Which of the following is NOT one of the 5 Cs?

The correct answer is that "Contain" is not one of the 5 Cs. The 5 Cs, which are crucial for effective gunnery in the USMC, are concepts that guide Marines in both planning and executing operations involving machine guns. Each of the 5 Cs contributes to successful engagement and fire control during a mission.

The 5 Cs typically include "Call," which refers to effectively communicating essential information about targets and fire; "Control," which emphasizes managing the engagement to ensure accuracy and effectiveness; and "Cordone," which may represent the principles surrounding the securing of areas of operation. However, “Contain” does not align with the established terminology of the 5 Cs in this context. Understanding these terms is essential for Marines to effectively coordinate their actions and maintain a high level of operational readiness.
