Which principle of joint operations involves using available resources to achieve the greatest effect?

The principle of joint operations that involves using available resources to achieve the greatest effect is Economy of Force. This principle emphasizes the efficient allocation and use of military resources to achieve the desired objectives while minimizing unnecessary expenditure of assets.

In practical terms, Economy of Force involves prioritizing the amount and type of forces needed to achieve a specific goal, allowing commanders to allocate personnel, equipment, and support in a way that maximizes their overall impact. Effective use of this principle can lead to a strategic advantage, enabling forces to work smarter rather than simply relying on overwhelming numbers.

This principle helps to ensure that limited resources are utilized where they can have the most significant impact, aligning closely with the overarching goals of the mission. It supports the overall strategy by ensuring that forces are not wasted on tasks that do not contribute to the critical objectives of the operation.
