Special Munitions 28 September 2017 ATP 3-09.30 6-5 6-20. The M31/M31A1 GMLRS warhead is a 200 pound class scored steel case fragmentation high explosive warhead. Maximum range exceeds 70 kilometers. In addition to providing point detonating, delay, and proximity fuzing options, a vertical attack trajectory option exists to enable employment in urban environments and in maximizing effectiveness of delay and proximity fuze modes. The proximity fuze mode causes warhead detonation at approximately 7 meters above the target, the point detonating mode causes detonation upon impact, and the delay mode causes detonation as the nose cone penetrates about one meter into the ground, this places the explosive filled canister partially below the surface of the ground. SAMPLE GLMRS MISSION 6-21. Request GMLRS in a standard call for fire just like any other specific ammunition. Table 6-5 provides a sample GMLRS call for fire. Planned GMLRS missions currently require a mensurated target location. Table 6-5. Fire for effect with GLMRS unitary Observer Fire Direction Center P51 THIS IS P87, FIRE FOR EFFECT, OVER.

Improved conventional munitions are base ejection projectiles with a mechanical time fuze and a body assembly containing a number of sub munitions (grenades). Centrifugal force dispenses the grenades radially from the projectile line of flight. The size and shape of the sub munitions dispersion patterns are not constant and change over range. In addition, the concentration of sub munitions is not uniform over the entire surface area. There is a noticeable decrease of sub munitions in the center of the dispersion pattern. There are two types of ICM rounds: the antipersonnel round and the dual purpose round. Table 6-6 shows the number of grenades in each ICM round. Table 6-6.
