well, they need prussians so everybody counts They even allow 1813 styled line infantry if they wear bicorns
which is a bit .... Nah, I don't say anything.
I won't be at Jena, cause I am 1813 and the week after is Leipzig, which will be much smaller caused by Jena....
Also my unit had some problems back in 2006, where even Landwehr took part in the battle. Probably, because the Landwehr were in a big prussian line, where the rest have worn shako withouth Cover.
(beside, there was only one proper 1806 line back there, the other 2 where the Landwehr-Line-Infantry and a mixed line containing 1813 Prussian guard, 1806/1813 Saxon Guard and a 7-year-wars-line)
