The SS and wehrmacht are two different organizational structures. The Wehrmacht is the national army of Germany, a legitimate soldier. The Waffen-SS was a military organization formed by the Nazi Party, which was above the regular forces of the state and was the private army of the Nazi Party, and they were called SS.
There are many sources that like to define the Waffen-SS as Hitler's personal army, which is actually true. As the leader and dictator of the Nazi Party, the SS, which swore allegiance to Hitler, did bear this nature.
Strictly speaking, the SS needed to be slightly distinguished from the Waffen-SS, which was a defensive organization set up by the Nazi Party, especially after the Bloodbath storm troops on the Night of the Long Knife, which developed rapidly and then usurped Germany's secret state security posts and took control of police facilities. When it grew with the Nazi Party, it developed its own militarized armed group, the Waffen-SS.
According to the initial practice at that time, the Waffen-SS was initially the "Waffen-SS Special Mobile Unit", which belonged to the "paramilitary organization licensed and trained by the Wehrmacht", but after that the Wehrmacht could not control this stubble, everything was "nominal".
Politically, the Wehrmacht was nominally loyal to the state, the nation and the people, and the leaders were merely their service recipients. The Waffen-SS, on the other hand, made it clear that the object of their allegiance was to the Fuehrer, the "Party", and that their aim was to defend the Führer and the Party organization and to realize the great line of the Socialist-Workers' Party.
Well, this great line is actually quite dirty, full of extreme racism, social Darwinism, imperialism and fascist culture, but many Young Germans at that time ate this set, and they fanatically regarded Hitler's speech as the dawn of the rise of the nation, looking forward to the supreme future forged by the Germanic nation with iron and blood.
The Waffen-SS was not limited to the German youth, they were armed institutions that served the Nazi Party, so in their development they continued to include personnel from many other countries. For example, the "Charlemagne Division" composed of The French, the "Machete Mountain Division" composed of Bosnian Muslims, the "Nordic Division" composed of Norwegians, the "Galician Division" composed of Ukrainians, the "Russian Liberation Army" composed of Russians, the "Redland First and Second" composed of Latvians and Lithuanians, the "Dutch Division" of the Netherlands, the "Italian Division" composed of Italians, etc. In fact, most of the Waffen-SS were foreigners, and they served the Nazi Party, not Germany.
In addition, they also have the "People's Commando" composed of the elderly, and the "Hitler Youth Regiment" composed of young people, and the old and the young do not let go, as long as they can flicker, they will be fooled on the battlefield.
Sometimes the SS is also the worst in military discipline, so why didn't the Allies catch the SS and like to shoot them? After all, the military camp culture is small, the sense of professionalism of the military is lower than the fanaticism of the Nazi Party, and most of the SS are young and too fierce. Especially in the early battles, the SS was generally effective, but many violations of military discipline were done.
Many SS units received great support from Hitler's policies, so they received better equipment, higher supplies, and the highest quality officers. Hitler even exchanged the cigarette supply in the army food of the Youth League with milk candy in order to prevent his precious youth from being contaminated with cigarettes, while the Muslims of the "Machete" division each received a Qur'an hanging ornament given by Hitler on new year's day.
Hitler regarded the SS as his confidant, "the only army that could be trusted", and he wanted them to be successful, so he did not hesitate to pay attention to all kinds of material contributions. And the several ace units of the Waffen-SS have indeed lived up to the cultivation of the Fuehrer and grown into quite strong combat units, such as the "Empire", "Skeleton", and "Führer Guard Flag Corps", which are simply the aces of the aces, they are fanatical, resolute in battle, cruel in style, and can fight with the enemy with their teeth.
Classmates who like to fight tanks know "Wittmann", he led the crew to kill 138 tanks. In fact, Weitmann was originally a member of the Wehrmacht 19th Infantry Regiment, and in 1936 he was "discharged", and in October of the same year he transferred to the SS sequence and became a member of the "Hitler's Flag Guard" division.
In terms of funding sources, the Wehrmacht is a legitimate army, and the source of military expenditure is of course the defense budget allocation, which is no different from the ordinary regular army. The Waffen-SS, however, was a strange thing, because they were part of the Nazi Party, so of course military expenses were disbursed from party property.
But after the Nazi Party took control of Germany, under the construction of the "party-state integration", how could Hitler turn his troops into a daughter-in-law? So the Wilaffen SS soon became attached to the government and lived on special SS financial appropriations. This practice was tantamount to letting the German state raise a gang of private soldiers for the fascist party, but in Germany at that time, who dared to say anything?
