Who is higher rank master chief or senior chief?

Answer 1

pretty much all officers. Master Chief is the highest rank possible for infantry and is not technically an officer so technically petty officer- general has rank on him

FIrst the above answer contains incorrect information. The Ranks of Master Chief and Senior Chief are not used by the infantry which is the Army and Marines.

The US Navy and US Coast Guard use the same rank structure and rank titles for their Officer Corps and Enlisted.

A MCPO or Master Chief Petty Officer is the highest rank an enlisted member of the Navy or Coast Guard can earn. Just below a MCPO is a SCPO or Senior Chief Petty Officer. Any Petty Officer is refered to as a Non Commissioned Officer (Non-Com). Before the new uniforms came out Chief Petty Officers (Called Chief) , Senior Chiefs (Called Senior) and Master Chiefs (Called Masser Chief) all wore the same uniform as warrant officers and Commissioned Officers.

Often a CPO SCPO or MCPO will handle the duies of an officer when an officer is unassigned to a position. FOr example when I served in the Navy, I was a Sonar Tech and we had both a CPO and SCPO in my division. The Officer assigned as ASWO (Anti-SUbmarine Warfare Officer.) transfered out before our new ASWO reported aboard. So STGCS (SW) Don Chapman Served as the ASWO for about a month.

The Rank insignia for a CPO is a Gold Fouled Anchor wih the letters USN in silver. For a SCPO their is a SIlver Star atop the Anchor. For MCPO their is a star on each side of the anchor. For the MCPON (Master Chief Petty Officer of the Navy) gets a third star on top of the anchor. There is only one MCPON at a time and he answers to the CNO (Chief of Naval Operations) who answers to the SecDef.
