Welcome to the Board Questions Podcast, where you can study for
your promotion or Soldier of theMonth board while driving,
commuting, or playing video games.
Today we will be focusing on questions about land navigation
that every E1 private and above should know shortly after
leaving basic training. Each of these episodes will
start with a pretest chapter, and if you confidently answer
(00:23):
every question, move on to the next most difficult episode and
test yourself there. If you didn't stick around and
start the lesson chapter where we will teach you each of the
answers in the lesson phase. Then the retest chapter will
give you a chance to try again. If you want to solidify your
answers subconsciously, the repetition chapter will repeat
(00:43):
the questions and answers, and you can solidify what you've
just learned by repeating them out loud.
Let's get started with the pretest, the pretest chapter.
Question One Which Army regulation covers land
navigation? TC3 Dash 25.26 Question 2 What
(01:07):
are the colors of a military mapand what do they represent?
Black signifies man made features such as buildings and
roads. Blue signifies water.
Green signifies dense vegetation.
Brown signifies relief features and elevation.
Red signifies cultural features like cities, forts, and
(01:29):
boundaries. On red light maps, red and brown
are combined. Question three.
What are the three types of north, true north, magnetic
north, and grid N? Question 4.
How many digits does your grid need to have to be accurate
within 1m Ten. Question 5.
(01:55):
How close will an 8 digit grid get you within 10 meters?
Question 6. How close will a six digit grid
get you within 100 meters? Question 7.
How many degrees are in a compass 360?
(02:19):
Question 8. What is a pace count and how
does a soldier determine their pace count?
For land navigation? A pace is equal to 1 natural
step, the average step about 30 inches long.
But every soldier step naturallyvaries, so it is imperative you
find your own pace count to use pace count accurately.
(02:41):
A soldier knows how many paces it takes to walk 100 M.
To determine this, walk an accurately measured course like
100 M or 600 M, and count the number of paces.
If using a 600 M course, divide the total paces by 6 to find the
average paces per 100 M. Each person who navigates
(03:02):
dismounted should know their ownpace count.
Question 9. What is a drawback of GPS in
tactical environments? It can be jammed, spoofed, or
loose signal in dense terrain. Question 10.
What do contour lines represent?Elevation and the shape of the
(03:24):
terrain. Question 11.
Where will you find the declination diagram of a map and
what does it represent? This is located in the lower
margin of large scale maps and indicates the angular
relationships of true north, grid north, and magnetic north.
Question 12. What is a back azimuth?
(03:48):
The opposite direction of an azimuth.
Question 13. How do you measure a straight
line distance between two pointson a map using a graphic scale
and a piece of paper? Lay a straight edged piece of
paper on the map so that the edge touches both points and
extends past them. Make a tick mark on the edge of
(04:09):
the paper at each point. Move the paper to the graphic
bar scale. Align the right tick mark with a
printed number in the primary scale so that the left tick mark
is in the extension scale. The primary scale gives the
whole unit distance and the extension scale gives smaller
increments. The lesson chapter If you feel
(04:30):
confident in your answers in thepretest, skip this episode and
move on to the next episode where the questions will be a
little harder. If you want to learn more, let's
dive into the lesson chapter. We will ask the question again,
give you the answer, and then explain why that is the correct
answer and what it actually means for you.
The Soldier question one Which Army regulation covers land
(04:54):
navigation? TC3 Dash 25.26 Land navigation
in the Army is governed by training Circular TC March 25th
26th Titled Map Reading and LandNavigation, this manual serves
as the Army's foundational doctrine for understanding maps
and navigating terrain. Soldiers at all levels, from new
(05:18):
recruits to senior leaders, use TC March 25th 26th to develop,
sustain, and evaluate land navigation capabilities.
To remember the numbers, think of this mnemonic.
You have 3 hours to find 25 points, but somehow you found
26. Did you overachieve or mess up?
(05:38):
Question 2. What are the colors of a
military map and what do they represent?
Black signifies man made features such as buildings and
roads. Blue signifies water.
Green signifies dense vegetation.
Brown signifies relief features and elevation.
Red signifies cultural features like cities, forts, and
(06:01):
boundaries. On red light maps, red and brown
are combined. Green and blue are easy to
remember, but the others may take some time.
