What is one of the key features of the Restricted Maneuvering Doctrine?

The key feature of the Restricted Maneuvering Doctrine is indeed the limitation of tactical flexibility. This doctrine is designed to ensure safe operation in certain high-risk conditions, particularly when the threat of an accident or attack is present. By restricting maneuverability, it aims to minimize the potential for collisions or other incidents that could compromise the safety of the vessel and crew.

In scenarios where the doctrine is in effect, the flexibility to execute rapid maneuvers is limited to prioritize caution and safety, often at the expense of operational maneuvers that might be strategically advantageous. This is particularly relevant in situations where navigating through congested waters or while engaged in certain missions and operations where the risk of attack or accidents is heightened.

The other options, such as maintaining full speed, controlling electrical systems, or maximizing crew assignments, do not align with the central premise of the doctrine. They focus more on operational enhancements or logistics rather than prioritizing safety through constrained movement, which is the essence of the Restricted Maneuvering Doctrine.
