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 lieutenant is a junior commissioned officer rank in the armed forces of many nations, as well as fire services, emergency medical services, security services and police forces.
Brigadier is a military rank, the seniority of which depends on the country. In some countries, it is a senior rank above colonel, equivalent to a brigadier general or commodore, typically commanding a brigade of several thousand soldiers. In other countries, it is a non-commissioned rank.
Major is a senior military officer rank used in many countries. When used unhyphenated and in conjunction with no other indicators, major is one rank above captain in armies and air forces, and one rank below lieutenant colonel. It is considered the most junior of the senior officer ranks.