Black means buildings so you canremember.
Black is man made features. Black equals buildings.
Brown shows elevation and is thecolor of the contour lines on
(06:22):
the map. Think brown equals dirt.
It's showing you how high the dirt is.
Red is cultural features like cities and military
installations. Think red equals enemy camps.
They'll splatter your blood everywhere if you step in the
red zone. Question 3.
What are the three types of north, true north, magnetic
(06:44):
north, and grid N? There are three types of north,
true north, magnetic north, and grid N True north points to the
geographic North Pole. Magnetic north points to the
magnetic pole as indicated by a compass.
This varies with the Earth's magnetic field.
Grid N refers to the vertical lines on a map grid system.
(07:08):
Understanding these differences is crucial when navigating with
a map and compass because directions can vary
significantly between them. To remember true is fixed
magnetic moves, grid is mapped. Question 4 How many digits does
your grid need to have to be accurate within 1 meter?
10 To pinpoint a location with 1m accuracy, a grid coordinate
(07:32):
must contain 10 digits, 5 for the easting and five for the
north thing. This level of precision is often
used for exact locations such asGPS waypoints or target
coordinates. Each pair of additional digits
increases the accuracy tenfold. Think of it like a digital zoom,
more digits, finer detail. 10 digits equals 10 fingers equals
(07:55):
pinpoint precision. Every two digits less will add
another zero to the accuracy. So remember 10 is the baseline
of 0 meters. 8 will get you 10-6will get you 104, would get you
1000 and so on. It all starts with 10.
Question 5. How close will an 8 digit grid
(08:17):
get you within 10 meters? An 8 digit grid coordinate
brings you within 10 meters of your target location.
It's more precise than a six digit grid, which is accurate
within 100 meters and is commonly used in tactical
operations for identifying positions like rally points or
resupply areas. Question 6.
(08:39):
How close will a six digit grid get you within 100 meters?
A6 digit grid coordinate gives you a location accurate to
within 100 meters. It uses 3 digits each for
easting and northing. This level of precision is
suitable for general location references such as grid square
identification in a sector. Question 7.
(09:04):
How many degrees are in a compass?
360° are the most common unit ofangle measurement when doing
land math. Think of someone hitting a 360
no scope. They made a full rotation when
they did it. Question 8.
What is a pace count and how does a soldier determine their
pace count? For land navigation, a pace is
(09:26):
equal to 1 natural step, the average step about 30 inches
long. But every soldier step naturally
varies, so it is imperative you find your own pace count To use
pace count accurately, a soldierknows how many paces it takes to
walk 100 M. To determine this, walk an
accurately measured course like 100 M or 600 M, and count the
(09:49):
number of paces. If using a 600 M course, divide
the total paces by 6 to find theaverage paces per 100 M.
Each person who navigates dismounted should know their own
pace count. A pace count measures how many
steps a soldier takes to cover aknown distance, typically 100
meters. Since everyone's stride is
(10:10):
different, soldiers determine their own pace count by walking
a 100m course and counting theirsteps for accuracy.
This is usually done multiple times over flat and uneven
terrain, and an average is calculated.
If using a longer course, like 600 meters, divide the total
steps by 6A mnemonic Know your pace to win the race.
(10:34):
Soldiers use beads or knots called Ranger beads to track
distances walked during navigation.
Question 9. What is a drawback of GPS in
tactical environments? It can be jammed, spoofed or
loose signal in dense terrain. While GPS offers precise
navigation, it's vulnerable in tactical environments.
(10:58):
Adversaries can jam the signal, rendering it useless, spoof it
to feed false information, or environmental factors like dense
forests and urban terrain can block the signal.
Because of this, soldiers are trained to navigate without
relying solely on GPS. The principle.
If the sky is blocked or the enemy jams, you better have a
(11:19):
map in hand. Question 10.
What do contour lines represent?Elevation and the shape of the
terrain. Contour lines on a map represent
the elevation and shape of the terrain.
Each line connects points of equal height above sea level.
The spacing of the lines indicates the steepness of the
(11:41):
terrain. Closely spaced lines mean a
steep slope. Wide spacing indicates a gentle
slope. This lets soldiers visualize the
ground shape even if they've never seen it.
