The German approach to the subject of military organization is one of extreme flexibility. The underlying thought is that in view of the rapid progress of science as applied to war, organizational practice must remain flexible if it is to take advantage promptly of new scientific development, to exploit various kinds of situations, and to cope with all types of enemies. Efficient combat effectiveness of an organization is always considered a primary requisite. It should therefore be remembered that although the organization of German antiaircraft units is founded on certain basic principles, experimentation with new tactical doctrines, economy of military manpower and equipment, or the considered needs of a task force situation may cause the organization of certain AA units to vary from normal.
