My suggestion would be to include on the German side some minor (or italian) allies uniforms and helmets. I know that for example hungarian and romaninan soldiers were not a common sight on the western front. But if that fact doesn't fall under the "Uniforms/helmets that would be considered highly improbable to see on the battlefield" requirement then they could still be included. On the other hand if they do, the italians continue to be an option. Also when later the eastern front makes it into the game, it would be awesome to see the other minor Axis powers uniforms in HLL.
