Which of the following is a type of Movement Order?

The correct answer is Operation Order. An Operation Order is a comprehensive directive issued by a commander that outlines the mission, tasks, and coordination necessary to achieve objectives during a specific operation. Movement Orders are key components of an Operation Order as they provide detailed instructions on the execution of movement and maneuvering troops and assets to carry out the mission successfully.

While Warning Orders, Fragmentary Orders, and Service Support Orders play essential roles in military operations, they serve different purposes. A Warning Order is typically an initial communication that alerts units to an impending operation and prepares them for further planning. A Fragmentary Order communicates changes or updates to an existing Operation Order. Service Support Orders focus on logistics, supply, and administrative functions required to sustain the operation but do not specifically address movement instructions.

Therefore, Operation Order is the most appropriate choice as it inherently includes elements of movement planning, thereby making it a type of Movement Order.
