Call to Fire Flashcards
List the elements in a call to fire?
6
- Observer ID
- Warning Order
- Target location
- Target description
- Method of engagement
- Method of fire and control
Regardless of the method of target location used, the normal call for fire is: __________
Sent in 3 transmissions consisting of 6 elements
If the observer does not accurately describe this, the rounds may not be effective:
Target description
This consists of the type of mission and the size of the element:
Warning order
This is the most important part in the call for fire:
Target location
When used by the observer, this can reduce the sporadic enaggement of the target
Method of Fire and Control
This element tells the fire direction center who you are
Observer ID
Write an initial adjust fire request using the following information – you are blue 3, the FDC is red 6, location of the target is ZX534678, target is troops in the open, authentication is x-ray, HE in effect:
1: Red 6 this is Blue 3 adjust fire, over
2: ZX534678 over
3: Troops in the open, HE in effect, I authenticate X-ray, over
Who determines HOW the target will be attacked?
FDC
Is direction sent before or with the first subsequent adjustment?
before
When sending a grid mission, does the observer’s location need to be known by the FDC?
No
The term polar alerts the FDC that the target willm be located with respect to who’s position?
The observer’s
When sending a polar mission, must the observer’s locastion be known to the FDC?
Yes
Vertical shifts are sent to the FDC by using the terms:
Up and down if the difference between the observer and the target altitude is 33 meters or greater
You are an observer. The FDC knows your location. You see enemy movement on a ridgeline in the open. They are located on an azimuth of 1800 mils and a distance of 3800 meters from your location. Your call sign is Z82 and the FDC is R68. What is your call for fire?
1: R68 this is Z82 adjust fire polar over
2: Dir 1800, Dis 3800 over
3: Enemy movement on the ridgeline over
If a grid call for fire is the standard, what is the most preferred?
Shift from known point
When conducting a shift mission, the observer does not need a map. What must the observer know?
The known point
The lateral shift is:
A left or right correction that brings the round onto the observer target line
The Lateral Shift has been determined:
To get Lateral Shift, you multiply: _____
The shift factor by the deviation. This is rounded to the nearest 10 meters
The Shift Factor
The Shift Factor is the formula used to convert: _________
the deviation from mils to meters and brings the strike of the round onto the OT line
When the deviation is needed quickly, you can: _______
Use the field expedient hand method to obtain deviation
You observe an enemy convoy stopped in the open. They are located 4 fingers to the right and 300 meters above your known point (AC1556). Your direction and distance to your known point is 500 mils and 3400 meters respectively. Your call sign is Z56 and the FDC is N18. What is your call for fire?
1: N18 this is Z56 adjust fire, shift AC1556 over
2: Dir 625, right 425, add 300, over
3: Enemy convoy stopped in the open, over
What is the term used to identify the spot at which the rounds will be most effective?
Adjustment point
Creeping fires are used when the target is: ______
Danger close
The OT direction is sent at: ________
at the end of the initial call for fire, before the first adjustment
OT direction is sent in: ___________
Grid azimuth to the nearest 10 mils
What are the 2 types of adjustments?
Area and precision
During a polar fire mission the FDC must know the location of?
The observer
What is an adjustment point?
A well-defined point in the center of the target that the observer use to adjust fire on to
When calling a shift from known point mission what must you say after calling SHIFT in the first transmission?
The Known point number
FDC is responsible for: _____________
Deciding how a target will be attacked, based on the Target description sent by the observer
What are the 4 types of adjustment techniques for area adjustment?
Hasty, successive, creeping, and one round
What is divided by 1000 to get the shift factor?
The range from the observer to the well known point
