#### HASTY PROTECTIVE ROW MINEFIELD RECORD

Hasty protective row minefields/munition fields are recorded on DA Form 1355-1-R (Figure 8-4). A blank DA Form 1355-1-R is provided at the back of this publication; it can be locally reproduced on 8 1/2- by 11-inch paper.

Figure 8-4. Sample DA Form 1355-1-R

Use the following formula to determine the scale used on DA Form 1355-1-R:

Distance from RP to the farthest point in the minefield + 10 meters / 4 = scale

Example: 90 meters + 10 meters = 100 meters / 4 = 25 meters

The number 4 is a constant and represents the four concentric rings on DA Form 1355-1-R. Ten is added as a safety margin to ensure that the minefield/munition field sketch is entirely contained within the largest ring. The distance between rings is 2 centimeters; therefore, the scale used in this example is 2 centimeters = 25 meters.

The following step-by-step instructions are provided for completing DA Form 1355-1-R (see Figure 8-5):

From the RP, the leader measures the magnetic azimuth, in degrees, to a specific point on the right side (facing the enemy) of the tentative minefield/munition field. He determines the distance and records it in meters. He identifies the method of measurement in the remarks block of DA Form 1355-1-R (for example, distances were paced out and multiplied by 0.75 to convert the measurement to meters). This point, called B1 (if there are two rows), marks the beginning of the second row. A marker is placed at B1, and the leader records the azimuth and the distance.

The leader measures the azimuth and the distance from B1 to a second point on the right side of the minefield/munition field (facing the enemy). A marker is placed at this point and recorded as A1.

The leader measures the distance and the azimuth from A1 to the location of the first mine in that row and records the information.

The distance (or spacing) from the end row marker to the first mine is the spacing between all the mines in that row. After the location is recorded, the mine is emplaced, but it is not armed.

The leader measures the distance and the azimuth from the first mine to the second, and so on, until all the mines are emplaced and their locations are recorded. This procedure is repeated for the second row. As each mine is recorded, it is assigned a number to identify it in the minefield/munition field record. When the last mine location is recorded for a row, the distance and the azimuth are measured from that point to another arbitrary point, A2 or B2. A marker is placed here in the same manner as A1 and B1. Next, the distance and the azimuth from the RP to B2 and from B2 to A2 are measured and recorded.

When all the mines have been emplaced and recorded, the leader measures the distance and the azimuth between the RP and a permanent landmark that can be found on the map. He records the information on DA Form 1355-1-R. The landmark is used to help locate the minefield/munition field if it is transferred or unexpectedly abandoned. Finally, the tabular and identification blocks are completed.

Mines can be armed after recording is complete. The mines nearest the enemy are armed first, allowing soldiers to safely work their way back to the unit's position. Pins and clips can be buried 30 centimeters behind row markers, the RP, or any easily identifiable, accessible location. Note the location in the remarks section of DA Form 1355-1-R. The leader then reports the completion of the minefield/munition field to higher headquarters.

If the minefield/munition field is transferred to another unit, the receiving unit leader is briefed by the transferring unit leader. The receiving unit leader signs and dates the mines transferred block on the DA Form 1355-1-R. When the minefield/munition field is removed, the form is destroyed. If the minefield/munition field is abandoned unexpectedly, the DA Form 1355-1-R must be forwarded to higher headquarters.

#### NUISANCE MINEFIELD

It is unnecessary to record the precise location of individual nuisance mines that are laid in a pattern. Recording the position of a minefield/munition field that is laid in a pattern (either a standard pattern or one adopted for the situation) is easy and quick. However, the number of mines to be laid on site may make it impracticable or undesirable to lay mines in a pattern. In this case, they may be laid individually and their positions accurately recorded.

Figure 8-6a and Figure 8-6b provide an example of a completed nuisance minefield/munition field record.

### SCATTERABLE MINEFIELD/MUNITION FIELD REPORTING AND RECORDING

The speed and responsiveness of SCATMINE employment require accurate, uniform, and timely reports. All known information on scatterable minefields/munition fields is simply and rapidly reported to all affected units. Although SCATMINES have SD capability, they are still recorded; and the information is disseminated to prevent casualties to friendly forces.

Since the locations of individual SCATMINEs are unknown, they cannot be recorded in detail. For most systems, a safety zone is calculated from one or more aim points. For example, a RAAM minefield/munition field is recorded based on the target location (the grid coordinates given to the firing battery). The size of the minefield/munition field depends on the number of rounds fired, the number of aim points, and the angle of fire. An artillery-delivered minefield/munition field is recorded by plotting it on a map, based on the aim point and the safety zone specified in the scatterable minefield/munition field report and record that was prepared by the emplacing unit. A ground-Volcano minefield/munition field can be recorded more accurately by plotting each of the minefield/munition field corner points rather than an aim point.

To facilitate reporting and recording of scatterable minefields/munition fields, a simple, uniform procedure is used. This procedure combines the report and the record into one document (Figure 8-7) that is applicable for all delivery systems.

Figure 8-7. Scatterable minefield/munition field report and record work sheet

In addition to the scatterable minefield/munition field report and record, the SCATMINWARN (a sample is shown in Figure 8-8) notifies effected units that SCATMINEs will be emplaced. These two reports are the only reports used with scatterable mines.

Figure 8-8. Sample SCATMINWARN

A completed scatterable minefield/munition field report and record for an ADAM/RAAM artillery mission is shown in Figure 8-9. Note that on line 6, only one grid coordinate is given. It is the aim point used when the mission was fired. Also note that the 500-meter distance from the aim point (line 15) designates a safety zone that is 1,000 by 1,000 meters.

Figure 8-9. Scatterable minefield/munition field report and record for an ADAM/RAAM artillery mission

A completed scatterable minefield/munition field report and record for a Flipper mission is shown in Figure 8-10. Note that four corner points have been designated on the Flipper example. Corner points can be directly determined for the Flipper minefield/munition field. Corner points provide a more accurate means of recording the minefield/munition field than estimating a safety zone from an aim point.

The SCATMINWARN provides affected units with the necessary warning to plan and execute their operations. The information is kept to a minimum to ensure rapid dissemination. The report may be sent orally, digitally, or hard copy. It is sent before or immediately after the mines have been emplaced. A completed SCATMINWARN for an artillery mission is shown in Figure 8-11.
