ELO C: Identifying a Grid Coordinate on a Military Map.
Action: Determine the grid coordinate within 100 meters of accuracy on a Military Map with in 10 minutes. Condition: In a classroom environment, given a student handout (Map), Protractor (GTA ) and a writing utensil. Standard: Demonstrate the ability to identify the Military feature in the grid coordinate on a Military Map (Student Handout) within 10 minutes. Student must accurately get 4 out of 4 correct to receive a go.
Grid Coordinate Scales. (Protractor) The primary tool for plotting grid coordinates is the grid coordinate scale. The grid coordinate scale divides the grid square more accurately than can be done by estimation, and the results are more consistent and accurate. Nomenclature: (GTA )
This device will include at least two coordinate scales, 1:25,000 and 1:50,000 meters. Make sure that when you use this device, you use the correct scale.
Military Coordinate Scale and Protractor 1/ 50,000 1/25,000 1/100,000
We use this scale for most Military Land Navigation Courses.
When reading the protractor each half tick mark equals half of that number. So you will have to estimate if the point does not line up flush with the tick marks.
Note. 1. A military map can help you spot your location accurately. The map has vertical lines (top to bottom) and horizontal lines (left to right). These lines form small squares 1,000 meters on each side, called grid squares. 2. The lines that form grid squares are numbered along the outside edge of the map picture. No two grid squares have the same number. 3. The precision of a point location is shown by the number of digits in the coordinates; the more digits, the more precise the location. For example: 1996—A 1,000-meter grid square —To the nearest 100 meters.
How close a Grid Coordinate can get you. 4 DIGIT GRID COORDINATE TO WITHIN 1,000 METERS A 6 DIGIT GRID COORDINATE TO WITHIN 100 METERS A 8 DIGIT GRID COORDINATE TO WITHIN 10 METERS (50 METER TOLERANCE)
You have to read the Map from the Right and Up! This means starting from the bottom Left Hand Side. Read Right to the Grid Line PRIOR TO your Target and then UP TO the Grid line Prior to your Target.
X Grid Zone Designator EH
Most Military Grid Coordinates are at least 8 Digit Grid Coordinates. The same principals apply as the 6 Digit Grid Coordinate except you will have to break down the numbers on the protractor to nearest amount. For example: The six digit grid coordinate reads EH The 8 Digit Grid Coordinate would read EH You will place the Protractor on the point and read where the Grid Line intersects the protractor and where the center of the point intersects the Protractor.
Proper Steps to Use Protractor: 1. Locate the grid square in which the point is located ; the point should already be plotted on the map. 2. The number of the vertical grid line on the left side of the grid square gives the first and second digits of the coordinate.
3. The number of the horizontal grid line on the bottom side of the grid square gives the fourth and fifth digits of the coordinate. 4. Place a coordinate scale on the bottom horizontal grid line of the grid square containing the point to determine the third and sixth digits of the coordinate. 5. Check to see that the zeros of the coordinate scale are in the lower right-hand corner of the grid square where the point is located.
6.Slide the scale to the right, keeping the bottom of the scale on the bottom grid line until the point is under the vertical (right-hand) scale. To determine the six-digit coordinate, the 100-meter mark on the bottom scale, which is nearest the vertical grid line, is the third digit of the number 115. The 100-meter mark on the vertical scale, which is nearest to the point, is the sixth digit of the number 813. Putting these together, you have
2 Letter Grid Identifier: To determine the correct two-letter 100,000- meter-square identifier, look at the grid reference box in the margin of the map. Place the 100,000- meter-square identifier in front of the coordinate. Example: UV

TAKE A BREAK!
ELO E: Determine the Distance on a Military Map using Contour Intervals and measurements.
Action: Determine the distance between counter intervals and ground distance on a Military Map. Condition: In a classroom environment, given a student handout (Map), Protractor (GTA ), Military Map (Student Handout) and a writing utensil. Standard: Demonstrate the ability to identify the distance between contour intervals and ground distance on a Military Map with 100% accuracy. The Soldier must accurately answer 4 out of 4 check on learning questions as well as identify the correct contour measurements.
CONTOUR INTERVALS: Before the elevation of any point on the map can be determined, the user must know the contour interval for the map he is using. The contour interval measurement given in the marginal information is the vertical distance between adjacent contour lines. To determine the elevation of a point on the map— Determine the contour interval and the unit of measure used, for example, feet, meters, or yards.
You can find this in the Marginal Information of your Map. It will look like the example below.
Find the numbered index contour line nearest the point of which you are trying to determine the elevation
Determine if you are going from lower elevation to higher, or vice versa. In figure below, point (a) is between the index contour lines. The lower index contour line is numbered 500, which means any point on that line is at an elevation of 500 meters above mean sea level. The upper index contour line is numbered 600, or 600 meters. Going from the lower to the upper index contour line shows an increase in elevation.
