This list of formation types is designed to help beginning Republique players to relate real life Napoleonic formations with those used for game play. The list indicates only very basic averages, and players should remember that real life units varied enormously in both quality and size. In some armies, "green" troops were fully trained and could perform very impressively. In other cases, regular troops who had been allowed to become demoralized put in very poor performances. Unit descriptions include type, average size (number of bases) and average troop grade. The infantry lists also include skirmisher availability and quality. The cavalry lists include a classification of cavalry types. At the beginning of each section is a short description of each army, along with an average ratio of artillery batteries to infantry/cavalry bases. These recommended artillery ratios are purely for reference to help players develop a fair sense of usage.

The Skirmish column describes the number and type of skirmish markers which a unit type is allowed to deploy. A "One" indicates that the entire unit may deploy only one skirmish marker at any one time. "All" indicates that unit type may deploy one skirmish marker per active combat base present.

Prussia (1806)

In 1806, the Prussian Army was one of the more intensely drilled and enthusiastic forces in the world, but it had not seen serious (or prolonged) combat in decades and its troops were heavily dependent on their supply train. The army was also hampered by its antiquated system of grand-tactical maneuver which restricted battlefield deployment and mobility. The senior officer corps was also fraught with divisions which could interfere with timely reaction to enemy movements.

The 1806 Prussian Army used the Divisional Column system. German Duchies through 1807 will tend to use Prussian organization. Recommended artillery ratios: 1 battery per 7 bases (varied greatly). Command category is Cumbersome. The 1806-1807 army never used the French maneuver system.

Prussia (1813)

The Prussian Army of this period was recovering from its annihilating defeats at the hands of the French in 1806. They had brilliantly maintained a rotating system of reserve training, but this could not replace a fully trained standing army, nor could it help the terrible supply situation. As a result, the 1813-1815 Prussian Armies were plentiful and enthusiastic, but poorly trained and equipped. The Prussian Army of 1812-1814 used the Corps system. Each corps used "brigades" which were the equivalent of divisions used by other nations. They are shown as Divisions in the game in order to keep the order system clear. Prussian artillery should be considered green. The Prussian Army began using French formation change system in 1810.
