Which of the following is a primary function of the Precision Guidance Kit (PGK)?

The Precision Guidance Kit (PGK) primarily serves to improve the accuracy of artillery rounds by converting standard projectiles into precision-guided munitions. This enhancement allows for a more accurate targeting capability, significantly reducing the Circular Error Probable (CEP) of the rounds. The PGK achieves this by utilizing GPS guidance and other technologies to ensure that the projectiles hit their intended targets with greater precision, thereby improving the overall effectiveness of artillery fire while minimizing collateral damage.

The focus on accuracy is critical in modern warfare, where precision strikes can make a significant difference in mission success and mission safety.
