What does the concept of "roll-on/roll-off" (RORO) mean?

The concept of "roll-on/roll-off" (RORO) refers specifically to a technique allowing vehicles to be driven directly onto and off of ships without the need for cranes or additional lifting equipment. This method is particularly advantageous in amphibious operations and shipping logistics, as it streamlines the loading and unloading process, enabling rapid deployment of vehicles and cargo. Using ramps, vehicles can easily roll on at the point of embarkation and roll off at the destination, which enhances operational efficiency and reduces the time required for amphibious operations.

In contrast to the other choices, which address different aspects of military operations or logistics, RORO uniquely highlights the process of vehicle mobility on maritime transport. The method is not related to air strike deployment, troop movement strategies, or systems for cargo transfer between ports, all of which deal with different logistical or operational considerations.
