What common combat task requires endurance and rapid movement?

The task that emphasizes endurance and rapid movement is marching under load. This activity involves moving quickly and efficiently while carrying equipment, which can weigh significantly. It is essential for combat readiness, as soldiers often need to traverse long distances with their gear to reach objectives, execute missions, or reposition during engagements.

Marching under load not only tests physical endurance and stamina but also replicates real-life conditions faced in combat situations where quick mobility is crucial. Endurance is cultivated through such tasks, enabling soldiers to maintain their performance over extended periods while managing the physical demands of their equipment.

The other options, while they do involve elements of endurance or preparation, do not directly connect to the dual requirement of both endurance and rapid movement in the same way.
