10–11. Improved conventional munitions a. Firing conditions. (1) The firing of live ICM projectiles and dropping of aircraft-delivered live sub-munitions on Army ranges in training are currently prohibited. (2) For the Marine Corps, the firing of dual-purpose improved conventional munitions is authorized in accordance with MCO P8011.4 and current MCBul 8011. Local range SOPs will dictate the specific conditions under which dual- purpose improved conventional munitions may be employed in training. (3) ICM projectiles will not be fired over the heads of troops in training exercises. (4) When ICM carriers fail to function and impact on hard surfaces, up range and lateral ricochets of up to 500 m may occur. b. Surface danger zone. (1) Requirements for field artillery cannon fired ICM are given in figures 10–1. Conventional ballistic tabular firing table data for the particular caliber projectile and weapon system combination will be used to determine maximum range when firing ICM projectiles. (See table 10–6). (2) The impact area should be relatively flat and free from heavy vegetation. (3) Danger Areas A and B will be observed for all firings of ICM projectiles. The data necessary to determine each of these are in table 10–7. (4) The special design of ICM projectiles subjects them to the effects of wind velocity more than standard conventional projectiles. Sub-missile drift factors listed in table 10–8 may be added to or subtracted from the basic trajectory distances presented in respective ballistic tabular firing tables. For example, if the wind is blowing at 50 knots from the gun position toward the target and the gun is being fired at 600 mil (33.75 degrees), the maximum range from the firing table will be increased by 150 m. If the wind is coming perpendicular (left to right) to the GTL, the right deflection will be increased 160 m and the left deflection will be decreased 160 m.
