|
|
Direction is determined to the nearest what |
10 mils |
|
|
How do you estimate OT distance |
By laser Flash to bang (time x by 350 = distance) Estimation |
|
|

Infantry company in the open, out
|
|
|
What does VT stand for |
Variable time |
|
|
What is variable time |
The time to target |
|
|
For a polar mission if they do not know your grid when should you send it |
You can send your grid before or after the intial request |
|
|
What is the most preferred call for fire method |
Shift from a known point |
|
|
How to locate a target by shift from a known point |
Identify to the FDC the known point to be used Determine the OT direction Determine the range shift Determine the lateral shift Determine the vertical shift, if necessary During the warno the known point is announced Ex: How thus is h44, fire for effect, shift aa7733, over |
|
|
What is the OT direction |
It is the direction from the observer to the target |
|
|
What is the preferred method for determining the direction the the target |
A grid azimuth |
|
|
What are range correction rounded too |
The nearest 100m |
|
|
How do you determine the lateral shift |
Determine the shift factor Determine the deviation Multiply the shift factor and deviation Express in meters, and round to the nearest 10m |
|
|
How do you determine the shift factor |
Determine the known point distance Divide the known point distance by 1,000 The sum of this will be multiplied by the deviation |
|
|
What is the deviation |
The difference, in mils between the known point direction and the target direction |
|
|
For the hand method for determine deviation what do the different fingers mean |
5 fingers is 300 mils A fist is 180 4 fingers is 125 3 fingers is 100 2 fingers is 70 1 finger is 30 |
|
|
To get the shift factor for shift from a known the number is rounded to the nearest what |
Decimal ex: 2,700=2.7 |
|
|
RALS stands for |
Right add, left subtract |
|
|
What is it called when you are spotting the round impact |
Spotting the round |
|
|
Successive bracketing is how many rounds |
5 2 rounds above 2 rounds below 1 round on target |
|
|
Hasty bracketing is how many rounds |
3 1 above 1 below 1 round on target |
|
|
When is creeping fire used |
When rounds are danger close |
|
|
How do you establish a bracket if the round impact is more than 400m, between 200-400m or between 100-200m |
More than 400m add or subtract 800m Between 200 and 400 add or subtract 400m Between 100 and 200 add or subtract 100m |
|
|
For adjusting fire during bracketing the OT is round to what |
The nearest even whole number |
|
|
What is it called when the OT is rounded to the nearest even whole number during bracketing |
Artillery expression |
|
|
