Final answer:
In a military context, when an attachment is given, sufficient orders and instructions must be provided to the attached units. This ensures understanding of their roles and how they fit into the overall mission, contributing to operational effectiveness and unity of effort.
Step-by-step explanation:
When an attachment is given in a military context, which requires the integration of additional units into existing formations, sufficient orders and instructions must be provided to cover that part of the operation. These are meant to ensure that the attached units understand their roles, responsibilities, and how they fit into the overall mission. Therefore, the correct answer is D) Sufficient orders and instructions.
Effective orders will typically include the purpose of the attachment, the tasks to be accomplished, the allocated resources, and any specific coordination or integration measures that are needed. Moreover, clear instructions provide the attached unit with the necessary information on command relationships, logistics, communication protocols, and other essential operational details. These components are crucial for maintaining operational effectiveness and unity of effort within a larger military operation.
