Which commander retains overall responsibility for mission accomplishment?

The correct choice is the OTC, or Officer in Tactical Command. This individual holds the overall responsibility for mission accomplishment within a given operational context. The OTC is equipped with the authority and situational awareness to direct forces, make strategic decisions, and adapt to changing circumstances during the execution of the mission. This position is crucial in military operations, as it ensures that there is a single point of accountability and leadership, which is essential for achieving objectives effectively.

In operational frameworks, the roles of other commanders such as the Functional Warfare Commander, CWC (Commander, Warfare Commander), and PWC (Platform Warfare Commander) are significant and aligned with specialized areas and specific components of warfare. However, these roles do not carry the overarching responsibility for the overall success of the mission in the same way that the OTC does. The OTC integrates multiple strategies and resources, managing the command structure to align all operational efforts toward a common goal, thereby ensuring cohesive mission execution.
