Overhead fire a. Overhead fire of unprotected personnel located in Area D is authorized during training provided certified ammunition for overhead fire (projectile, propellant/tailcharge, and fuze) is used. (For the Marine Corps’ EFSS M327 mortar, only the M1101 HE, M1103 WP, and M1105 Illumination projectiles with M237 tailcharge are authorized for overhead fire.) Senior commanders (Army)/installation commanders (Marine Corps) may authorize nonparticipating personnel access to Area D during indirect field artillery and EFSS 120mm (rifled) mortar firing. When public highways pass through Area D, coordination with appropriate government officials (Federal, State, and/or local) and/or land owner(s) is required. When public roadways and railways pass through Area D, the following precautions apply: (1) Projectile trajectories must clear unprotected personnel or objects by at least 5 m plus two forks. If the minimum range line (arc) is greater than the distance to the near edge of the target area, use the computed minimum range line (arc) for the near edge of the target area. (2) Unless personnel are provided cover designed to withstand a direct hit, the minimum arming time of the proximity (VT) fuze establishes the near edge of the impact area. The minimum arming time of the proximity (VT) fuze will be the time set on the fuze corresponding to the range to the near limit of the impact area or computed minimum range line, whichever is greater, plus 5.5 seconds. (3) Forward movement of personnel within Area D requires that the SDZ advance according to the distance and direction of the personnel. If proximity or VT fuzes with adjustable arming times are used, forward movement of personnel is possible. VT fuze time settings will correspond to the range to the near limit of the impact area plus 5.5 seconds. (4) Warnings that field artillery projectiles may be fired at any time of the day will be posted on public roadways approved for overhead fire that passes through an installation or community. b. If rocket assisted projectiles will be fired over the heads of unprotected troops during training exercises, ensure compliance with provisions of paragraph 10–3g. 10–7. Expeditionary Fire Support System M327 120mm rifled towed mortar For the Marine Corps, the EFSS M327 120mm rifled towed mortar uses an SDZ similar to that of an artillery weapon system when firing spin-stabilized ammunition. Table 10–4 and figure 10–1 will be used to construct the SDZ for the EFSS M327 120mm rifled towed mortar. When firing fin-stabilized ammunition from the EFSS M327 120mm rifled towed mortar, use the SDZ in figure 9–1 and the data from table 9–1.
