AND CORRECT ANSWERS GRADED A+
⩥ Combination Checkpoints. Answer: The ideal type of checkpoint is
one that is either a combination of two line checkpoints or a line
checkpoint and a point checkpoint.
The advantages of combination checkpoints are:
-Since the linear feature stretches across your route, you cannot miss it.
Once at the linear feature, you need only follow it until you come to the
point feature. You are then at your checkpoint.
-Since you can accurately determine an exact point on the ground from
this type of checkpoint, it offers you information about distance and
direction.
⩥ __________ are used to find the location of an unknown point by
simultaneously occupying at least two known positions on the ground
and then map sighting on the unknown location.. Answer: Intersections
⩥ A ___________ is a planned magnetic deviation to the right or left of
an azimuth to an objective.. Answer: Deliberate offset
,⩥ EFFECTS OF METAL AND ELECTRICITY. Answer: Metal objects
and electrical sources can affect the performance of a compass.
However, nonmagnetic metals and alloys do not affect compass
readings. The separation distances are:
High-tension power lines
55 meters
Field gun, truck, or tank
18 meters
Telegraph or telephone wires and barbed wire
10 meters
Machine gun
2 meters
Rifle
1/2 meters
,⩥ INSPECTIONS. Answer: Compasses are delicate instruments and
should be cared for accordingly. A detailed inspection is required when
first obtaining and using a compass.
Your inspection should ensure:
-The floating dial's glass and crystal parts are not broken.
-The numbers on the dial are legible.
-The floating dial does not stick.
-The sighting wire is straight.
-The bezel ring produces distinct clicks when turned.
You should also periodically check the compass's accuracy at a
declination station. If your compass varies more than three degrees, you
should not use it.
⩥ CARE AND MAINTENANCE. Answer: The lensatic compass was
built to increase its serviceable life. Adherence to a very simple
maintenance regimen will significantly increase the life of the lensatic
compass.
Maintenance requirements are as follows:
-Rinse in fresh water, especially after exposure to salt water.
, -Brush off dirt and grime.
-Ensure the ridges on the bezel ring are free of dirt.
-Check movement of the rear sight to ensure it is free moving.
⩥ Which of the following are limitations that can impair the
performance of a lensatic compass? Select all that apply.. Answer: High-
tension power lines. YES
Field gun, truck, or tank. YES
Telegraph or telephone wires and barbed wire. YES
Machinegun. YES
⩥ What are the three types of north shown in the declination diagram?
Select all that apply.. Answer: True north,Magnetic north,Grid north
⩥ A __________ is a low point in the ground or a sinkhole.. Answer:
Depression
⩥ A map is defined as __________.. Answer: A graphic representation
of a portion of the Earth's surface drawn to scale, as seen from above.
