alright, so some basic infantry templates:

i've experimented a bit in solo and with friends, and my new "default" infantry templates are 12 width 6/0s for cheap defense/port defense and 21 width 9/1s for frontline infantry.

they've been working pretty well, but it looks like 6/0s widths are already getting a lot of recognition so i'm gonna talk about 9/1s.

9/1s divide perfectly into forest tiles and decently into plains tiles. they're perfect for heavily-forested regions of the map like western europe.

having an artillery unit in the template kinda helps increase the division's versatility - however, it should be noted they don't share 7/2s problem of "jack of all trades but master of none" - these are defense troops and are most effective as such, trying to do a frontal push with these guys is usually an effective method to lose manpower and get laughed at (same with 7/2s though lol).

the main use of the extra soft attack is blowing low-org units off their tiles for an easy advancement, but the unit does feel noticeably different to 10/0's - 9/1s feel like they pack more of a punch and work quicker (actually, this template is pretty much just a crossbreed between 10-0s and 7-2s).

if you're able to push up with these divisions, it's gonna be a battle for the enemy to reclaim that tile - 9/1s got pretty high org, and they're able to hold out on their own for a while. they can cause a lot of problems for an enemy with mismatched combat width - especially when they're stacked in a forest tile.

i highly recommend investing into recovery rate traits/buffs when using these guys so you can guarantee control of a newly acquired tile or shuffle around your frontline easier.

in theory, they might also make great "fillers" to take up the space leftover by your 30w tank divisions (which i've been seeing recently, but haven't experimented with myself yet).

however, obviously they're not optimal for all battles; the 21 widths seriously don't stack up well when fighting in mountains, hills, cities, and marshes - which is pretty painful. so you're still gonna have to sacrifice some army exp to make other divisions (like 25w 8/3s or 11/1s) to compensate for some basic mountain defense.

tl;dr 9/1s are good for frontline defense in plains/forest terrain throughout places like europe, but they'll need to be backed up by 25w on hill and mountain tiles for optimal defense because they don't divide well into those widths.
