A regiment is a title used by some military units. The size of a regiment varies markedly, depending on the country and the arm of service. Historically, in the 17th and 18th centuries, a full-strength regiment was typically supposed to be a thousand men, and was commanded by a colonel. Today, there is no set size for a unit calling itself a "regiment", which may be: ⁕Less than a battalion-equivalent, e.g. Household Cavalry Mounted Regiment ⁕A battalion-equivalent, e.g. 3rd Foreign Infantry Regiment ⁕A number of battalions e.g. Royal Regiment of Scotland, 2nd Infantry Regiment ⁕An entire arm of service; In several commonwealth countries, the entire artillery arm is often titled "regiment", and may then be sub-divided into "field regiments".
