The reason Arstal I thought the bombard/cannon/field artillery progression was a good idea is the artillery never seems to quite match the infantry in the gunpowder age. You often have musketmen (which I think of as 16th-17th century infantry with arquebus and/or matchlock muskets) fighting with trebuchets

then you get chemistry and all of a sudden the cannon wipes the floor with the musket man

12 vs 9 if this represents the 18th century I don't think its accurate artillery did not dominate musket armed infantry that much. A bombard would represent well early artillery in the 16th to 17th century which was great against fortifications but not so good in the field. Artillery didn't start catching up to infantry and cavalry until about the 18th century, hence the str 10 cannon with the str 10 fusilier (and str 10 knight). I thought the str 12 field artillery was necessary to represent the muzzle loading rifled guns used in the American Civil War and wars in Europe like German wars of unification and Italian wars of unification etc. The rifled guns had a substantial increase in range over smoothbores.
so I would imagine these groupings
16th-17th century tech (w/gunpowder) musket str 9/bombard str 5 (x2 vs city)/ knights str 10
18th century (w/chemistry) fusilier str 10/cannon str 10/ knights str 10 (unless we make a str 10 hussar unit with 25% vs cannon

)
late 18th century-mid 19th century (with military science) grenadier str 12/field artillery str 12 / cuirassier str 12
mid 19th to late 19th century (w rifles/miltary tradition) riflemen str 14/ field artillery str 12/ cavalry str 15
I know field artillery is a bit odd because Napoleon only had smoothbore cannons but I think artillery tactics became so devastating during the napoleonic wars that it justifies giving them a str 12. While during the Civil War artillery actually did suffer in relation to infantry because rifles could hit the artillery crews easily so they had to keep their distance unlike napoleonic artillery which could get relatively close.
Oh and the reason I would have the grenadiers come after the fusilier is I thought it would represent the advancement of infantry tactics from the fairly rigid tactics of the 18th century in which everyone fought in lines to the Napoloeonic tactics which were a more exotic tactics of column attacks, skirmishers, squares etc. Of course this is all simplification, grenadiers certainly served with fusiliers but it isn't very romantic to call the unit "Napoleonic Infantry" Grenadier has a nicer ring
Anyway thats my two bits, hopefully you would implement some types of changes Wolf. But I think its a great idea to move castles back to feudalism.
