At my command

The reticle tick marks are in increments of ___ mils.

10 mils

WHEN SENDING DISTANCE , YOU SEND IT TO THE NEAREST ?

100 Mils

When using the hand method to determine spotting/ Holding up 4 fingers is how many Mils?

125 mils

When using the hand method to determine spotting/ Holding up back of hand and just 4 half fingers/knuckles is how many Mils?

180 mils

When using the hand method to determine spotting/ Holding up 1 finger is how many mils?

What is the min. deviation correction sent?

30 meters

When using the hand METHOD TO DETERMINE SPOTTING/ Holding up 5 Fingers is how many Mils?

300 Mils

Which element of the cff do you specify ammo ?

5th element, method of engagment

When using the hand method to determine spotting/ Holding up 2 fingers is how many mils?

70 Mils

When determing range correction if the target is beyond the known point, his correction would (so many meters).

Add

What are the types of Missions withing a Warning Order?

Adjust fire Fire For Effect Immediate Suppression/SMK Suppression

When do send your location for a Polar msn?

Before you initiate your call for fire.

What are the methods of engagment?

Danger Close Ammunition Trajectory DAT

When ___________________the observer determines the difference (range change) in range from the known point and target

Determining Range Correction

When determing range correction if the target is short of the known point his correction would (so many meters).

Drop

What is the minimum number of digits required by FDC?

FDC can take up to 10

What are the three methods of target location?

GRID - Min 6 digits (may send 10) POLAR - Direction, Distance to TGT from your location, plus (U/D) altitude SHIFT FROM KNOWN PT - Direction, R/L, Add/Drop(+/-), (U/D) altitude

WHAT IS A STANDARD MISSION FOR ARTILLERY AND MORTARS, THAT IS NOT STATED IN THE WARNING ORDER.

Grid

WHAT IS THE STANDARD METHOD OF TGT LOCATION?

Grid

Two types of trajectory are:

High Angle Low Angle (Low angle is standard for artillery)

WHAT IS THE STANDARD AMMO FOR MTR AND ARTY ?

High Explosive

What's the standard trajectory for Artillery

Low Angle

WHAT IS THE STANDARD TRAJECTORY FOR ARTY?

Low angle

By using the reticle pattern inside a pair of _______ or _________ the observer can determine the number of mils between the impacting round and the target (DEVIATION CORRECTION).

Military binoculars or the Hand Method

How do you make deviation corrections?

OT factor times Spotting

When doing a shift mission, what does R represent in the worm formula?

Range to the Kn point from the observer and divided by 1000

How does one determine a target Desciption?

Size/Element Ex. 1st Platoon Nomenclature/Nature Ex. T-72/Tank Activity Ex. Stationary Protection Ex. In the Open SNAP

What does FDC need to know when doing a shift mission?

THE TGT NUMBER OR KN POINT YOU ARE SHIFTING FROM

WHAT INCREMENTS DO YOU SEND DIRECTION ?

Ten

When doing a shift mission, what does W represent in the worm formula?

The Left/Right lateral shift

The is used to determine the LEFT/RIGHT deviation correction.

The OT Factor

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

The Spotting

To determine the deviation correction you must multiply what?

The spotting times the OT Fact

What method of control does this define? STANDARD IS +/- 3 SEC RDS SHOULD BE IMPACTED ON THE GROUND WITH ROUNDS COMPLETE:

Time on Target TOT

To determine the OT factor when the OT range is greater than 1000 meters, the range from the observer to the target (OT distance) is what?

divided by 1000 and expressed as a whole number,if it ends in a .5 round to the nearest even whole number.(I.e. 1.5 is 2)

For an OT range less than 1000 meters what should be done?

the distance is divided by 1000 and expressed as a decimal/number (i.e. 0.7).
