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.
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.
Lieutenant Commander is a commissioned officer rank in many navies. The rank is superior to a lieutenant and subordinate to a commander. The corresponding rank in most armies and air forces is major, and in the Royal Air Force and other Commonwealth air forces is squadron leader. It is roughly equivalent to the Corvette Captain rank in central European countries and the Captain 3rd rank rank in eastern European/CIS countries.
Brigadier general or brigade general is a military rank used in many countries. The rank is usually above a colonel, and below a major general or divisional general. When appointed to a field command, a brigadier general is typically in command of a brigade consisting of around 4,000 troops.
Commander is a common naval officer rank as well as a job title in many armies. Commander is also used as a rank or title in other formal organizations, including several police forces. In several countries, this naval rank is termed as a frigate captain.
Staff sergeant is a rank of non-commissioned officer used in the armed forces of many countries. It is also a police rank in some police services.
Sergeant major is a senior non-commissioned rank or appointment in many militaries around the world. Sergeants Major serve as the senior enlisted advisor to the commander.
Lance corporal is a military rank, used by many English-speaking armed forces worldwide, and also by some police forces and other uniformed organisations. It is below the rank of corporal.

Chief Warrant officer is a senior warrant officer rank, used in many countries.
In the United States military, a general is the most senior general-grade officer; it is the highest achievable commissioned officer rank that may be attained in the United States Armed Forces, with exception of the Navy and Coast Guard, which have the equivalent rank of admiral instead. The official and formal insignia of "general" is defined by its four stars.
Before Unification as the Canadian Armed Forces in 1968, the Canadian military had three distinct services: the Royal Canadian Navy, the Royal Canadian Air Force, and the Canadian Army. All three services had a Regular (full-time) component and a reserve (part-time) component. The rank structure for these services were based on the services of the British military, the Royal Navy, the Royal Air Force, and the British Army. The change to a "Canadian" rank structure meant that many of the traditional (British) rank titles and insignia were removed or changed.
The ranks in the Israel Defense Forces (IDF) reflect an individual's level in the military.
Specialist is a military rank in some countries' armed forces. Two branches of the United States Armed Forces use the rank. It is one of the four junior enlisted ranks in the United States Army, above private (PVT), private (PV2), and private first class and is equivalent in pay grade to corporal; in the United States Space Force, four grades of specialist comprise the four junior enlisted ranks below the rank of sergeant.
The Indonesian National Armed Forces (TNI) uses a simplified ranking system for the three branches of Indonesian Army, Indonesian Navy and Indonesian Air Force. Most of the ranks are similar with differences for the rank titles of the high-ranking officers. Exception exists, however, in the ranks of the service members of the Indonesian Marine Corps. While Indonesian Marine Corps is a branch of the Navy, the rank titles of the Marine Corps are the same as those of the Army, but it still uses the Navy's style insignia.
The Special Task and Rescue Team, abbreviated as STAR, serves as the command for elite maritime special operations and underwater divers within the Malaysia Coast Guard. It was established as a rapid reaction force for emergencies within the maritime zone of Malaysia.
The rank insignia of the Federal Defence Forces indicate rank and branch of service in the German Army, German Air Force, or the German Navy.
Lieutenant (abbreviated Lt, LT (U.S.), LT(USN), Lieut and LEUT, depending on nation) is a commissioned officer rank in many English-speaking nations' navies and coast guards. It is typically the most senior of junior officer ranks. In most navies, the rank's insignia may consist of two medium gold braid stripes, the uppermost stripe featuring an executive curl in many Commonwealth of Nations; or three stripes of equal or unequal width.
