Eventually yeah, he is looking into replacing the Grenzers with the sharp shooter Landwehr and bringing back a slightly different looking Austrian with that helmet when he has time.
Also, the latest update I quite like the new minor features like the tweaked UI (and happy to hear you are considering flavour layouts for other factions when you are done with the final replacements) the new animations are much more solid (sword melee efficiency with my guys has increased!) and the new replacement sounds are well picked.
