What are the five requirements for achieving accurate first-round fire for effect?

Achieving accurate first-round fire for effect is a critical objective in fire support operations, as it enhances the effectiveness of artillery and maximizes the potential for mission success while minimizing the risk of collateral damage.

The requirement for accurate target location and size is fundamental because it ensures that the munitions land on the intended target with precision. If the target location is incorrect or the estimated size of the target is inaccurate, the chances of missing the target or causing unintended damage increase significantly. The accuracy of the target's coordinates allows the firing unit to apply its fires with confidence, thereby ensuring that the desired effects are achieved immediately and effectively.

Successful fire support also relies on complementary requirements, such as knowing the location of the firing unit and having accurate information on the weapon and ammunition being used, as well as pertinent meteorological data. However, these factors become less impactful if the target location and size are not precisely known. Hence, accurate target location and size is the most crucial requirement for achieving the desired first-round fire for effect.
