I need a better Venetian stack

[Amon_Zeth]

I usually go into battle with the following stack, as the Venetians.

1 General
1 Caroccio Standard
6 Pavise Crossbow Militia
6 Venetian Infantry
6 Feudal Knights

I am going to restructure this army, in order to include artillery so as to better siege my enemies. While I'm at it, how else should I change up my usual stack of soldiers?

While Milan is different from Venice, it is only so slightly, so I'll tell you what I used as Milan..

I basically made up my army of 1-2 generals, depending on whether I can find some troops to occupy another general with or not.
Secondly, I use cav heavy armies, so usually 4-6 knight hospitaller + 4 feudal knights.
Add to that you'd want 2-4 dismounted feudals and some spear infantry such as armored sergeants or merc spearmen.
For ranged I'd then suggest mounted xbows for speed or merc crossbows for stationary. Genoese xbows work as well, but tbh I actually never seen any for hire (maybe after gunpowder age?), which is why I suggested mercs.
Caroccio may give you minimal morale boost but its too few people and I found them to be overwhelmed by rebel peasants already so I wouldn't recommend using those except for a defense.
For artillery, you'd want ballistae to take out enemy artillery and trebs for hitting people and walls. I found the AI using trebs are very very accurate, more than catapults even against troops and a lot more devastating. I suppose 1 treb and 1 ballista should really be enough. For sieges you got rams, towers and ladders anyway to scale those parts you don't want to break the walls of.

Feudal knights mounted or dismounted ?

Feudal knights mounted or dismounted ?

Mounted, otherwise I'd have no cavalry other than my general.

Hmm, 6 Crossbowmen seems a bit excessive. I would tone it down to three or four, and add in some Feudal Foot Knights in their place The Venetian Infantry are great but I find the foot knights even better. Also, 7 heavy cavalry is great, but I usually try to include some light cavalry (mounted sergeants; broken lances are heavy, arn't they?) in my stacks for performing lightning-flanking manouvres or chasing down routers.

I typically use my general, 4 VHI, 4 Italian Spear Militia (Or pike militia), 6 Pavise Crossbowmen, two units of cavalry, and three artillery pieces.

I did one Venetian Vh/Vh campaign.

In garrisons I used 6 crossbow militia, 11 peasant crossbows and 3 militia cavalry. The Venetian militia cavalry is a great value, it is FREE in towns, $150/turn out of a town, has good stats and gets +3 valour if produced in a town with Merchant Headquarters. It gets 3 more valour if retrained in horse Guild Headquarters! It seams it earns valour very fast, in no time it has 3 gold chevrons. When besieged I sally out first with 6 crossbow militia, next with 6 peasant crossbows and when the AI runs away finish it off with the militia cavalry.

My siege army (sieges only) was a general, ~2 trebuchets or guns, ~6 Venetian infantry, ~6 hand gunners or Venetian armoured archers.

My field army (field battles only) was a general, ~10 crossbow militia, 7 spears and 3 militia cavalry. The Venetian crossbow militia is on “stand and fight”, they have good defence.
