### SECONDARY SECTOR OF FIRE

As marginal data, record the gun number, unit designation, and date in one corner of the sketch. For security, no unit designation higher than company is recorded on the sketch. If in a mechanized unit, also include the squad designation.

When an FPL is assigned, extend the basic symbol of the machinegun along that line and determine the extent of grazing fire. Sketch in a shaded blade on the inside of the FPL to represent the extent of grazing fire. If there is dead space along the FPL, it is shown by breaks in the shaded blade. Record the ranges to the near and far edges of the dead space and the extent of grazing fire along the FPL. Determine the magnetic azimuth of the FPL and record this azimuth in the sketch section below the shaded blade representing the FPL. Record the elevation reading and other pertinent data under their proper columns in the data section.

### TARGETS

Targets in the primary sector are shown on the range card sketch by numbers enclosed in circles. An FPL, when assigned, is ALWAYS labeled target number L Other targets are assigned subsequent numbers in the order of their tactical importance.

Wide targets in the primary sector are usually engaged in the center first. However, the initial burst can be positioned wherever the leader desires. The gunner first measures the entire target width. He writes the width in the data section as TW-20 (target width 20). He then lays on the point on the target where the initial burst is desired and traverses to one edge of the target while counting the clicks. The number of clicks he traverses and the direction he moves the muzzle must also be included in the data section--for example, TW-20/R7- This would tell the gunner that he was not laid on the center of the target initially- Furthermore, after the initial burst, he must traverse right 7 clicks to reach the right edge of his target and then back left 20 clicks to cover the entire target area. If the gunner were to lay on the left edge of his target, his remark in the data section would be TW-20/R20.

When field expedients are used to engage targets, they are sketched above the drawing of the targets.
