1-8 Practical Exercise #4
Scenario: You are currently on patrol when you spot an enemy squad digging in
on a hilltop located southeast of your position. You are unsure of your position.
You are able to see the hilltop and also a water tower located in a northeasterly
direction from your location. Using resection, determine the 6-digit grid coordinate
of your position to within +/- 100 meters.
Click on the Hilltop Button
to complete the first part of this exercise and then click on the Water Tower
button to complete the second part of the exercise. The third part of the exercise
will require you to determine your position to within a plus or minus 100 meters.
Click on the respective icons when you need the lensatic compass, protractor,
and the GM declination diagram. Enter your answers in the white box when you
have completed the required tasks. At the end of the exercise, click on the
"DONE" button to check your final answer.
Correct! Click
the OK button to continue.
GOOD JOB! You have successfully
calculated the grid azimuth for your position.
Incorrect. Click
the OK button to try again.
Incorrect. Your answer is more than
+/- 100 meters off from your current
position. Please review your calculations
and try again.
Incorrect. The
correct answer is 91.
Enter this number and press Enter.
Incorrect. The
correct answer is 112
degrees (Calculation: 91 degress + 21
degree GM angle = 112 degrees).
Enter this number and press Enter.
Incorrect. The
correct answer is 292
degrees (Calculation: 112 degress + 180
degrees = 292 degree back azimuth).
Enter this number and press Enter.
Incorrect. The protractor is now in the
correct position. The index lines should
be placed on the center of the point.
Click the OK button to continue.
Incorrect. The
correct answer is 24.
Enter this number and press Enter.
Incorrect. The
correct answer is 45
degrees (Calculation: 24 degress + 21
degree GM angle = 45 degrees).
Enter this number and press Enter.
Incorrect. The
correct answer is 225
degrees (Calculation: 45 degress + 180
degrees = 225 degree back azimuth).
Enter this number and press Enter.
Incorrect. The
protractor is now in the correct position.
The index lines should be placed
on the center of the point.
Click the OK button to continue.
Incorrect. Your
current position
is 088893. Use the navigation buttons
