Archive.org contains a scan of an 84-page pamphlet, called "Our Red Army Ally" that purports to be a document published by the United States War Department in 1945, for the purposes of training American Soldiers how to deal with their USSR counterparts.
DA PAM 21-30 Our Red Army Ally 1945-04-23.
The descriptions are so against stuff prevalent in mainstream Western press, movies and games today, that reading all this in English was quite a surreal experience for me.
Is the description of this document accurate? Is it an authentic pamphlet issued to US soldiers?
