Captain

Captain is the name most often given in English-speaking navies to the rank corresponding to command of the largest ships. The equivalent rank in many navies is Ship-of-the-Line Captain. The command of a ship is most often given to the naval rank equivalent to a commissioned officer between commander and commodore or rear admiral. In military armies, a Captain is an officer rank historically corresponding to command of a company of soldiers. The rank is also used by some air forces and marine forces.
