A company commander is the commanding officer of a company, a military unit which typically consists of 100 to 250 soldiers, often organized into three or four smaller units called platoons. The exact organization of a company varies by country, service, and unit type. Aviation companies can have as few as 40 personnel, while some specialized companies such as maintenance or training units are considerably larger and may number as many as 500 personnel. In some forces, the second-in-command of a company is called the executive officer (XO). Historically, companies were often formed and financed by individual owners rather than by the state. Sometimes these men were unable to personally exercise leadership and command over the men in their units, and would designate another individual to serve in that capacity.
