Which military principle emphasizes the importance of concealing plans and intentions?

The principle that emphasizes the importance of concealing plans and intentions is security. This principle is fundamental in military operations as it involves protecting information that could be advantageous to the enemy. Security ensures that friendly forces maintain operational integrity by minimizing the risk of enemy forces anticipating actions or movements. By safeguarding plans and operations, commanders can retain the element of surprise and create opportunities for success on the battlefield.

In military doctrine, security extends beyond just the physical protection of forces; it encompasses information security, operational security, and personal security, all of which help to prevent the enemy from gaining insight into friendly capabilities and intentions. Therefore, prioritizing security allows military leaders to maintain an advantage and execute their strategies effectively.
