In 2301, IMS announced a major revision in the Table of Organization and Equipment (TO&E) for all of its ground military forces. This change was necessary due to changes in military doctrine and the renewed Kafer war offensive up the French Arm.
Under the new TO&E, the armor units formerly inherent to HCRs and HSRs were formed into Armor Battalions.
Battalions are classified by the standard two digit numerical designation with a T suffix.
xxxT Armor Bn (system)
Where xxx is a numerical designation for the regiment, and indicates the chronological order of formation of the battalions,commencing from 10 and system indicates the star system in which the battalion was mustered.
For example, the 11T Armor Bn (Sol) was the first armor battalion to enter service with IMS, and was formed in the Sol system.
 
Each armor battalion contains forty main battle tanks (MBT) in total. It is controlled by a battalion commander in one tank, and consists of three tank companies of thirteen tanks each. Each tank company contains three tank platoons of four tanks each and a company commander in one tank.
All armor battalions consist entirely of one type of tank, either LkPz-VIIIs or M9s. Other types of tanks may be found in IMS service, but are generally in independent units, not attached to the standard armor battalions.Effective tank strength is based on the number of tanks in the platoons, and as such is usually given as being thirty-six tanks; which does not include the command tanks. This results in an HCR having one armor battalion, and a HSR having a single company.
As of 2301, IMS has nine armor battalions at full operational strength.
