Which characteristic is NOT one of the four listed for offensive operations?

In the context of offensive operations, the characteristics that define the nature and execution of these operations emphasize the importance of elements like surprise, audacity, and concentration. Surprise is crucial as it allows forces to catch the enemy off guard, leading to greater tactical advantages. Audacity refers to the boldness and decisiveness in planning and executing operations, while concentration focuses on the massing of combat power at the decisive point to achieve maximum effect.

On the other hand, while progress might seem relevant, it is not classified as one of the core characteristics of offensive operations. The characteristics of an offensive operation are primarily about the impact and approach to engagement rather than the broader objective of advancement or progress itself. Hence, 'progress' does not align with the specific tactical principles laid out for successful offensive operations.
