1. It is enough to hav barracks to produce infantry but offices are better choice
2. 6 infs is enough for morale 25 , you cna check how many untis you need looking at province description and checkign rebelion chance. Deduct 1 infantry at the tim to lower garrison and check how this will influence the outcome
3. there is strategy that says to go full red bar to maximize ie iron production on the expense of wood. It is good strategy at the beggining when you have a small country and morale is easy to fix.
4. But watch out - givign maps to everyone means that yoru opponents can have access to screenshots
5. level 1.5 forts hide units so if you just want to hide troops - stop production when you reach that stage
6. learn waht is flwoer, tercios, hwo dmg is spread and applied and what are cap limits on every unit. Ie 40 infantry has exactly same dmg as 10 000 000 infantry. Learn about dmg delimiters.
7. Fots can also increase resources produciton as they rise morale of province. The mroe morale you have- the more you produce adn the bigger bonuses ports, ailways and factories give you.
8. Yeha no poin atatckign first. Wait for other to weaken Ais or other nations and join 3rd or 4th to be safe. Small Ais will be useful laetr whe nyou need morale boost for yoru 1000 provinces and you will need AI capitals for that.
9. Read al lstrategy topics, especially those from top fghting players as you have confirmation they know how to use them on the battlefield. You ccna check also ytube resoruces from Zolokin ( basics adand medium) , DruzusNero (me - advanced) and coupel of other guys.
10. Learn to fight . The more you fight - the betetr you get with it. Rise challenge by fightign withotu freinds, support, GMs. later make it even harder attakcign bigegr players and limittign yoru activity. This way you will peerfect yoru own style.