Determine the exact elevation of point (a), start at the index contour line numbered 500 and count the number of intermediate contour lines to point (a). Locate point (a) on the second intermediate contour line above the 500-meter index contour line. The contour interval is 20 meters, thus each one of the intermediate contour lines crossed to get to point (a) adds 20 meters to the 500- meter index contour line. The elevation of point (a) is 540 meters; the elevation has increased.
Determine the elevation of point (b). Go to the nearest index contour line. In this case, it is the upper index contour line numbered 600. Locate point (b) on the intermediate contour line immediately below the 600-meter index contour line. Below means downhill or a lower elevation. Therefore, point (b) is located at an elevation of 580 meters. Remember, if you are increasing elevation, add the contour interval to the nearest index contour line. If you are decreasing elevation, subtract the contour interval from the nearest index contour line.
Determine the elevation to a hilltop point (c). Add one-half the contour interval to the elevation of the last contour line. In this example, the last contour line before the hilltop is an index contour line numbered 600. Add one-half the contour interval, 10 meters, to the index contour line. The elevation of the hilltop would be 610 meters.
There may be times when you need to determine the elevation of points to a greater accuracy. To do this, you must determine how far between the two contour lines the point lies. However, most military needs are satisfied by estimating the elevation of points between contour lines
If the point is less than one-fourth the distance between contour lines, the elevation will be the same as the last contour line. In the previous figure, the elevation of point a will be 100 meters. To estimate the elevation of a point between one-fourth and three-fourths of the distance between contour lines, add one-half the contour interval to the last contour line.
Point b is one-half the distance between contour lines. The contour line immediately below point b is at an elevation of 160 meters. The contour interval is 20 meters; thus one-half the contour interval is 10 meters. In this case, add 10 meters to the last contour line of 160 meters. The elevation of point b would be about 170 meters.
A point located more than three-fourths of the distance between contour lines is considered to be at the same elevation as the next contour line. Point c is located three- fourths of the distance between contour lines. In the previous figure, point c would be considered to be at an elevation of 180 meters.
To estimate the elevation to the bottom of a depression, subtract one-half the contour interval from the value of the lowest contour line before the depression. In the figure pictured, the lowest contour line before the depression is 240 meters in elevation. Thus, the elevation at the edge of the depression is 240 meters. To determine the elevation at the bottom of the depression, subtract one-half the contour interval. The contour interval for this example is 20 meters. Subtract 10 meters from the lowest contour line immediately before the depression. The result is that the elevation at the bottom of the depression is 230 meters. The tick marks on the contour line forming a depression always point to lower elevations.
In addition to the contour lines, bench marks and spot elevations are used to indicate points of known elevations on the map. (1) Bench marks, the more accurate of the two, are symbolized by a black X, such as X BM 214. The 214 indicates that the center of the X is at an elevation of 214 units of measure (feet, meters, or yards) above mean sea level. To determine the units of measure, refer to the contour interval in the marginal information. (2) Spot elevations are shown by a brown X and are usually located at road junctions and on hilltops and other prominent terrain features. If the elevation is shown in black numerals, it has been checked for accuracy; if it is in brown, it has not been checked.
Measuring Distance on a Military Map: STRAIGHT-LINE DISTANCE: To determine straight-line distance between two points on a map, lay a straight-edged piece of paper on the map so that the edge of the paper touches both points and extends past them. Make a tick mark on the edge of the paper at each point.
To convert the map distance to ground distance, move the paper down to the graphic bar scale, and align the right tick mark with a printed number in the primary scale so that the left tick mark is in the extension scale METERS 1000
METERS meters Example:
CURVED-LINE DISTANCE To measure distance along a road, stream, or other curved line, the straight edge of a piece of paper is used. In order to avoid confusion concerning the point to begin measuring from and the ending point, an eight-digit coordinate should be given for both the starting and ending points. Place a tick mark on the paper and map at the beginning point from which the curved line is to be measured. Align the edge of the paper along a straight portion and make a tick mark on both map and paper when the edge of the paper leaves the straight portion of the line being measured.
Keeping both tick marks together (on paper and map), place the point of the pencil close to the edge of the paper on the tick mark to hold it in place and pivot the paper until another straight portion of the curved line is aligned with the edge of the paper. Continue in this manner until the measurement is completed.
When you have completed measuring the distance, move the paper to the graphic scale to determine the ground distance. The only tick marks you will be measuring the distance between are tick marks (a) and (b). The tick marks in between are not used.

