Explain briefly, the conduct of a 25-meter zero fireing exercise |
On the 25-meter zero range, the soldier applies the fundamentals while consistently aiming at the targets center mass. The soldier fires 2 seperate three-round shot groups and groups them. Based on the location of these groups, the soldier makes the appropriate sight adjustments. Then, the soldier fires two additional 3-round shot groups to confirm that the adjustments have aligned the sights with the center of the target and that the bullets are in the 4-centimeter circle. IF 5 OUT OF THE 6 ROUNDS FELL WITHIN THE 4- CENTIMETER CIRCLE, THE SOLDIER IS ZEROED and can be removed from the fireing line. If not, the soldier returns to the fireing line and makes sight adjustments. |
