Moving target
Observers must be proficient at engaging
moving targets of opportunity and in
planning and executing planned fires
against targets that will be moving at afuture time of attack.

Target of opportunity: is a target that appears
during combat and against which no attack has
been prearranged. Often, the observer must
quickly initiate the fire mission to alert the firingunit, while simultaneously estimating the
intercept and trigger points.

Planned target: is a target upon whichfires are prearranged. The degree of
prearrangement varies, but some prior
coordination or action is done to
facilitate engagement. Planned targets
may be further subdivided into
scheduled, on-call, and priority targets.

MOVINGTARGET CALCULATIONS
DETERMINETARGETDIRECTIONANDSPEED
After acquiring the target, the observer tracks it
until he is sure of the direction in which it is moving.As the target moves from point A to point B
the observer can use one of three methods to
determine its speed.

THREE METHODSTO DETERMINE
SPEED
Estimation Method: First the observer can estimate
The speed as follows:
Slow = 3 meters per second (7 miles per hour)Medium = 5 meters per second (11 mph)
Fast = 8 meters per second (18 mph)

THREE METHODSTO DETERMINE
SPEED
the target moves the observer lases it and
converts the polar data to grid locations forpoints A and B.
Then he determines how far the target
moved by measuring the distance betweenpoints A and B and rounding to the nearest 1
meter.
LASERMETHOD:

He divides the distance traveled by the
time interval between points A and B to
determine the target speed in meters per
second.

THREE METHODSTO DETERMINE
SPEED
As the target moves across the reticle pattern, the
observer measures the number of mils traveled to thenearest 5 mils.
He multiplies that number by the OT factor to
convert the distance traveled by the target to meters.
Reticle Pattern Method:
-

PREDICTTHE INTERCEPTPOINT
Once the observer determines the speed and direction
of the target, he must predict the intercept point
the point or grid at which he wants to engage themoving target. To do this, he first gathers and adds
the following information:
1. Total processing time (observer, FSE, FDC andgun times).
2. Time of flight.
