Final answer:
In the military, a flag officer may delegate the authority to sign reports withdrawing a recommendation for enlisted advancement to an officer of a certain rank or above.
Step-by-step explanation:
In the military, a Co (Commanding Officer) must sign any report that withdraws a recommendation for enlisted advancement after advancement authorization has been received. However, a flag officer has the authority to delegate this responsibility to an officer of a certain rank or above.
The rank to which a flag officer can delegate this authority is usually the rank of a junior officer or higher, depending on the specific military branch and policies. For example, in the U.S. Navy, a flag officer may delegate this authority to an officer with the rank of Lieutenant Commander or above.
It is important to note that the specific rank or grade to which a flag officer can delegate this authority may vary within different military organizations.
