Which of the following is NOT a core value of the Royal Marines?

Precision is not considered a core value of the Royal Marines. The core values that define the ethos and conduct of Royal Marines personnel are Courage, Respect, and Discipline.

Courage reflects the determination and resolve to face challenges bravely, essential in combat and operational scenarios. Respect underlines the importance of treating others with dignity and valuing teamwork and collaboration among peers and subordinates. Discipline is critical as it instills a sense of order, self-control, and adherence to military regulations and standards, which is vital for maintaining operational effectiveness and safety within the unit.

While precision is certainly important in military operations—particularly in tasks like navigation, aiming, and executing plans—it is not classified as one of the foundational core values like the others mentioned. This distinction makes it clear that while all aspects contribute to overall military effectiveness, only certain principles are honored as core values guiding the conduct and identity of the Royal Marines.
