Quartermaster is a military term, the meaning of which depends on the country and service. In land armies, a quartermaster is generally a relatively senior soldier who supervises stores or barracks and distributes supplies and provisions. In many navies, a quartermaster is an officer with particular responsibility for steering and signals. The seaman is a non-commissioned officer rank; in some others, it is not a rank but a role related to navigation.

A battalion is a military unit, typically consisting of up to one thousand soldiers commanded by a lieutenant colonel and subdivided into a number of companies, each typically commanded by a major or a captain. The typical battalion is built from three operational companies, one weapons company and one headquarters company. In some countries, battalions are exclusively infantry, while in others battalions are unit-level organisations.
