Imagine being Austro-Hungarian. You tell your Hungarian captain to order an attack in German, but he's actually Szekely and can't speak standard Hungarian, he orders his Polish troops to attack in Hungarian but half of them speak Kashubian and the other half Silesian, so they can't even understand eachother let alone the f0cking captain. Meanwhile your more complex orders are f0cking unreadable because you're a Tyrolean and you don't bother speaking normal German, no no. Instead you speak a super f0cking obscure Tyrolean dialect no one else speaks and you misinterperet half the f0cking orders you get, tell them to the Hungarian captain even though he can't understand jack sh1t, he proceeds to tell his Polish troops the orders in Hungarian even though they don't understand jack sh1t either. Fed up, you decide to call artillery support instead, but the gunners are all f0cking Romanian and half of them are from Wallachia and the other half speaks the Banat dialect, meaning they understand bumf0ck-nothing. Then you decide to complain to your general but of course, he's Czech but from Moravia, meaning he can't understand Bohemian dialects, of which you speak. So you end up shooting yourself.
