There are many photos, videos even books about nazi muslim bosnians(bosniaks). There were tens of thousands of them that fought side by side with the nazis (Für Prophet und Führer by David Motadel is a book where you can check some of their atrocities. This book is also interesting because it shows how Albanians, Crimea Tatars and Caucasus Muslims also joined the nazis. The think about muslims bosnians is that under the Turks they, as converts, were treated better than christians for 2/3 centuries and also committed atrocities against christians that many times were also enslaved to converts. When the turks were fought back and got to go back to Turkey all the converts lost their privileges and this is why in the wars, many time they will side anybody against their christians ex brothers.
