The Observer Target (OT) Factor is used to determine which of the following?

The Observer Target (OT) Factor is used to determine which of the following?

• A. Left/Right deviation correction
• B. Elevation adjustment
• C. Range to target
• D. Time to impact

Answer: (A)

The main idea is about horizontal aiming, i.e., azimuth corrections. The OT (Observer-Target) Factor is used to determine how much left or right adjustment is needed to bring the fire onto the target after you observe where the impact fell relative to the target. In practice, when you see the impact off to one side, you translate that lateral deviation into a deflection correction to apply on the next shot, using the OT factor as the guide for how many mils (or the units used) to adjust in the left/right direction. This is distinct from range or elevation concerns, which involve calculating how far away the target is or how high to aim, and from time-to-impact, which is a ballistic timing calculation. For example, if the impact is observed to the left of the target, you apply a correction to the right, scaled by the OT factor, to steer subsequent rounds toward the target.
