How much lead is built into the left lead reticle?

• A. 6 degrees
• B. 10 degrees
• C. 12 degrees
• D. 8 degrees

Answer: (B)

Leading a moving target means aiming where the target will be, not where it is right now. The left lead reticle encodes a fixed angular offset to help you apply that lead quickly, based on the Stinger’s time-of-flight and typical target motion. That built-in offset is 10 degrees, so placing the target within the left lead reticle puts your aim ahead by about 10 degrees to compensate for the target’s lateral movement and the missile’s travel time. This value strikes a practical balance for common engagement speeds and ranges in training, giving reliable hit probability without extra calculation. Smaller or larger offsets would either undershoot or overshoot under standard conditions, which is why 10 degrees is the correct built-in lead.
