First of all, the German SS had no air combat units, and German pilots were not responsible for fighting on land. The Luftwaffe had formed 2 batches*** of more than 20 air force field divisions, but these air force field divisions were staffed by "wealthy" ground crews from the air force, and it was not possible for trained, valuable pilots to take on ground combat missions. The Air Force field divisions were staffed by the Air Force's "rich" ground crews, and it was impossible to put trained, valuable pilots on ground combat duty.
At this point, the relationship between the SS and the pilots is basically clear - the SS fights on the ground, the pilots fight in the air. The issue may well be the difference between Germany's Air Force field divisions and the SS.
The SS in Germany was a broader concept, in which those responsible for combat were the Waffen SS, which were, with the exception of a small number of elite Panzer and Panzer Grenadier divisions (mechanized infantry divisions), the vast majority of which were armed divisions forcibly recruited from the occupied territories. Since they were not part of the same system as the Wehrmacht, they had their own logistical and command characteristics; the elite units tended to fight more bravely, but they also treated prisoners of war and enemy civilians more viciously. The armed divisions, on the other hand, have a knack for bullying civilians and basically collapse at the touch of a button once they hit the battlefield.
The Air Force field divisions were formed by G?ring in response to pressure from Hitler and the Army, who were unhappy with the large number of "surplus" personnel in the Air Force, and to supplement the Army's severe shortage of human resources by taking personnel from the Air Force to form units that were theoretically under G?ring's command. These units, with very few exceptions, were admittedly less effective due to poorly trained personnel and inexperienced commanders, insufficient heavy weapons, and severe shortages of personnel (often less than 8,000, as opposed to the German divisions of at least 12,000).
The main difference between the Waffen-SS and the Air Force Field Division is: the Waffen-SS at least part of the army combat effectiveness is reliable, there is a large war effort, while the Air Force Field Division basically did not have to take the record; the Waffen-SS is completely outside the system of the Wehrmacht, the Air Force Field Division belongs to the system of the Wehrmacht, but does not belong to the army; the Waffen-SS commander-in-chief is Himmler, the Air Force Field Division command theoretical Commander-in-Chief is G?ring.
