In many European languages, the term Major is a military rank, implying seniority at one of usually various levels of rank. For example:

"General-Major" or "Major-General", denoting a senior ranking general officer.
"Captain-Major", denoting a mid-level command status officer (immediately superior to the rank of a land-forces Captain but immediately subordinate to the ranks of Colonel or Lieutenant Colonel.
"Sergeant-Major" denotes the most senior sergeant of a large military unit.

In the US Army and US Marine Corps, a Major is typically a staff officer, either a battalion Executive Officer (XO) (second in command), or a battalion staff officer such as the Operations Officer (S-3).

Most often, when the term 'major' occurs unhyphenated, in conjunction with no other indicator of rank, the term refers to the rank just senior to that of a land-forces 'captain'. In some countries, notably in France, an unhyphenated "major" derives from "sergeant-major", a senior-level sub-officer rank.