Mnemonic contours connect the highs and lows.
Question 11. Where will you find the
declination diagram of a map andwhat does it represent?
(12:03):
This is located in the lower margin of large scale maps and
indicates the angular relationships of true north,
grid north, and magnetic north. The declination diagram is found
in the lower margin of large scale maps.
It illustrates the angular difference between true north,
magnetic north, and grid N. This is vital for converting
(12:25):
between compass readings, magnetic azimuths and map
azimuths. Grid azimuths The diagram
typically includes instructions for converting between these
azimuths. Think.
Find the triangle at the bottom to know where your compass and
map disagree. Question 12 What is a back
azimuth? The opposite direction of an
(12:48):
azimuth. A back azimuth is the reverse of
a direction or azimuth. To find it, subtract 180° from
your original azimuth if it's 180° or less, or at 180° if it's
more than 180°. For example, the back azimuth of
60° is 240°, and for 210° it's 30°.
(13:13):
It's used to retrace your steps or navigate back to your start
point. A trick to remember.
Flip 180 to head home. Question 13 How do you measure a
straight line distance between two points on a map using a
graphic scale and a piece of paper?
Lay a straight edged piece of paper on the map so that the
(13:33):
edge touches both points and extends past them.
Make a tick mark on the edge of the paper at each point.
Move the paper to the graphic bar scale.
Align the right tick mark with aprinted number in the primary
scale so that the left tick markis in the extension scale.
The primary scale gives the whole unit distance, and the
(13:54):
extension scale gives smaller increments.
It's important to note that the scale is typically measured in
larger increments throughout, with precise measurements at
just one end. You'll need to measure your
distance with the larger increments first, then fine tune
the rest. The Retest Chapter Now that we
have learned each topic, let's go over our answers in this
(14:15):
retest chapter to make sure you got it.
Question one Which Army regulation covers land
navigation? TC3 Dash 25.26 Question 2.
What are the colors of a military map and what do they
represent? Black signifies man made
(14:35):
features such as buildings and roads.
Blue signifies water. Green signifies dense
vegetation. Brown signifies relief features
and elevation. Red signifies cultural features
like cities, forts, and boundaries.
On red light maps, red and brownare combined.

digit grid get you within 100 meters?
Question 7 How many degrees are in a compass?
360 Question 8 What is a pace count and how does a soldier
(15:39):
determine their pace count? For land navigation, a pace is
equal to 1 natural step, the average step about 30 inches
long. But every soldiers step
naturally varies, so it is imperative you find your own
pace count to use pace count accurately, A soldier knows how
many paces it takes to walk 100 M.
(16:00):
To determine this, walk an accurately measured course like
100 M or 600 M and count the number of paces.
If using a 600 M course, divide the total paces by 6 to find the
average paces per 100 M. Each person who navigates
dismounted should know their ownpace count.
Question 9. What is a drawback of GPS in
(16:24):
tactical environments? It can be jammed, spoofed, or
loose signal in dense terrain. Question 10.
What do contour lines represent?Elevation and the shape of the
terrain. Question 11.
Where will you find the declination diagram of a map and
what does it represent? This is located in the lower
(16:47):
margin of large scale maps and indicates the angular
relationships of true north, grid north, and magnetic north.
Question 12. What is a back azimuth?
The opposite direction of an azimuth.
Question 13 How do you measure astraight line distance between
two points on a map using a graphic scale and a piece of
(17:10):
paper? Lay a straight edged piece of
paper on the map so that the edge touches both points and
extends past them. Make a tick mark on the edge of
the paper at each point. Move the paper to the graphic
bar scale. Align the right tick mark with a
printed number in the primary scale so that the left tick mark
is in the extension scale. The primary scale gives the
(17:33):
whole unit distance and the extension scale gives smaller
increments. The repetition chapter.
If it took you a second to answer those questions, would
recommend staying around for a rapid fire for the repetition
chapter. Feel free to move on to the next
difficulty anytime you feel likeyou have this down.

(12:25):
between compass readings, magnetic azimuths and map
azimuths. Grid azimuths The diagram
typically includes instructions for converting between these
azimuths. Think.
