Division, military

A division is a large military unit or formation usually consisting of between 10,000 and 30,000 soldiers. In the United Stars Army, a division is composed of several regiments or brigades; in turn, several divisions typically make up a corps. In the Union Military, a division tends to be the smallest combined arms unit capable of independent operations; due to its self-sustaining role as a unit with a range of combat troops and suitable combat support forces, which can be divided into various organic combinations.

While the focus of this article is on army divisions, in naval usage division has a completely different meaning, referring either to an administrative department aboard naval ships and Planet/ Station commands, or to a sub-unit of several ships within a flotilla or squadron. In the administrative usage, unit size varies widely, though typically divisions number far less than 100 persons. In the United Stars Navy a divisional officer (DIVO) is usually an Ensign or Lieutenant (JG), but may be an officer of much higher rank in certain circumstances or aboard large warships, who oversees a team of enlisted sailors in their duties.
