Editing Corps (section)

====France====
The [[French Army]] under [[Napoleon I]] used corps-sized formations ({{langx|fr|corps d'armée}}) as the first formal combined-arms groupings of [[division (military)|division]]s with reasonably stable manning and equipment establishments. Napoleon I first used the {{lang|fr|corps d'armée}} in 1805. The use of the {{lang|fr|corps d'armée}} was a military innovation that provided Napoleon I with a significant battlefield advantage in the early phases of the [[Napoleonic Wars]]. The corps was designed to be an independent military group containing cavalry, artillery and infantry, and capable of defending against a numerically superior foe. This allowed Napoleon I to mass the bulk of his forces to effect a penetration into a weak section of enemy lines without risking his own communications or flank. This innovation stimulated other European powers to adopt similar military structures. The corps has remained an echelon of French Army organization to the modern day.
