Since 618, the Kodiaker Army relied on the Brigade Tactical Group (BTG) organized within the construct of the Square Division concept as a 3+1 design.  This consisted of three mechanized brigades (subdivided into three mechanized battalions with one tank battalion) and one tank brigade (subdivided into fourthree tank battalions and one mechanized battalion).   These brigades were then augmented with Division level support elements to form the BTG with additional artillery, engineers, and logistic enablers.  This was seen as a way to augment the shortfalls of the army during years of downsizing amid lowered budgets and a border crisis that resulted in an active army presence to maintain forward units capable of independent actions at the tactical level.

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.
