Special Munitions 28 September 2017 ATP 3-09.30 6-15 TWO GUN ILLUMINATION 6-62. Use the two gun illumination pattern when an area requires more illumination than can be furnished by one gun illumination. In this pattern, two rounds burst simultaneously in the target area. To obtain this pattern, the observer calls for ILLUMINATION TWO GUNS. Two Gun Illumination Range Spread 6-63. Use this pattern (see figure 6-7) d illumination causes fewer shadows than illumination that is concentrated in one place. To obtain a range spread pattern, the observer calls for ILLUMINATION RANGE SPREAD. The FDC centers the spread over target location sent by the observer. See Table 6-13 for distances between bursts. Figure 6-7. Illumination range spread Two Gun Illumination Lateral Spread 6-64. Use this pattern (see figure 6-8 on page 6-16) when the area to be illuminated has greater width than depth. To obtain a lateral spread pattern, the observer calls for ILLUMINATION LATERAL SPREAD. The FDC centers the spread over target location sent by the observer and orients the spread perpendicular to the observer-target line. Distances between bursts are the same as those for a range spread pattern (see table 6- 13 on page 6-14).
