1) Marines wore those exact Marine Unfiorms with Campaign Covers and leggings early on in France. Marines also lived in those exact tents early on in France. And I can document those rifles in France. So there is nothing in that photo that says that it couldn't have been taken in France.
2) Literally EVERY document says it was taken in France.
You keep on saying it's not taken in France, but I can't follow any of your explanations on why you think that.
