Prussian ArmyThe Royal Prussian Army (1701–1919, Königlich Preußische Armee) served as the army of the Kingdom of Prussia. It became vital to the development of Prussia as a European power. The Prussian Army had its roots in the core mercenary forces of Brandenburg-Prussia during the Thirty Years' War of 1618–1648. Elector Frederick William developed it into a viable standing army, while King Frederick William I of Prussia dramatically increased its size and improved its doctrines.
WehrmachtThe Wehrmacht (ˈveːɐ̯maxt, defence force) were the unified armed forces of Nazi Germany from 1935 to 1945. It consisted of the Heer (army), the Kriegsmarine (navy) and the Luftwaffe (air force). The designation "Wehrmacht" replaced the previously used term Reichswehr and was the manifestation of the Nazi regime's efforts to rearm Germany to a greater extent than the Treaty of Versailles permitted.
German Army (1935–1945)The German Army (Heer, heːɐ̯; army) was the land forces component of the Wehrmacht, the regular Armed Forces of Nazi Germany, from 1935 until it effectively ceased to exist in 1945 and then was formally dissolved in August 1946. During World War II, a total of about 13.6 million soldiers served in the German Army. Army personnel were made up of volunteers and conscripts. Only 17 months after Adolf Hitler announced the German rearmament program in 1935, the army reached its projected goal of 36 divisions.
Infiltration tacticsIn warfare, infiltration tactics involve small independent light infantry forces advancing into enemy rear areas, bypassing enemy frontline strongpoints, possibly isolating them for attack by follow-up troops with heavier weapons. Soldiers take the initiative to identify enemy weak points and choose their own routes, targets, moments and methods of attack; this requires a high degree of skill and training, and can be supplemented by special equipment and weaponry to give them more local combat options.