Find the triangle at the bottom to know where your compass and
map disagree. Question 12 What is a back
azimuth? The opposite direction of an
(12:48):
azimuth. A back azimuth is the reverse of
a direction or azimuth. To find it, subtract 180° from
your original azimuth if it's 180° or less, or at 180° if it's
more than 180°. For example, the back azimuth of
60° is 240°, and for 210° it's 30°.
(13:13):
It's used to retrace your steps or navigate back to your start
point. A trick to remember.
Flip 180 to head home. Question 13 How do you measure a
straight line distance between two points on a map using a
graphic scale and a piece of paper?
Lay a straight edged piece of paper on the map so that the
(13:33):
edge touches both points and extends past them.
Make a tick mark on the edge of the paper at each point.
Move the paper to the graphic bar scale.
Align the right tick mark with aprinted number in the primary
scale so that the left tick markis in the extension scale.
The primary scale gives the whole unit distance, and the
(13:54):
extension scale gives smaller increments.
It's important to note that the scale is typically measured in
larger increments throughout, with precise measurements at
just one end. You'll need to measure your
distance with the larger increments first, then fine tune
the rest. The Retest Chapter Now that we
have learned each topic, let's go over our answers in this
(14:15):
retest chapter to make sure you got it.
Question one Which Army regulation covers land
navigation? TC3 Dash 25.26 Question 2.
What are the colors of a military map and what do they
represent? Black signifies man made
(14:35):
features such as buildings and roads.
Blue signifies water. Green signifies dense
vegetation. Brown signifies relief features
and elevation. Red signifies cultural features
like cities, forts, and boundaries.
On red light maps, red and brownare combined.
(14:56):
Question three. What are the three types of
north, true north, magnetic north, and grid N?
Question 4. How many digits does your grid
need to have to be accurate within 1 meter?
10 Question 5 How close will an 8 digit grid get you within 10
(15:18):
meters? Question 6 How close will a six
digit grid get you within 100 meters?
Question 7 How many degrees are in a compass?
360 Question 8 What is a pace count and how does a soldier
(15:39):
determine their pace count? For land navigation, a pace is
equal to 1 natural step, the average step about 30 inches
long. But every soldiers step
naturally varies, so it is imperative you find your own
pace count to use pace count accurately, A soldier knows how
many paces it takes to walk 100 M.
(16:00):
To determine this, walk an accurately measured course like
100 M or 600 M and count the number of paces.
If using a 600 M course, divide the total paces by 6 to find the
average paces per 100 M. Each person who navigates
dismounted should know their ownpace count.
Question 9. What is a drawback of GPS in
(16:24):
tactical environments? It can be jammed, spoofed, or
loose signal in dense terrain. Question 10.
What do contour lines represent?Elevation and the shape of the
terrain. Question 11.
Where will you find the declination diagram of a map and
what does it represent? This is located in the lower
(16:47):
margin of large scale maps and indicates the angular
relationships of true north, grid north, and magnetic north.
Question 12. What is a back azimuth?
The opposite direction of an azimuth.
Question 13 How do you measure astraight line distance between
two points on a map using a graphic scale and a piece of
(17:10):
paper? Lay a straight edged piece of
paper on the map so that the edge touches both points and
extends past them. Make a tick mark on the edge of
the paper at each point. Move the paper to the graphic
bar scale. Align the right tick mark with a
printed number in the primary scale so that the left tick mark
is in the extension scale. The primary scale gives the
(17:33):
whole unit distance and the extension scale gives smaller
increments. The repetition chapter.
If it took you a second to answer those questions, would
recommend staying around for a rapid fire for the repetition
chapter. Feel free to move on to the next
difficulty anytime you feel likeyou have this down.

What is a pace count and how does a soldier determine their
pace count? For land navigation, a pace is
equal to 1 natural step, the average step about 30 inches
(19:03):
long. But every soldier step naturally
varies, so it is imperative you find your own pace count.
To use pace count accurately, a soldier knows how many paces it
takes to walk 100 M. To determine this, walk an
accurately measured course like 100 M or 600 M, and count the
number of paces. If using a 600 M course, divide
(19:26):
the total paces by 6 to find theaverage paces per 100 M.
