Instructions Chapter 1 Military Districts and Motorized Infantry Divisions Military districts and maneuver divisions are the highest-level tactical organizations in the Ground Forces.
Military districts are geographical entities, but are also a level of command.
For more information on infantry and mechanized infantry divisions, see Chapter 2 . For more information on separate and divisional brigades, see Chapters 3 and 4 . Divisions can be either standing or mobilized from the reserves. Standing divisions may exist in districts along an international border, in districts that contain historically threatened avenues of approach, or around critical cities or facilities. Divisions mobilized from the reserves may draw combat support and combat service support from reserves or receive them from the national asset pool.
