petty officer

A petty officer is a non-commissioned officer in many navies and is given the NATO rank denotion OR-6. They are equal in rank to sergeant in the British Army and Royal Air Force. A petty officer is superior in rank to leading rate and subordinate to chief petty officer, in the case of the British armed forces

A low-ranking officer

A policeman who is tasked with handling minor offenses like having a "loud" party or swiping a candy bar.

The Navy designation for an enlisted non-commissioned officer of the paygrade E-7 and above. Subsequent ranks of Chief include Senior Chief (E-8) and the Master Chief (E-9). The equivalent in military rank to a Sergeant 1st Class, Air Force Master Sergeant, and Marine Corps Gunnery "Gunny" Sergeant.

Chief Petty Officers (CPO's) wear khaki uniforms and a gold, fouled anchor with silver super-imposed USN across said anchor. Senior Chiefs have one silver star, master chiefs have two silver stars, and the Master Chief Petty Officer of the Navy has 3 stars.

The Chief is often a mid-level to upper-level supervisor of department or workcenter operations aboard US Navy commands. The Chief is theoretically responsible for the safety, conduct and training of sailors under their respective command.

Normally it takes years of training, sea-time, and over-the-top performance for a First Class Petty Officer to qualify for Chief. Chief-selects who pass the Chief's test are considered "board eligible" and their promotion package is reviewed by an eligibilty board. This board is manned by fellow CPO's. Chiefs choose their own members.

The Chief's Mess is often called "the Goat Locker.

Chiefs generally come in one of two varieties, but these are not all-encompassing:

One: The Hard-Charger. This Chief never quits, and expects the best out of everyone, at all times. Usually holding a coffee mug in their hand, heavily stained with the remnants of many cups of coffee. The Hard Charger is usually a chief who will expect the job to get done, done right the first time, or if not, to have any deficiencies rectified, immediately. These chiefs are usually considered by subordinates to be difficult to work for and a "pain in the butt". However difficult they may be to work for, the results of working for a hard charger speak for themselves.

The lazy chief - the lazy chief also holds the sacred coffee mug of Chiefhood. Most of the work done by the lazy chief is actually accomplished by their leading 1st class or subordinate petty officers/seamen. The lazy chief will often take credit for others' hard charging. These chiefs will often, in no particular frequency; come in late without holding ones' self accountable to muster times, take extended lunches, skip out of work due to personal requirements off-site, leave early due to inactivity. These chiefs do not always have the best interest of their sailors in mind. These are the chiefs that will end up taking space from hard working sailors, preventing their subsequent promotion to CPO. Furthermore, like the Hard Charger, the results of working for a lazy chief are usually self-evident, which generally include extra time spent fixing what's gone wrong, cutting into liberty time.

In general, the Chief is a man/woman to respect, admire, and look up to for guidance and advice. Once a Chief, always a Chief.

The Master Chief Petty Officer John-117 is a character of the Halo franchise, his only known name is John. He is known by many as SPARTAN-117, and more as the Master Chief, due to his rank. He is the last remaining SPARTAN-II as of late 2552. He was selected at the age of five to be in the SPARTAN augmentation program, meant to create super-soldiers to quell the Insurrection. The Insurrection was a rebellion from the UNSC. It was mostly destroyed by the end of the Human-Covenant War.

John, along with other SPARTAN-IIs, was augmented with various things. Not all SPARTAN-IIs survived, however. The survivors gained enhanced speed, strength, stamina, and agility. They were excellent tacticians and leaders due to their teaching of nearly every historically significant battle, and then some. In the end, though, John was lost after the destruction of UNSC Forward Unto Dawn. He was a hero, and died saving humanity.

Meanwhile, he has been mocked across the internet for the Halo story being poor and him being a 'fail'. While the story is not the greatest, surely it is not the worst, or it would be so bad it's good. Of course, your mileage may vary...

Please do not confuse with Mister Chief.