Map Azimuth AB Pt. A EG Pt. B EG158822
Grid to Magnetic (GM) Angle To Convert Grid to Magnetic Azimuth Conversion Rule: Left – Add; Right – Subtract (LARS)
Presetting a compass Hold the compass level in the palm of the hand. Rotate it until the desired azimuth falls under the fixed black index line. Turn the bezel ring until the luminous line is aligned with the north seeking arrow. The compass is now preset. Assume the center hold technique and turn until the north seeking arrow is aligned with the luminous line. Proceed in the direction of the sighting wire.
Using the Compass –The lensatic compass is used to determine or follow magnetic azimuth both day and night. –There are two recommended positions for holding the compass when navigating: Hand to Cheek Method Center Hold Position
Recommend for a predetermined azimuth (DAY and NIGHT)
Hand To Cheek Technique The compass-to-cheek technique is used almost exclusively for sighting It is the best technique for this purpose
Compass use at night –All the luminous features on the compass will be used. –One click on the bezel ring equals; THREE (3) DEGREES
Attaining A Magnetic Azimuth Place the sighting wire on the object Center the sighting notch Look through the lens and read the Red line to obtain the magnetic azimuth
Back Azimuth –The reverse direction of a forward azimuth. –Is comparable to doing an about face. –MAY BE OBTAINED BY GRID (Protractor) MAGNETIC (Compass) –To obtain a back azimuth from an azimuth less than 180˚: Add 180 –If the azimuth is 180˚ or more Subtract 180
Back Azimuth Back Azimuth - azimuth taken from a distant point toward your location Used in Resection Numbers less than add 180 Numbers greater than subtract 180
Compass Precautions: –Handle with care –The dial is set with a delicate balance and shock could damage it. –Reading should never be taken near visible masses of metal or electrical circuits. –In cold weather, always carry the compass in its pouch, outside of your layer of clothing.
Effects of Metal and Electricity Metal objects and electrical sources affect the performance of the compass. Suggested separation distance: High-tension power lines55 meters Field gun, truck, or tank18 meters Telephone wire/barbed wire10 meters Machine gun2 meters Steel helmet or rifle½ meter

ELO: G Identify the proper technique during a Land Navigation Course.
Action: Demonstrate the ability to pay attention and take notes. Condition: In a classroom environment. Standard: Demonstrate the ability to use the information gathered in class to complete the Land Navigation Course.
Basic Land Nav Techniques: Navigating Past An Obstacle: Basically make a box around the obstacle. Accuracy counts, especially around larger obstacles. A graphical presentation is made of this on the next slide.
Pre-Plotting: Consolidate all grid coordinates for given mission and plot on map. Determine order in which points will be negotiated. Determine distance and direction to grid coordinate. Plot. *Convert azimuth to magnetic.
Use terrain features to verify your location on the ground. An individual’s pace count is not exact and must be verified by terrain association. Remember: Add up to 20% to distance if terrain is hilly or rough travel.
Determining Pace-count Note: The following should be done on flat terrain and dense/wooded terrain. Both pace-counts should be memorized by the soldier/cadet. Measure off a distance of exactly 100 meters. Start pacing and counting each time your left foot touches the ground. At the end of the 100 meters turn around and do it again. If your count is 68 steps then your pace-count is 68. Remember this number! Start pacing again through semi-dense vegetation/woods and count each time your left foot touches the ground. At the end of the 100 meters turn around and do it again. Remember this number!
Keep track of the paces you have walked in the field. It is too easy to forget and be off course. Try using some of the following. For every 100 meters try: –Move a bead on your pace counter –Place a mark in a notebook –Tie a knot in a string –Put a pebble in your pocket
Things that affect Pace Count: –Slope. Pace lengthens on a downgrade and shortens on an upgrade. –Winds. Tail winds lengthen pace while head winds shorten pace. –Surface. Loose surfaces tend to shorten pace. –Elements. Snow, rain and ice tend to shorten pace. –Clothing and equipment. Heavier burdens may shorten pace. –Stamina. Fatigue will shorten the pace. –Limited visibility/night. Unsure footing or the presence of unseen obstacles makes an individual wary and pace will tend to shorten.
Things that affect Pace Count: –Physical attributes. Example: One leg may be shorter than the other, causing a tendency to deviate from your course. –Unbalanced load. An unbalanced load may pull you slightly off-balance, causing deviation from your intended direction of movement. –Movement around obstacles. Right-handed people have an inherent tendency to move to the right around an obstacle, while left-handed people move to the left. A wise navigator alternates his direction of movement around obstacles
Once you receive your grid coordinates and go to your SP plot all the points on your Map. Determine the best method to travel and reach each point. Find the direction and distance to each point you plan to travel to. Document each direction and distance to the corresponding point. (Do not mix the points up) Store your map in a zip lock bag to avoid getting damaged by water or other materials. Ensure you place the map and notes in a secure location. Do not lose your map!!! Check after each point and randomly throughout the course.
