[5] The historian Christoph Rass called Yerger's book Riding East about the SS cavalry brigade a "whitewashing and in its interpretation more than concerning presentation" of the unit's operations.
Yerger's book, according to Rass, is "an example of a downplaying and uncritical history of a Waffen-SS unit, whose participation in numerous war crimes is well documented".
A telling example of Yerger's treatment of the sources, Rass writes, is that "he cites the thanks of General Schellert to the SS cavalry brigade of 6 November 1941, but only mentions its 'action on the flank' and not also 'in the back' of the division".
[7] In The Myth of the Eastern Front: The Nazi–Soviet War in American Popular Culture, Ronald Smelser and Edward J. Davies describe Yerger as a "guru" in the scene of those who romanticize the Waffen-SS.
With publications that contain more photographs than text, and a generally hagiographical treatment of their subjects, they write, Yerger's works do not provide a frame for historical interpretation, but create a romanticized world of their own, characterized by bravery and sacrifice.
