When carrying out command-assigned duties, a petty officer can direct the actions of

Both Junior and Senior personnel

Explanation:

A petty officer is pretty much one of the lowest rank in the Navy, but they are typically equal to a corporal or sergeant in other branches of military. However command-assigned duties provides a petty officer the power to direct the actions of both junior and senior personnel without been punished. For example, it is known that only officers and commanding officers can assign an EMI to be done after working hours. Nonetheless, if this is delegated to petty officers in connecting with their responsibilities, then they can perform this task.
