A private is a soldier, usually with the lowest rank in many armies. Soldiers with the rank of private may be conscripts or they may be professional (career) soldiers.
Warrant officer (WO) is a rank or category of ranks in the armed forces of many countries. Depending on the country, service, or historical context, warrant officers are sometimes classified as the most junior of the commissioned officer ranks, the most senior of the non-commissioned officer (NCO) ranks, or in a separate category of their own. Warrant officer ranks are especially prominent in the militaries of Commonwealth nations and the United States.
Military ranks are a system of hierarchical relationships, within armed forces, police, intelligence agencies or other institutions organized along military lines. The military rank system defines dominance, authority, and responsibility in a military hierarchy. It incorporates the principles of exercising power and authority into the military chain of command—the succession of commanders superior to subordinates through which command is exercised. The military chain of command constructs an important component for organized collective action.
A non-commissioned officer (NCO) is a military officer who does not hold a commission. Non-commissioned officers usually earn their position of authority by promotion through the enlisted ranks. In contrast, commissioned officers usually enter directly from a military academy, officer training corps (OTC) or reserve officer training corps (ROTC), or officer candidate school (OCS) or officer training school (OTS), after receiving a post-secondary degree.
Corporal is a military rank in use by the armed forces of many countries. It is also a police rank in some police services. The rank is usually the lowest ranking non-commissioned officer. In some militaries, the rank of corporal nominally corresponds to commanding a section or squad of soldiers.

A midshipman is an officer of the lowest rank, in the Royal Navy, United States Navy, and many Commonwealth navies. Commonwealth countries which use the rank include Canada, Australia, Bangladesh, Namibia, New Zealand, South Africa, India, Pakistan, Singapore, Sri Lanka, and Kenya.
In a military navy, a rate or rating, and sometimes known as a bluejacket in the United States, is a junior enlisted sailor who is below the military rank of warrant officer. They are not a commissioned officer. Depending on the country and navy that uses it, the exact term and the range of ranks that it refers to may vary.
A petty officer (PO) is a non-commissioned officer in many navies and is given the NATO rank denotation OR-5 or OR-6. In many nations, they are typically equal to a sergeant in comparison to other military branches. Often they may be superior to a seaman, and subordinate to more senior non-commissioned officers, such as a chief petty officers.
Seaman is a military rank used in many navies around the world. It is considered a junior enlisted rank and, depending on the navy, it may be a single rank on its own or a name shared by several similarly junior ranks.
Sub-lieutenant is usually a junior officer rank, used in armies, navies and air forces.
Leading seaman is a junior non-commissioned rank or rate in navies, particularly those of the Commonwealth. When it is used by NATO nations, leading seaman has the rank code of OR-4. It is often equivalent to the army and air force rank of corporal and some navies use corporal rather than leading seaman.
An acting rank is a designation that allows a soldier to assume a military rank—usually higher and usually temporary. They may assume that rank either with or without the pay and allowances appropriate to that grade, depending on the nature of the acting promotion. An acting officer may be ordered back to the previous grade. This situation may arise when a lower-ranking officer is called upon to replace a senior officer, or fill a position higher than the current rank held.
Able seaman is a military rank used in naval forces.
Ordinary seaman is a military rank used in naval forces.
A passed midshipman, sometimes called as "midshipman, passed", is a term used historically in the 19th century to describe a midshipman who had passed the lieutenant's exam and was eligible for promotion to lieutenant as soon as there was a vacancy in that grade.
Royal Navy ranks, rates, and uniforms of the 18th and 19th centuries were the original effort of the Royal Navy to create standardized rank and insignia system for use both at shore and at sea.
