Maps & Terrain
Name the three minor terrain features.
Draw, Spur, Cliff.
What tool is used to plot coordinates?
A military protractor.
What are the three Norths?
Grid North, Magnetic North, True North.
What is a pace count?
The number of steps it takes you to travel 100 meters.
What two tools are required for resection?
Compass and map.
Name the five major terrain features.
Hill, Ridge, Valley, Saddle, Depression.
What is the rule for reading grid coordinates?
“Read Right, Then Up.”
What is a magnetic azimuth?
A direction read from a compass.
How do hills affect pace count?
Uphill increases count; downhill decreases it.
What is resection used for?
Finding your exact location on a map.
What do contour lines represent?
Elevation and shape of the terrain.
What accuracy does an 8-digit grid provide?
10 meters.
How do you compute a back azimuth?
Add 180° if <180°; subtract 180° if ≥180°.
Why is it important to log your distance traveled while navigating?
To track progress, ensure accuracy, and prevent drifting too far past your objective.
How many known points are needed for resection?
Minimum of 2.
Name six colors commonly used on a military map.
Black – Man-made features (roads, buildings, boundaries). Red-Brown – Cultural features & relief on red-light readable maps (contours, roads). Blue – Water features (rivers, lakes, swamps). Green – Vegetation (woods, orchards, jungle). Brown – Relief features (contour lines, elevation, sand). Red – Cultural areas, main roads, populated areas.
What is the purpose of the 1000-meter UTM grid lines?
a) To mark elevation changes. b)To marks magnetic north. c) To divide the map into 1km squares. d) To show contour intervals
c) To divide the map into 1km squares.
When moving, how do you stay on an azimuth?
Sight a distant object and walk to it.
What is a handrail?
A linear terrain feature like a roads, creeks, trails, streams, ridge lines, power lines, and fences.
What is intersection?
Locating a point by shooting azimuths from two known positions.
What is the declination diagram used for?
Converting between grid north and magnetic north.
What does MGRS stand for?
Military Grid Reference System.
What part of the lensatic compass shows degrees?
The bezel and dial.
What is dead reckoning?
Navigating by azimuth (direction ) and distance (steps) only.
When doing resection, what must you do with your magnetic bearings?
Convert them to grid bearings.
