Q

Define an Adjust Fire Mission

A

Provides ONE round from the firing unit to adjust until effects are within 50 meters. After round is adjusted to within 50 meters, observer will announce “Fire for Effect.” You will use AF when you do not have an accurate Target Location.

Q

Define a Fire for Effect Mission (FFE)

A

No adjusting of the rounds is required. All guns (example: Battery=8 guns) will fire on the target after the call for fire is sent. You will use FFE when you have an accurate Target Location.

Q

Define and Immediate Suppression/Smoke Mission

A

Immediate Suppression or Immediate Smoke is unique in that it is sent in one transmission. This is to facilitate suppression of an enemy target. For example: Your unit is receiving enemy fire and you need to suppress that enemy to move to a better position. How many rounds you receive for that mission are based off Unit SOP.

Say “Correction , k” and wait for response of “Correction , Out

43
Q

What are the elements of a Method of Engagement in a CFF

A

DAT - Danger Close, Ammunition, Trajectory

44
Q

What is Danger Close in a CFF

A

When the TGT is 600 m or closer to the FO (Field Observer)

45
Q

What are some ammunition types in a CFF

A

HE, DPICM, WP, Smoke, Illumination

46
Q

What are the options for Trajectory in a CFF

A

High Angle and Low Angle (45 degrees and less for tubes)

47
Q

What is the default trajectory for Artillery

A

Low

48
Q

Who normally selects the ammunition in a CFF

A

FDC based on you SNAP TGT Description

49
Q

If the FO wants to pick the ammunition in a CFF, what should they do

A

They call for “In Effect” and name the ammunition that they want in the FFE round

50
Q

What advantage does a low trajectory have

A

Less susceptible to enemy radar

51
Q

What advantage does high trajectory have

A

Terrain such as hills can be shot over, Mobile Operations in Urban Terrain (MOUT)

52
Q

What is the standard trajectory for Mortars

A

High

53
Q

How many Methods of Fire and Control are there

A

3

54
Q

What are the methods of Fire and Control

A

WAT - When Ready (default/less control/faster response), At My Command (AMC able to mass fires and better effects such as shooting Mortars and Artillery at the same time), Time on Target (TOT will hit + or - 3 seconds but sync up with FDC first)

55
Q

What are the five rules of direction

A

OMG-10-4 Observer to Target, Mils, Grid, Nearest 10 mils, 4 digits

56
Q

What does observer to target mean

A

You view direction in relation to the FO looking at the target

57
Q

What does Grid mean in the five rules of direction

A

It’s the Grid Direction using a map and protractor

58
Q

How do you convert a Magnetic Azimuth to a Grid Azimuth

A

Add or Subtract the G-M Angle

59
Q

What does 10 Mils mean in the rules of direction

A

Send your direction to the nearest 10 mils however 1 mil is okay if you have equipment capable of that

60
Q

What does 4 digits mean in the 5 rules of direction

A

Always send a four digit direction so it’s not confused with degrees in any way

61
Q

What must the FDC know before using a Polar Mission

A

Your location

62
Q

What is the threshold for sending a vertical adjustment in a Polar CFF

A

35M

63

64
Q

How many parts are in a Message to Observer (MTO)

A

4

65

66
Q

When is the term “Shot” used

A

FDC sends this to the FO after each adjustment in the FFE phase and after the initial round of the FFE

67
Q

What does the FO say in response to a “Shot” command

A

Shot, Out

68
Q

When is the term “Splash” used

A

FDC sends this to FO when his round is 5 seconds from detonation so they can get ready to observe

69
Q

What is the response to a “Splash” transmission

A

Splash, Out

70
Q

What are the distances you correct within during the AF phase

A

L/R corrections less than 30m are not sent. Half of bracket distance.

71
Q

What is the OT Factor

A

Observer to Target Factor is used to determine the L/R deviation correction

72
Q

How do you calculate the OT Factors

A

Take the distance from the observer to the target, divide by 1000 and round to the nearest whole number. If it ends in a .5 round to the nearest EVEN whole number. If the distance is less than 1000 express OT factor as a decimal. (IE. 700m = .7)

73
Q

What is the Spotting

A

The number of mils between the round and the target that is measured with the binocular reticle pattern or the Hand method

74
Q

What is the order of Number and Direction when giving a spotting

A

Number then Letter

75
Q

What is the order of Number and Direction when giving the deviation correction

A

Letter then Number

76
Q

How many mils does five fingers spread equate to

A

300 mils

77
Q

How many mils does five fingers close equate to

A

180 mils

78
Q

How many mils does four fingers equate to

A

125 mils

79
Q

How many mils do the three middle fingers equate to

A

100 mils

80
Q

A

70 mils

81
Q

How many mils does the pointer finger equate to

A

30 mils

82
Q

What is the first range estimate based on

A

FO’s best judgement

83
Q

How does the Bracketing Principle work

A

You’re goal is to establish a bracket with one shot over and one short then continue to split the bracket in half

84
Q

Give an example of a correction

A

Correction L 30 Up 100

85
Q

What are the four parts to End of Mission

A

RRES - Refine, Record, End of Mission, Surveillance

86
Q

Give an example of EOM Transmission
