Tell me more about the current single player meta. Show me an optimal yet lazy template and doctrine there is available (something that doesn’t require me to micro).
Well it depends on what mod you're playing, what country you're playing and whether you have to go early war or not.
As far as line infantry goes you want primarily 16 (some people advocate for 18 width) pure inf with field hospirtals, aa if your enemy has air superiority. Most people don't push with line inf but if you're going to push then adding support arty is a good idea.
For offensive infantry you want to mix marines with mountaineers where possible (replace mountaineers with rangers if you're fighting in the jungle mostly) You want 7 units of marines and fill the rest in with mountaineers since mountaineers have the hgihest stats and 7 units of marines is what you need to get the maximum river crossing bonus. go for 34/35 width and remember to place one line AT espeiclaly if your enemy will have tanks (but the ai doesn't build good tanks anyways so might be a moot point)
Line arty, light tank recon, medium flame tank support, pioneers and field hospitals are good. You could replace one of them with signal companies
Since you want a braindead build I'm not going to bother with pure marine/ amtrac/ pure mountaineer divisions.
With tanks there's an debate in the multiplayer community as to whether heavy tank destroyers, medium tanks or heavy spgs are best. I'm not gonna bore you with the details since hard attack hardly matters in sp anyways. Just go for 36/38 width and replace your motorized with mechanized with you get them. Logistic companies, medium flame tank suport and field hospitals are must haves.
For doctrines, it is generally agreed upon that grand battleplan and superior firepower are the best since the grand doctrine rework. If you're using grand battleplan remember to make battleplants ahead of time to max out your planning bonuses.
Tank builds generally want individual execellence, self propelled support, tank destroyer force/ armored spearhead and grand assault. In sp go for armored spearhead since tank destroyers are unecessary
inf builds generally want assautl inf, siege artillery/ field engineering (depends on if you're buildng super heavy arty) armored infantry support and either grand assault or desperate defence.
For regimental support heavy weapons company are great for defenensive line holding inf (your 16 widths) and for offensive infantry/ special forces you want motorized heavy weapons teams because it gives you more breakthrough
That's the gist
