Based on the reforms of Archduke Charles for the 1809 campaign and functioning as a sort of counter to PDguru's own Colonne d'Attaque, I present two new units. German & Hungarian Infantry battalion mass. 
Austrian battalions were quite a bit bigger than the French's so these units are huge if you're playing with vanilla mod's unit size. That being said, their accuracy is pretty terrible; their reloading skill, ammo count and melee effectiveness however is increased by a large amount.
So feel free to edit the unit stats to change those to your liking. 
The Germans have the old casques while the Hungarians have the new shakos. The reasoning being that according to some sources I've been going through while making this, while all the Infantry was supposed to have shakos, logistics being what they are, only the Hungarian units had received them in time for the 1809 campaign.
They can form pike square that kinda works as square formation, same way the closed column formation worked in real life. They hold it for a bit when they make contact with cavalry but eventually break formation and get massacred lol. Don't know if it's just my game so I'd love to know others people's experiences.
Credits to PDguru and his modding genius for the idea, the battle_entities_table, & the cdir_unit_qualities_tables.
Credit to the LME team for pretty much everything else lol.
In unit_tables you'll see the translated names for the units to put into whatever localisation file you're using.
Intended to be used with LME4 but should be able to be used as a standalone file with other mods.
File is in movie format so just plop this bad boy straight into the data folder and you should be good to go.
