Dunnigan 

I assume the cryptic reference "p.171, Dunnigan" refers to something by wargames designer(!) Jim Dunnigan, most likely the edited collection The Russian Front: Germany's War in the East, 1941-45 (first ed., as War in the East, New York: Simulations Publications, 1977; new UK ed. London: Arms and Armour Press, 1978). However, it is not possible to determine which edition (UK or US, etc.) of the book is being cited. As requested above by Pēters on 16 April, please provide a proper citation, ideally also giving the article from the collection being quoted. An incomplete reference is almost more useless than no reference at all. There seems to be a lot of scrutiny of so-called "Latvian" or "German" sources, but what is the quality of the scholarship being quoted elsewhere in the article? No-one will ever be able to judge, if the bibliographic details remain hidden from us. —
