Which of the following is NOT one of the 4 C's of the UXO Battle Drill?

The correct answer, "comply," is not one of the 4 C's of the UXO Battle Drill. The 4 C's typically include classify, cordon, control, and communicate, which are critical steps in the management and response to unexploded ordnance scenarios.

Each of the correct elements plays a pivotal role in ensuring the safety and effectiveness of UXO operations. Classifying involves identifying the type of ordnance and assessing the potential risks and necessary responses. Cordon refers to the action of establishing a safe perimeter around the UXO site to protect personnel and limit access. Control is about managing the situation effectively, including securing the area and operational command over the response.

In contrast, "comply" does not fall into this framework, which focuses on specific tactical actions rather than compliance with protocols or regulations, making it the outlier in this context. This distinction is essential for understanding how to approach and address UXO incidents in a systematic and safe manner.
