To determine the OT factor, the observer must divide distance to the target by what value?

To determine the OT factor, the observer must divide distance to the target by what value?

• A. 1000
• B. 500
• C. 200
• D. 10

Answer: (A)

Dividing the distance to the target by 1000 converts meters into thousands of meters (i.e., kilometers), which is the scale used for the OT factor. This creates a compact, standardized number you can use in spotting and ballistic calculations. For example, 2,800 meters becomes an OT factor of 2.8, and 7,500 meters becomes 7.5. Using any other divisor would yield a different, non-standard scale and wouldn’t match how the OT factor is defined and applied in practice.
