What kind of approach does the military generally use for wartime movement?

The military typically relies on contingency planning for wartime movement due to its flexibility and adaptability to various unpredictable scenarios. Contingency planning allows for the creation of detailed response strategies that can be executed quickly in the face of changing circumstances. This kind of planning involves forecasting potential threats, analyzing available resources, and formulating multiple courses of action. By doing so, military operations can be tailored to respond effectively to unexpected challenges, ensuring that objectives can still be met, regardless of the situational dynamics on the ground.

The other options, while relevant in different contexts, do not capture the essence of the military's approach to movement during wartime as effectively. Standard procedures might not account for unforeseen conditions, mass deployment focuses more on volume rather than strategic elements, and strategic maneuvers are typically tactical in nature rather than encompassing the broader logistical and operational planning necessary for wartime movement. Thus, contingency planning stands out as the most comprehensive and responsive method in this context.
