Special Munitions 28 September 2017 ATP 3-09.30 6-9 CHARACTERISTICS OF FIELD ARTILLERY SCATTERABLE MINES 6-39. In the field artillery, a scatterable mine refers to the two types of field artillery delivered scatterable mines , the remote antiarmor mine system and area denial artillery munitions See ATP 3-34.22 and TM 43- 0001-28 for additional information on the RAAMS and ADAM. 6-40. The planning associated with obstacles is the responsibility of the engineer cell. The relationship between the engineer and fires cells is crucial, as these minefields are delivered by field artillery assets. RAAMS PROJECTILES 6-41. Use RAAMS projectiles to delay or disrupt adversary formations and maneuver or to reinforce existing obstacles. A 155-mm howitzer fires the RAAMS projectile which base ejects antiarmor mines (see figure 6- 3) over the target area. After a short delay to allow for mine freefall, impact, and roll, the magnetically fuzed mines arm themselves. Upon arming field artillery delivered scatterable mines perform a self-test. All mines that fail the self-test SD immediately. Any metallic object such as a tank or self-propelled vehicle passing over the armed mines will cause the mines to detonate. 20 percent of RAAMS mines have antidisturbance features that cause the mines to detonate if they are moved or picked up. If not detonated, RAAMS mines begin to self-destruct after 80 percent of the factory set SD time elapses. The probability of a live mine existing past its stated SD time is 0.001. The SD time for the munitions are: The M718 and M718A1 projectiles have a long SD time (48 hours). The M741 and M741A1 projectiles have a short SD time (4 hours). Note. Most RAAMS (and ADAM) mines arm in two minutes. Production improved mines (type designated A1 arm in 45 seconds) Figure 6-3. RAAMS mine ADAM PROJECTILES 6-42. Use ADAM mines against personnel, dismounted personnel in an armored attack, or on existing antitank obstacles to hinder dismounted breaching. When employed against an adversary that has a dismounted breaching capability, deliver ADAM mines directly on top of a RAAMS minefield. ADAM rounds are always the last rounds fired when used in conjunction with RAAMS or other munitions. This prevents the accidental destruction of the ADAM munitions by other munitions. 6-43. A 155-mm howitzer fires the ADAM projectile which base ejects 36 antipersonnel mines (see figure 6-4 see on page 6-10) over the target area. When an ADAM mine comes to rest on the ground, several tripwire sensors are deployed out to a maximum distance of 20 feet. When a sensor is disturbed or tripped, it propels a small ball like munition two to eight feet upward. The munition detonates and scatters approximately 600 1.5 grain steel fragments in all directions. If not detonated, the ADAM mines will begin to SD after 80 percent of the factory set SD time elapses. The destruct times for the munitions are:
