Figure 7-39. Bullet trajectory comparison.

As the chart shows, the hold-off at 400 meters is about half the height of the standard E-type silhouette; therefore, to hold-off at 400 meters you must aim half the height of the target over the target to hit it. The drop at 500 meters is considerably larger, so holding off will not be practical. The shooter will have to adjust his rear elevation knob to get the proper aim point for that distance.

(2) Windage. When firing during windy conditions and there is no time to make sight adjustments, the SDM must use hold- off to adjust for windage (Figure 7-40, page 7-56). When holding off, the SDM aims into the wind. If the wind is moving from the right to left, his point of aim is to the right. If the wind is moving from left to right, his point of aim is to the left. Constant practice in wind estimation can bring about proficiency in making sight adjustments or learning to apply hold-off correctly. If the SDM misses the target and the point of impact of the round is observed, he notes the lateral distance of his error and re-fires, holding off that distance in the opposite direction. Table 7-10, page 7-56, shows calculated adjusted aiming points based on wind speed.

The firers can demonstrate that they understand holding off by using an M15 sighting device. The firer aligns the sights on the silhouette on the proper adjusted aiming point. Once the firer has an understanding of elevation and windage hold-off, he is able to begin the live-fire training exercise (Table 7-11). The firer will be given 20 rounds in which to engage 20 targets at ranges from 100 to 500 meters using elevation and windage hold-off.

NOTES: 1. Ensure weapon is zeroed prior to training.

2. Ensure soldier knows how to adjust for wind and gravity.

3. Ensure soldier can manipulate the rear sight for different ranges.

e. PHASE V—Field Fire 100 to 500 Meters. Field fire will consist of both a Record Fire I and a Record Fire II course. The field-fire events (Table 7-12) will test the individual's marksmanship, range estimation, and target detection skills. Each Record Fire course will have targets at ranges from 100 to 500 meters. Each firer will engage a total of 20 targets with 20 rounds. Soldiers will fire the table using both the foxhole supported or prone supported position (sandbags) and the prone unsupported firing position. An individual must attain a total of 14 hits out of 20 targets to pass. The Record Fire I course requires the individual to use mechanical elevation and windage adjustments. The Record Fire II course requires the individual to use elevation and windage hold-off (adjusted aiming points). If the SDM is issued an optic, the Record Fire II course will substitute use of that optic instead of using adjusted aiming points.

NOTES: 1. Ensure weapon is zeroed prior to training.

2. Ensure soldier is able to assume a steady firing position.

3. Ensure soldier is able to consistently apply the fundamentals of marksmanship.

4. Ensure soldier knows how to adjust for wind and gravity.

5. Ensure soldier can manipulate the rear sight for different ranges.

NOTE: The firer must engage 14 out of 20 targets at 100 to 500 meters during each field-fire exercise. (See Appendix B for a reproducible scorecard.)

f. Certification. Once the firer has successfully completed the SDM program, he is designated as an SDM and will be able to perform all duties and responsibilities set forth by these guidelines.

NOTE: The skills of the SDM are highly perishable and sustainment training should be conducted to ensure retention of the skills. At a minimum, sustainment training should be conducted semiannually.
