In this list you can field an "infantry brigade" containing no infantry at all. Indeed, there are no minimums required of any kind.
Don't get me wrong, as a wielder of these very Prussians myself, this complete flexibility suits me just fine

However, I can't help but feel that the infantry brigade in this list really does need either a minimum inserting into it OR an army list condition that says that an infantry brigade must contain at least as many infantry units as cavalry units. After all, the immediately preceding and following Prussian lists (Spring 1813 and 1814) do both have minimums included for infantry brigades; what was it that happened in the Summer of 1813 that meant Prussian infantry brigades could suddenly field no actual infantry ?
