What is the formula for calculating the vertical interval?

• A. TGT ALT - UNIT ALT
• B. UNIT ALT - TGT ALT
• C. TGT ALT + UNIT ALT
• D. TGT ALT / UNIT ALT

Answer: (A)

The formula for calculating the vertical interval is based on the difference in elevation between the target and the unit's altitude. In this context, the vertical interval is determined by subtracting the unit's altitude from the target altitude. The target altitude represents the height at which the target is located, while the unit altitude shows the elevation of the observing unit. Using the formula TGT ALT - UNIT ALT allows for a straightforward calculation of the vertical distance that must be accounted for in artillery and fire control operations. This is crucial for achieving accurate targeting, as it helps to ensure that the projectile will reach the intended point of impact, taking into consideration the elevation differences between where the fire is being commanded from and where the target is located. The other options do not correctly represent the relationship needed to calculate the vertical interval. For example, subtracting the target altitude from the unit altitude flips the intended calculation, and addition or division does not apply to this context of measuring vertical space. Properly knowing how to compute the vertical interval directly impacts fire accuracy and effectiveness in operational scenarios.
