Hello Historians,
i was wondering if you can help me identify the title of a book by its cover. The book title on the image is actually photoshopped on, and the original image overlaid with this one of a soldier in uniform, aiming a rifle. The name of the original book is known, the photoshopped one if fake - what i am interested in is if the soldier image can be found anywhere and what it depicts. Therefore i would like help with characterizing the image - what army is the soldier from, which time/war (ww1 or ww2) etc deduced from rifle, uniform, helmet, backback etc.

The helmet and rifle seem especially reconizable, maybe a dishpan/brodie helmet which would signify US or UK army? The rifle's magazine, trigger guard and lenght look very discernible, though i have no experience in identifying those. Any help would be appreciated. A reverse image look up did not yield anything, and i am working through the milrecords aides from the ressources right now. Thank you in advance.
