Funny thing about Boney's Imperial guard. The titles of old, middle, and young guard are based on timing. That is how long the persons in said unit served Napoleon. Old guard only applied to whole units in the 1st Grenadiers and Chassuers. After that the old, middle, young guards are mixed up. All officers in guard units were titled old guard (IF I'm reading my souce right). The 2nd Grenadiers, Chassuers, and Fusiliers sergents were old guard. The corporals and ranks were middle guard. The 3rd Grenadiers was all middle guard. The young guard were Voltigeurs, Tirailleurs, Flanquers and National Guards. And the National guards (Marie-Louise infantry) were militia units of old men and young boys. And they won't exist until the end of the tech tree/campagin (however CA does the French revolution) anyway. Before the French revolution the household units of the French king are Garde du Corps (who are the decendants of the Scots guard and mounted archer units from Medieval 2), Gardes Françaises, Gardes Suisses, and the royal Musketeers.
But really you can divide infantry into 5 types. Militia (national guards, Yoemanry, landwehr, etc), line infantry, grenadiers, light infantry (although you might be able to split them into formed and irregular types like Cossacks 2 does), household (or guards) units.
A personal hope of mine is that CA includes Russian Streltsy infantry. Imagine Cossack musketeers armed with Bardiche's for musket props. A 16-17th century unit yes, but still around in 1700.![]()
