With the passage of the National Defense Authorization for 643, the push for modernization and expansion of the military is at an all time high.  To facilitate the growth needed to create new combat divisions for the army, a force redesign will help achieve this through a cadre of established soldiers from existing units forming the core of new units. The Army will shift to a TriganleTriangle concept of organization with three maneuver brigades instead of the previous four. The Division Tactical Group will become the unit of action, coordinating combat support and other enabling elements to its brigades.

Because of the transformation of from Square Division to a Triangle Division, the roles and responsibilities for division types will be redesigned.  A break down of the Division Types follows.
