I'd point out that these are armed with Thorpe EM-1 rifles. Which isn't the ideal choice for a British Assault Rifle in this period, but perhaps as erroneous as the AKM the Soviets have. Ideally they'd have Korsac EM-1s, which were developed from 1945 to 47, as in another case of technology somehow developing faster than possible (like the AK) the real Thorpe EM-1 didn't see a change to the configuration it appears in here till 1947; so must have seriously rushed development time to appear in use in 1947.
I can't place the goggles. The British did have Type E "Tabby" Night Vision Goggles in service, however they had longer tubes and a different mounting system. These look much more like the No1 Mk1 Goggles of the 70s-albeit simpler-, but NVGs aren't an area I have knowledge on. If they are fictional they'd look better with the 70s goggle's cloth covering over the wires to make them look a bit cruder.
Oh, and I see a heavy weapon and ammo bearer, but who's the Sergeant supposed to be?
