Division

Divisions are rather large units, and are independant field units. They are temporary, and contain brigades. They are the second smallest independant field units, and as such they still use junior staffs (captains and majors) as opposed to senior staffs (lieutenant colonels and colonels).

Structure
A division will consist of two to four brigades, along with a junior command staff. The junior command staff consists of a commander, a second in command, an administrative officer, a medical officer, an intelligence officer, a signals officer and an operations officer.

The command staff consists of the officer commanding (a major general), who is in directly in charge of his division, as well as the second in command (a brigadier general, or sometimes colonel), who is the assist commander of the division.

The administrative staff contains the general administrative officer (a major), who is in charge of administration. The medical officer (also a major), who is in charge of the division's medical elements. The intelligence officer (a captain), who is in charge of intelligence units and the intelligence gathered by them. The signals officer (a captain), who is in charge of the division's communications and will, less commonly than a brigade's singals officer, act as a liason officer for his unit. As well as the operations officer (a lieutenant colonel) who works closely with the officer commanding, second in command and intelligence officer to plan operations and movements of the division.

Role
A division's role is similar to other independant field units, that being they provide military force in a given area. Divisions are in charge of rather large areas, but not an entire front or theatre. In the marine corps, a division is the name given to a unit, led by a major general, which is responsible for the security of a battle fleet. For ground forces of the marine corps, a division will cover an area of landing zones, usually a small division will be the smallest invasion force, as it can provide armour and infantry support; although brigades are technically the smallest landing force.

Integration
A division will contain two to four brigades. Usually, a division will contain at least one infantry brigade and one armour brigade, although it is also possible to have an infantry or armour division. Usually, the smaller the theatre, the more likely a division will be mixed. A division is led by a major general, and there are two or more divisions in a corps. Divisions are numbered within their military and are labelled by their country and type (example: First Canadian Mixed Division). A division may be an infantry division, an armour division, or a mixed division.
