Just a hint: SS was a military group, not the entirety of German population and not even the entire military (Wehrmacht) in that time. The SS certainly didn't have archeologists. It's like saying some Americans of today are "TSA archeologists".
The BBC calls it Nazi archeologists which is still not really correct or fair. The Nazis were a political party, not everyone adhered to it's views. The archeologists might well have been on the other side of the political spectrum but had not much chance to change country. It's like calling all Americans today Trump cashiers, Trump archeologists or Trump teachers. Doesn't make sense.
