Which of these actions exemplifies the principle of "surprise" in air assault tactics?

The principle of "surprise" in air assault tactics is exemplified by unexpected timing and location of the assault. This approach catches the enemy off guard, disrupting their ability to respond effectively. By choosing when and where to launch an attack without prior warning, forces can exploit vulnerabilities and achieve tactical advantages.

In tactical operations, the element of surprise can greatly enhance the likelihood of success, as it diminishes the enemy's preparedness and complicates their defensive efforts. This method not only creates confusion among enemy ranks but also allows friendly forces to seize the initiative and dictate the flow of the engagement.

Communicating plans well in advance and establishing a fixed schedule for all operations are contrary to the principle of surprise, as they give the enemy an opportunity to prepare and adjust their defenses. Similarly, rehearsing every aspect of the mission multiple times may lead to predictability, reducing the likelihood of achieving the desired element of surprise during the operation.
