Map Training Class

1. Map Training Class LTCOL Cassady

2. Tasks Instruct Personnel on the following: -Identify Topographic Symbols on a Military Map -Identify Terrain Features on a Map -Determine a Magnetic Azimuth Using a Lensatic Compass -Orient a Map Using a Lensatic Compass -Locate an Unknown Point on a Map and on the Ground By Intersection - Locate an Unknown Point on a Map and on the Ground By Resection

3. Conditions Given: Highly Motivated Cadets, Lensatic Compass, Protractors 1:50,000 Scale Maps, and Mandeville high School grounds for Practical Exercises

4. Standard All Personnel Will be trained and confident in the use of a Military Map and Lensatic Compass For Finding Their Current Location and Determining What Resources are Nearby.

5. Safety Considerations - Weather Concerns - Proper Use of the Equipment - Reactions for Getting Lost

6. Identify Topographic Symbols Six Basic Colors: Black: Cultural (Man-Made) Features Other Than Roads Blue: Duh Brown: All Relief Features- Contour lines on Old Maps- Cultivated Land on Red-Light Readable Maps Green: Vegetation Red: Major Roads, Built Up Areas, Special Features on Old Maps Red-Brown: All Relief Features and Main Roads on Red-Light Readable Maps Any Additional Information Will Be Contained in the Map Legend

7. Terrain Features Five Major: Hill, Valley, Ridge, Saddle, Depression Three Minor: Draw, Spur, Cliff Two Supplemental: Cut, Fill

8. Hill

9. Valley

10. Ridge

11. Saddle

12. Depression

13. Spur

14. Draw

15. Cliff

16. Orient a Map Using a Compass Place the Map on the Ground or Any Flat Level Surface Using the Magnetic North Arrow Found in the Map Margin, Rotate the Map and Compass Until All are Pointing Towards the Top Index Line on the Compass

17. Practical Exercise Use a Map and Lensatic Compass to Orient a Map Using Terrain Association Orient a Map

18. Determine an Azimuth Using a Lensatic Compass Definition: A Horizontal Angle Measured Clockwise From a North Base Line. Use Cheek Method to Determine an Azimuth Back Azimuth: To Determine the Back Azimuth, add 180 Degrees if the Azimuth is 180 Degrees or Less, subtract 180 Degrees if the Azimuth is 180 Degrees or More

19. Practical Exercise Take Some Time to Get Comfortable Shooting an Azimuth With the Lensatic Compass and Computing a Back Azimuth Using a Map and Protractor Determine some Azimuths and Back Azimuths Practice Converting Compass and Grid Azimuths

20. Resection A Way to Locate One’s Position on a Map by Using at Least Two Well-Defined Locations Steps: • Orient the Map Using a Compass • Identify Two Or Three Distant Locations on the Ground and Mark them on the Map • Shoot a Magnetic Azimuth to the Distant Locations • Convert the Magnetic Azimuths to Grid Azimuths and compute the Back Azimuths • Draw a Line along the Back Azimuth from the Distant Location towards your Unknown Location. • The Intersection of the Lines is your Location

21. Practical Exercise Determine Your Present Location Using the Maps of the Waegwan Area Provided, a Protractor, and a Lensatic Compass

22. Intersection Intersection is Essentially the Same as Resection Just Backwards Using Two Known Locations you Will Determine the Location of an Unknown Area Steps: 1. Given two Known Locations, an Oriented Map, and a Compass 2. Shoot an Magnetic Azimuth from both Known Locations to the Unknown Location • Draw a Line from Both Known Locations to the Unknown Location Along the Azimuth • The Intersection of the Lines is the Location’s Coordinates

23. Intersection
