Cannons.
Calvary obviously, but you knew that.
Your own grenaders.
infantry
you usually want your Cavalry to have Flanking
Except that you usually want your Cavalry to have Flanking and your Cannons to have City Attack - both which leave them vulnerable to Comat I/II Grenadiers - plus you generally don't want those units to defend.
- Redcoats should shred the AI grenadiers.
If you're defending against ai grennies machine guns will stop them dead in their tracks. If you're attacking them cavalry or cannon + whatever.
grenadiers are a non-factor in 99% of my games
Cavalry is fine "defending" vs. them if really needed, btw who said you want flanking?!?
You want pinch and if the AI has made it to cavalry too maybe even the nice horse symbol (can't remember the name ffs lol, 25% vs. mounted...) because there might not always be a rifle along with the fast moving cavs.
I believe it's called "formation". Also flanking 2 cav has amazing survival rates when attacking mixed stacks, you're much better off attacking enemy stacks than waiting for them to hit you. If you attack a stack with cavalry they do extra flanking damage to their siege. So if you let their SOD cross your borders and then hit them with cannons plus a few cavs, they don`t stand a chance. But if you have cannons and cav you should really be attacking the enemy and not trying to defend yourself.
Try splitting your stacks and advancing on a city simultaneously from two directions. Apart from that, I use cannons to weaken grenadiers then send in riflemen, I tend not to use cavalry as I generally beeline infantry.
On an entirely different note, I got absolutely battered by a stack of cavalry attacking my riflemen and cannon yesterday , I must have lost 25 cannon and 20 odd riflemen to the same number of combat 1 and 2 promoted cavalry.
This was one of three stacks I had moving into enemy territory, so no major harm done, but I did have to do some major reorganisation of my garrisons to deal with the now, unopposed, 30 odd injured cavalry units marauding through my interior, just as well I had a few infantry and railways to get to the scene of the crime quickly.
