Which of the following is NOT a characteristic of defense?

In defensive operations, a full frontal assault is not a characteristic because the nature of defense typically involves using terrain, strong points, and strategic positioning to protect against enemy advances. Defensive tactics prioritize minimizing exposure to enemy fire, leveraging cover and concealment, and focusing on creating layered defenses rather than engaging the enemy through direct frontal assaults, which can lead to high casualties without effectively using the defensive position.

On the other hand, concentration of forces allows for a more formidable defense at critical points, operational depth ensures that there are multiple layers of defense to slow an enemy advance, and flexibility allows units to adapt their defensive posture in response to changing battlefield conditions. These characteristics are essential in creating an effective defensive strategy that can withstand and repel enemy attacks.
