What is the principle of surprise?

• A. Deliver operations with maximum speed, regardless of planning.
• B. Deliberately reveal intentions to confuse the enemy.
• C. Exploit enemy strength by frontal assault.
• D. Deliver operations in a way that the enemy does not anticipate.

Answer: (D)

The principle of surprise is about delivering operations in a way the enemy does not anticipate, catching them off guard and disrupting their decision cycle. When actions occur where the foe isn’t expecting them, their timing, coordination, and ability to react are thrown off, creating opportunities for success that would be unavailable if the plan were anticipated. Achieving surprise often involves concealment of intentions, unconventional timing or methods, and exploiting a window when the enemy is unprepared.

This aligns with striking when the enemy is not ready rather than forcing a fast attack, telegraphing plans, or choosing a direct, heavily resisted approach. Speed alone can betray the plan if the enemy can foresee it; revealing intentions eliminates the element of surprise; and a frontal assault on a prepared foe simply confirms expectations rather than breaking them.
