Which guideline emphasizes the importance of acting swiftly in combat decisions?

The emphasis on speed in combat decisions is crucial because in the dynamic and unpredictable environment of warfare, the ability to respond quickly can significantly impact the outcome of engagements. Swift actions allow individual Marines and units to seize the initiative, outmaneuver opponents, and take advantage of fleeting opportunities.

Timely decision-making minimizes the risk of becoming a target or missing strategic advantages, which can be vital in ensuring mission success. Quick responses can also help to maintain cohesion within units and ensure that all members are aligned and moving towards a common goal without hesitation.

While other guidelines, such as being practical and accepting risk, are important in the overall decision-making process, they inherently underscore the necessity of speed in execution. Speed is a distinct guideline that prioritizes the urgency of action in combat situations, where delaying a decision can lead to dire consequences.