Adjust Pace count for terrain throughout. Remember your pace count usually will not bring you smack dab in the middle of your point. To search the area at the end of your pace count you need to mark the point with tape, sticks or other materials in the general area. Begin to use the box method or other methods your comfortable with to search the area for your point. Remember not to stray to far off course. If you span a 100 meters using the box method return to the point you marked and try to terrain associate where the hell you are.
Check on Learning: 1.How many meters do you use to measure your pace count? 100 Meters 2.During Pre-Plotting your Grid Coordinates, what do you accomplish? The route to each point, the distance and direction to each point. 3.What do you use the box method for? Navigate around obstacles
Summary: Review: During this block of instruction you have learned different techniques to complete a Land Navigation Course.
ELO: H Identify how to do Intersection, Resection and Triangulation.
Action: Demonstrate the ability to identify intersection and resection grid coordinates. Condition: In a classroom environment. Given a Map, Protractor, Pencil, Paper and Compass. Standard: Demonstrate the ability to identify intersection and resection grid coordinates on a Military Map.
Intersection: We have two OPs located in front of our defensive position. Both OPs can see enemy activity. From OP1, the enemy activity is 32-degrees magnetic and from OP2, it is 322 degrees magnetic. The G-M angle is 18- degrees easterly. The magnetic azimuth from OP1 is 32 degrees. Convert this to a grid azimuth by adding the 18-degree G-M angle. The grid azimuth would be 50 degrees. Using the protractor, plot this azimuth on the map. Convert the 322-degree magnetic azimuth to a grid azimuth. the grid azimuth is 340 degrees. Using the protractor, plot this azimuth. The enemy is located where the line cross.
Step 2: -Convert azimuth from magnetic to grid G-M Angle: 18 east OP1: 032 magnetic = 050 grid OP2: 322 magnetic = 140 grid Step 1: -Identify / plot OPs or points of reference

Resection: Looking out from our position we can see a bridge. We determine the magnetic azimuth to its location to be 159 degrees. For the purpose of this problem, assume that there is a 1-degree westerly G-M angle. Convert from magnetic giving you a grid azimuth of 158 degrees. Next, we must convert this grid azimuth to a BACK azimuth by ADDING 180 degrees and plot the back azimuth of 338 degrees from the bridge. Our location is somewhere along this line. From our location, we can also see a larger road intersection. the road intersection is on a magnetic azimuth of 117 degrees. The grid azimuth is 116 degrees. Back Azimuth of 296 degrees. The back azimuth of 296 degrees is plotted from the road intersection. Your location is where the lines cross.
Step 2: -Convert azimuth from magnetic to grid G-M Angle: 01 west Bridge: 159 magnetic = 158 grid Road Int: 117 magnetic = 116 grid Step 1: -Identify / plot OPs or points of reference

Modified Resection Looking out from our position along Steam Mill Road, we can see the top of Hill 445 to our NW. We determine the magnetic azimuth to its location to be 299 degrees. For the purpose of this problem, assume that there is a 18-degree easterly G-M angle. Convert from magnetic giving you a grid azimuth of 317 degrees. Convert and plot the back azimuth of 137 degrees. Our location along Steam Mill Road is where this line crosses the road.

X Step 4: - Plot back azimuth from landmark (Hill 445) Step 5: - Plot your position where the line intersects the road you are on Step 6: - Drive on Airborne..
Triangulation: In order to locate yourself on the map by performing Triangulation, the basic idea is to compare your topographic map to what you are looking at, and identify terrain features that you are sure you can both see and associate with a feature on the map.
Just by looking at the map and the terrain, you should have a general idea of your location. Terrain recognition is important to pinpoint your location more accurately. Now you determine bearings to these features, and draw lines on the map corresponding to the bearing to those features. The use of at least three lines is recommended, and they should cross in a small triangle.
It is ideal to choose landmarks all around you, but sometimes this is not practical, as when on one side of a mountain range, with nothing distinguishable in the other direction. Choose landmarks as far apart as possible. Your best guess at your position will be in the center of the triangle that you draw. This process is illustrated on the next slide.
A few points should be made about Triangulation: First and most obvious, the more points you use, the more accurate you will be able to determine your position. Using more points will also tell if you have a "flyer," i.e. one bearing that you did wrong or terrain feature you misidentified. This line will be way off where the others meet. For these reasons it is preferable to look at as many features as possible.
Second, be very careful when using man-made objects. Keep in mind that maps are updated infrequently, and that man-made features usually change more frequently than the terrain features do.
Summary: Review: During this block of instruction you have received training on Intersection, Resection and Triangulation.
