Which of the following is NOT a characteristic of ACE?

The correct choice is that operational capability is not a characteristic of ACE (Agile Combat Employment). ACE focuses on increasing the resilience and operational effectiveness of air operations in contested environments. The other concepts emphasize attributes that are crucial to maintaining effective operations.

Enduring efficiency highlights the necessity for streamlined processes and resource management to ensure that operations can continue effectively over time without unnecessary waste. It underscores the goal of maintaining operational readiness with maximum efficiency.

Minimal training implementation refers to achieving operational capability with less extensive training frameworks, enabling quicker deployment and adaptability in dynamic scenarios. This is vital in ACE, as it allows forces to respond rapidly when needed.

Special mission focus pertains to the ability to tailor operations to specific, critical missions, ensuring that airpower can be effectively projected and sustained in various contexts. This aligns with the overarching strategy of ensuring that forces can be employed in a manner uniquely suited to the operational environment.

Operational capability, while fundamental to any military strategy, is not specifically a defining characteristic of ACE itself; rather, it is an outcome of effectively implementing the principles that ACE stands for.
