Military organization of the Germanic peoples
By military organization of the Germanic peoples is meant the set of forces that made up the armies of the Germanic peoples, including the organization of their units, their internal hierarchy of command, tactics, armament and strategy, from the Cimbrian Wars (late 2nd century B.C.) to the Marcomannic Wars (mid-3rd century A.D.). After this period a whole series of confederations of peoples (from the Alemanni to the Franks, Goths, and Saxons) were generated, each with its own internal military organization, which will be analyzed individually and separately.
