Prussia was not a country with an army, but an army with a country.

The Prussian Army has no ideals, no true spiritual strength; neither has the whole nation. All they have is gross materialism. ... The German soul has a place for the glorification of brute force, for the notion of war as a colossal looting campaign. That is all it holds. It is not much.

[I]t was the inner elite (the general staff) of one of the most caste-bound and privileged officer corps in Europe—the Prussian—that was the first to succumb to the new world of industrial change, and transform itself into a group of "industrial" managers and technicians... Railway transport, swift mobilization, and new equipment called for a high degree of technical skill and competence. Education and intelligence in conscripts required the same attributes in officers. Above all, the Prussian army, in the era of Moltke, Roon, and Bismarck, was the key to Prussian unification of Germany; neither the officer corps nor the nation could afford it to be less than efficient and modern. By 1870 the revolution was almost complete; the first European army of the modern era had been seen in action in three swift wars.

The German army is a machine, and machines can be broken!

If you are good soldiers, you must also be good Christians and religious at heart. He who is no good Christian is no good man and also no Prussian soldier, and can under no circumstances perform what is required of a soldier in the Prussian Army.

A few days ago in a Berlin theatre the audience burst into spontaneous applause merely because the orchestra began to play an old military march—not a German march, either, but an Austrian one, the Radetzky march. Do not think that this meant a demonstration in favour of a war of revenge—not a bit of it. But the army and all that goes with it has been in the tradition of the German people for a hundred years and it would betray a very poor knowledge of men to believe that such a tradition could be uprooted when people is bidden by the terms of a treaty to give up compulsory military service.

The soldier and the army, not Parliamentary majorities and decisions, have welded the German Empire together. I put my trust in the army.

War is the life-element of an army.

A standing army is like a standing member. It's an excellent assurance of domestic tranquility, but a dangerous temptation to foreign adventure.

In 1933, before the Waffen-SS, there was a portion of the Nazi Party’s Schutzstaffel (SS), armed and trained along military lines and served as an armed force. These troops were originally known as the SS-Verfügungstruppen, the name indicating that they served at the Führer’s pleasure. By 1939, four regiments (Standarten) had been organized.
The Verfügungstruppen took part in the occupation of Austria and Czechoslovakia side by side with the Army (Heer). During the months preceding the outbreak of the war, they were given intensive military training and were formed into units that took part in the Polish campaign. In addition, elements of Death’s Head formations (Totenkopfverbände), which served as concentration camp guards, also took to the field as combat units.
During the following winter and spring, regiments that had fought in Poland were expanded into brigades and later divisions. This purely military branch of the SS was known at first as the Bewaffnete SS (Armed SS) and later as the Waffen-SS. The regiment Leibstandarte SS Adolf Hitler eventually became a division of the same name; the Standarte Deutschland together with the Austrian Standarte Der Führer formed the Verfügungs Division, to which a third regiment, Langemarck, was later added, creating the division Das Reich; and the Totenkopf units were formed into the Totenkopf Division. These three divisions were to be the nucleus of the Waffen-SS in its subsequent rapid expansion.

Quoted by Friedrich Engels in Waldersee über die französische Armee, 1861

Let us pass on to Prussia. Formerly a vassal of Poland, it grew to be a first-rate power only under the auspices of Russia and through the partition of Poland. If Prussia should lose its Polish prey tomorrow, it would sink back into Germany instead of absorbing it. In order to maintain itself as a power distinct from Germany it must lean for support on the Muscovite. Its recent increase of power, far from relaxing the bonds, has made them indissoluble. Besides this increase of power has increased Prussia’s antagonism with France and Austria. At the same time Russia is the pillar on which the arbitrary rule of the Hohenzollern dynasty and its feudal tenants rests. It is its safeguard against popular disaffection. Consequently Prussia is not a bulwark against Russia, but its predestined instrument for the invasion of France and the digestion of Germany.

I have left the obvious, essential fact till this point, namely, that it is the Russian Armies who have done the main work in tearing the guts out of the German army. In the air and on the oceans we could maintain our place, but there was no force in the world which could have been called into being, except after several more years, that would have been able to maul and break the German army unless it had been subjected to the terrible slaughter and manhandling that has fallen to it through the strength of the Russian Soviet Armies.

Michael: "March here, march there, present arms, where's your cap?" — you've no idea, the whole Army's obsessed with playing at soldiers.
