Which characteristic is essential for the design of MK-V Special Operations Crafts?

The essential characteristic for the design of MK-V Special Operations Crafts is high speed and mobility for swift insertion. These crafts are specifically designed to quickly transport special operations forces to their operational areas, enabling a rapid deployment that is crucial in time-sensitive missions. The high speed allows them to navigate through various maritime environments effectively, helping to minimize the risk of detection and increasing the chances of mission success.

While other attributes may also be beneficial for certain missions, such as the ability to operate in shallow waters or the capability to carry equipment, the primary focus for MK-V crafts is to ensure that operators can be inserted and extracted quickly and efficiently. This focus on speed and mobility is particularly important in special operations, where timing often plays a critical role in achieving mission objectives.
