g. The 25 degree angle for Area A must be increased to 70 degrees when firing HE ammunition at ranges equal to or less than 600 m for 60mm mortars; 940 m for 81mm mortars; and 1500 m for 120mm mortars. Only the personnel required to fire the mortar system are authorized to be within this area. h. Only the mortar crew are authorized to be in Area A. Table 9–1 Mortar surface danger zone criteria (in meters) 1, 2, 3 Caliber Area A Area B 60mm 250 300 81mm 400 400 120mm 600 600 Notes: 1 Quadrant elevation limits must be modified to take into account the distance to the minimum and maximum limits of the impact area. After registration, corrections must be applied to the deflection quadrant elevation limits. 2 Dimensions of Areas A and B may be reduced by 50 percent when firing illumination cartridges. 3 Cartridges without HE filler (for example, M880, M931) do not require Areas A and B.
