Who is NOT authorized to issue a medical clearance for a Marine who answers YES in section B of the RFW?

The authority to issue a medical clearance for a Marine who indicates a "YES" response in section B of the Risk Factor Worksheet (RFW) typically lies with medical officers, health care provider assistants, or physical therapists, as they have the necessary training and credentials to assess and determine fitness for duty based on medical guidelines and requirements.

Independent duty corpsmen, while trained to provide a range of medical care, do not usually hold the same level of authority as those other professionals to issue medical clearances in this context. The medical clearance process is designed to ensure safety and compliance with military health standards, requiring oversight by licensed healthcare professionals with the appropriate authority. In this scenario, the other choices listed are recognized professionals able to evaluate and grant medical clearances, which distinguishes independent duty corpsmen from those roles.
