Crusader Kings 3: how to raid in CK3

Raiding is a Crusader Kings 3 mechanic that returns from CK2 and allows Pagan or Tribal ruler types to raid the lands of other rulers. This works a little differently to standard warfare in CK3, but you'll still need to jump through a few hoops before going Viking on your neighbours. Crusader Kings 3 raiding is a lot more difficult than in CK2 with longer waiting times for raids and more costs associated with raiding, too.
In addition to these costlier, more time-consuming raids, you will also find that standing armies are a lot stronger than in CK2, so your best bet as a small raiding nation is to only attack the smallest states you can find. You can check this by looking at enemy territories and hovering over their banner to see how many troops they have at the ready. You can also check how much loot you'll get in by hovering over an enemy banner, so picking the maximum loot from the smallest army is the way to go.
The first thing you need to do to raid in CK3 is raise a raid army. To do this you'll need to head over to your military tab and either select a rally point near an area you want to raid, or create one. Once you've done this, click the rally point, which should open up a new tab at the bottom right of your screen - the key here is to choose 'raise local raiders'. Only the Norse can perform sea raids, so for any other rulers you will need to make sure the journey can be made on foot. You can also raise all your available soldiers as raiders by clicking the 'Raise All as raiders' button at the top of the Military tab.
