Calculation Of Leads

Once the required lead has been determined, the sniper should use the mil scale in the scope for precise holdoff. The mil scale can be mentally sectioned into l/4-mil increments for leads. The chosen point on the mil scale becomes the sniper's point of concentration just as the cross hairs are for stationary targets. The sniper concentrates on the lead point and fires the weapon when the target is at this point. The following formulas are used to determine moving target leads:

TIME OF FLIGHT X TARGET SPEED = LEAD.

Time of flight= flight time of the round in seconds.

Target speed = speed the target is moving in fps.

Lead = distance aiming point must be placed ahead of movement in feet.

Average speed of a man during—

Slow patrol = 1 fps/0.8 mph

Fast patrol = 2 fps/1.3 mph

To convert leads in feet to meters:

LEAD IN FEET X 0,3048 = METERS

To convert leads in meters to mils:

LEAD IN METERS x 1,000 = MIL LEAD

RANGE TO TARGET
