Determine Location
-Connect the dots (mentally or draw lines).

-Current location is where the lines cross.

Target Location
-Use to locate a target in order to call in support or identify the target.

Triangulate Position
-Use the above procedure to identify your exact location.

Compass
-Open Compass and place the metal wire on the target.

RP
-Look around the target for any objects that can help range the target on the map.

-Example: An infantry next to a building and near a tree. These objects can help locate the precise location on the map.

Coordinates
-Use one of the previously established methods to derive a set of coordinates.

-Most accurate is the 8-Digit, and then by quadrant.

Scanning
-When breaking for breath or stopping at cover, scan to look for targets.

-Scan 360 Degrees when moving alone.

-Use Binoculars or Scope to check possible targets at a distance.

Tracking
-Keep track of where you are and where your route is in order to prevent getting lost.

-Check map in regular intervals.

-Follow changes in enemy movements around you.

Movement
-Covers a variety of terrain types that affect movement.

Open Field
-Low amounts of cover.

-Scan ahead before entering field.

-If you come under fire, drop to the ground or seek nearby cover.

-Cross at the shortest point possible.

Forest
-Offers Lots of cover.

-Move in short breaks and keep scanning your surroundings.

-Stop before entering and before leaving in order to scan for enemies.

Broken Cover
-Move swiftly from cover to cover.

-Scan for targets at each break.

-Adapt route to follow cover.

Hills/Ridges
-Use the land to provide cover.

-Avoid Skylining/Silhouetting when possible.

-Crest at cover or stay low if none is around.

-Follow along the side of ridges when possible and if the route must not be altered much.
