Chapter 6 6-6 ATP 3-09.30 28 September 2017 ANTIPERSONNEL ROUND 6-23. The antipersonnel improved conventional munitions (APICM) (see figure 6-1) are most effective against unwarned, exposed personnel. When the fuze functions, an expelling charge forces the grenades out through the base of the projectile. Small vanes on each grenade flip upward, arming the grenade and stabilizing it in flight. When the striker plate on the base of the grenade contacts the ground, the grenade is hurled upward four to six feet and detonates. M449 APICM dispersion pattern is generally elliptical in shape. The dispersion pattern covers approximately 100 meters by 60 meters. APICM is no longer manufactured but is still held in war reserve. Figure 6-1. APICM grenades DUAL PURPOSE ROUND 6-24. DPICM grenades (see figure 6-2) are most effective against lightly armored or thin skinned vehicles. After the grenade is ejected, a ribbon streamer arms and stabilizes it. On impact, a shaped charge that can pierce light armor is detonated. The surrounding steel case fragments are very effective against personnel as well. 6-25. M438A1 DPICM dispersion generally changes shape from elliptical at minimum ranges and lower charges to almost circular at maximum ranges. At minimum ranges, the dimensions are approximately 50 meters by 100 meters. At maximum ranges, they are approximately 100 meters by 120 meters. Figure 6-2. 155-mm DPICM grenade
