For the most part it is, in the first two pics it looks like this a ww1 british helm but, some of the british wore them still in ww2 but in the snow one it looks like this its the swedish helmet and the clothes in the first look like this a standard american paratrooper uniform with ww1 british helm while the second is american medic with british ww1 helm and the third is an american (or german i get this from the coat) medic with swedish helm, so by all standards yes acurate with very slight descrepences
sorry for it being long, I just love history
