This increases the amount of Troops Limits the AI can build, increase it almost by x2.(All Lords), it only increase the limit and the likelihood if them gathering bigger troops before attacking. As well as the amount of the troops they used for defence. Vanilla is just too Easy by Default once you take out all of their ranged units. While this mode increase the amount of troops AI will gather (it still takes time, it actually will give you plenty of time to prepare for Defence)

Late game once you have access to Knights the AI stops getting stronger and its just so easy to faceroll all of them with no challenger

Richard now Fields Archers and Pikeman, also starts with Pikeman.
Templar now Fields Archer
Templar uses Knights for Defence, not just for Siege 
Wolf, Templar and Richard uses Pikeman also for patrol
Saladin, Wolf, Templar and Richard can build more houses and increase building limit. 
Richard, Saladin, Wolf and Templar Builds more Wood Camps, Stone Quarry and Iron Mines. As well as weapon workshops.
Slave King now uses Slave Driver as Response Force and Slaves instead of Archers
Slave King starts with more Slave Drivers and uses them more in siege and harass. In vanilla he only spam a maximum of 2 Slave Driver is too low
Emperor now also uses Swordsman, he's a Emperor, why would he only use Peasants?
Duke now uses Man at Arms
Princess uses Arabic Swordsmans, instead of Man At Arms mostly
Sultana uses Assassins for Defence, Siege, instead of archers during defence and emergency

To Install
M:\SteamLibrary\steamapps\common\Stronghold Crusader 2\assets 

I already merge the mod with the Building and Units Increase Mod. Since its a must. If you have that installed please delete it else it will cause conflicts and cause this mod to not work. Vanilla you only have 112 units limit or close, with 100 buildings buildable. Here you have 2000s as limit

How to do a quick test to confirm this mod works - On Skirmish If Richard spawn with Pikeman mod is working. and you should have unit limit above 500 or close

Vanilla Saladin, Richard is a joke, that's why this is important to buff them. Literally poster boy, but he's so weak. Also if you gave AI Supplies and infinfiite gold they still refused to spam armies nor make use of it due to AI Limits and the amount of troops they can field that's limited by code

on your assets folder of your Crusader 2, put assets.v and replace it
