France

Imperial Guard Infantry:

• Chasseurs: NCF 3.
• Zouaves: NCF 10.
• Grenadiers. Nothing perfect here. However, you can use MFN 5*, MFN 20* grenadiers and chasseurs (Napoleonic), the new pack of Napoleonic grenadiers MFN43* Old Guard grenadiers attacking may also be used, but needs some additional work (not a great pack, IMO). Also, Austrian Grenadiers attacking, MAN 15* may be used with some work on bearskins.
• Voltigeurs : MBN 19* British Napoleonic Infantry, stove pipe shako, attacking (again, some attention to headgear needed).

Imperial Guard Cavalry:

• Cuirassiers, Guides: NCF 11 Cuirassiers.
• Carabiniers: MFN 16 Carabiniers.
• Dragoons: NCF 6.
• Lancers: NCF 12.
• Chasseurs: NCF 4.

Imperial Guard Artillery :

• MFN 9*: Napoleonic Guard horse artillery and French FPW guns.

Line Infantry:

• In campaign dress: NCF 1, NCF 2 ( otherwise try MBN 19* British Napoleonic Infantry, stove pipe shako, attacking).

Piedmont

Infantry:

• Line and grenadiers: Nothing is really equivalent here. If you want a shako close to the Italian ones, try MBN 19* British in stove pipe as above. If you prefer the greatcoat use French infantry NCF 1 and NCF 2.

Artillery:

• MBN 26* British foot artillery (with French FPW guns).

Austria

Infantry:

• Line: If you want to depict Austrians with rolled greatcoats: Prussian Jaegers (NCP 3) and / or MPN 1* Prussian musketeers. 
• Line units with "bonnet de police": French Guards (NCF 8, NCF 9, you have to cut off the pompons).
• Some Napoleonic British infantry attacking in shakos MBN 19*(and MBN 22*)may also be used, with some attention to headgear.
