All military authority exists under and is administered by the chain of command. This essentially describes to whom you are responsible and who has authority to issues orders or directives to you. It also delineates whom you should contact with questions, problems or applications for approval.
Your first point of contact is your local ROIC who, if unable to answer your query, will forward the question/issue to UTW1 (see Contacts)
Applications should be forwarded directly to UTW1 who will then either approve or, where a higher authority is required, forward to your commanding officer for approval.
