On approval, they are to engage enemy commanders and radio operators with long range fire. They will then fall back into positions within the company perimeter. They know that the enemy forces will be moving in a tactical formation that may have a depth of 150-200 meters. Using a point blank zero for a kill zone diameter of 24 allows them to engage to a range of 550 meters without range determination. They can use the map to get a rough range as to when they can engage.
Mil relation is accurate enough to support point blank zero fire.
All they have to do is confirm that the enemy is higher than 2 MILS from the head to their crotch and they are within 500 meters. As the enemy moves in range. A coordinated fire between the companies 6 snipers drops 4 possible officers and 2 radio operators. The snipers pick out 4 more targets than move into the company perimeter. Once in the perimeter they prepare to engage priority targets in support of the main defense.
