[edit] History

Prior to the professionalization of the armed services of European nations subsequent to the French revolution, a captain was a nobleman who purchased the right to head a company from the previous holder of that right. He would in turn receive money from another nobleman to serve as his lieutenant. The funding to provide for the troops came from the monarch or his government; the captain had to be responsible for it. If he was not, or was otherwise court-martialed, he would be dismissed ("cashiered"), and the monarch would receive money from another nobleman to command the company. Otherwise, the only pension for the captain was selling the right to another nobleman when he was ready to retire.

[edit] Air forces

Due to most air forces being the junior service in most countries, it has adopted ranks from one of the other services. Many, such as the United States Air Force, use a rank structure and insignia similar to those of the army.

However, the United Kingdom's Royal Air Force and the air forces of many Commonwealth countries use a rank structure in which Flight Lieutenant is OF-2. A Group Captain is OF-5 and was derived from the naval rank of captain.

In the unified system of the Canadian Forces, however, the air force rank titles are identical to that of the Army, while the rank insignia is common to Army, Navy, and Air Force; thus, an air force or army captain wears two gold stripes on sleeve or epaulet (the same as a naval lieutenant), while the modern equivalent of the British group captain bears the rank and insignia of colonel, i.e. four gold stripes on sleeve or epaulet (same as a naval captain).
