Which principle relates to the importance of having backup plans for operational capabilities?

The principle emphasizing the importance of having backup plans for operational capabilities is centered around developing contingencies for dismissed capabilities. In military operations, the unpredictability of combat can lead to changes in the battlefield situation that may render original plans or capabilities less viable or even obsolete. By preparing contingency plans, military leaders can ensure that alternative strategies and resources are available to adapt to these changes, thereby preserving mission effectiveness and operational flexibility.

This principle embodies the idea that preparation is key to successful operations. It allows units to respond proactively to sudden shifts in dynamics, such as the loss of key equipment or personnel, changing enemy tactics, or unforeseen environmental factors. A robust set of backup plans enhances resilience and ensures that an operation can continue smoothly even when initial capabilities are compromised.

The other choices, while relevant to operational considerations, do not directly address the need for backup plans. Avoiding target overkill pertains to efficient resource utilization, destroying the greatest threat first focuses on prioritization in engagement, and preventing fratricide involves ensuring the safety of friendly forces during operations. None of them encapsulate the critical nature of having well-defined contingency plans for when primary capabilities are challenged or rendered ineffective.
