Instructors • SSG Chad Wilson • SSG Richard Schilling
Class Objectives • Determine Azimuth on the Map using a Military Protractor • Find your Location on the Ground using Resection • Determine a Movement route using a map
Determine Azimuth on a Map Using a Military Protractor Outer set of Numbers = MILS (not used) Inner set of Numbers = Degrees Reference Lines Center point
Determine Azimuth on a Map Using a Military Protractor • Place Center Point on your Start Point • Using Reference Lines and Grid Lines Align Protractor in a good North South Orientation • Find Azimuth on Inner Ring of Numbers • Place Small Mark on map at Degree • Using protractor as straight Edge draw line between Start Point and the Mark you Made This is Your Azimuth line.
Determine your Location on the Ground Using Resection • Define Resection -Resection is the method of locating one's position on a map by determining the grid azimuth to at least two well-defined locations that can be pinpointed on the map. For greater accuracy, the desired method of resection would be to use three or more well-defined locations.
Determine your Location on the Ground Using Resection • Orient the map using the compass. • Identify two or three known distant locations on the ground and mark them on the map. • Measure the magnetic azimuth to one of the known positions from your location using a compass. • Convert the magnetic azimuth to a grid azimuth. • Convert the grid azimuth to a back azimuth. Using a protractor, draw a line for the back azimuth on the map from the known position back toward your unknown position. • Repeat 3, 4, and 5 for a second position and a third position, if desired. • The intersection of the lines is your location. Determine the grid coordinates to the desired accuracy.
Determine a Movement Route using a Map • Shortest Route (straight Line) • Most Tactical Route (Stealth) • Safest Route
Determine a Movement Route using a Map • Shortest Route • Find an Azimuth and Go • Terrain? • Time of Day?
Determine a Movement Route using a Map • Most Tactical • Wont be Seen By Enemy • Use the terrain • Stay away from heavily traveled areas i.e. roads, trails. • Not necessarily quickest or safest
Determine a Movement Route using a Map • Safest Route • usually the easiest • Pay careful attention to terrain • Stick to improved roads and good trails • Defiantly not the shortest or most Tactical • Maybe the quickest
Determine a Movement Route using a Map • Find your Waypoints • What is a waypoint -A waypoint is a reference point in physical space used for purposes of navigation. • Use waypoints when you are changing direction or to verify your azimuth
Determine a Movement Route using a Map • Determine Azimuth and Distance Between Waypoints ***If Traveling By Road Waypoints are only needed when changing Roads***
