I think that was deliberate. Nolan's showing how dehumanizing war is. Same reason it's hard to distinguish the ground soldiers. My father served in Vietnam, and I brow beat him into seeing Saving Private Ryan with me (he's since passed away). His comments to me after seeing that film is that 1) it "got" how disorienting the fog of war is 2) how LOUD war is. Dunkirk achieves the same.
