It's a feature suggestion and showcases how easy to create something like that. If you have forum account, go there to support idea if you are supporting it, so that TW can take an action before it's too late ( while game is still in EA )

About Video:
The reason why you are seeing some soldiers are moving while some of them are sleeping/sitting is that ones that are awake and moving are actually camp guards. Once they spot your soldiers from a distance, your position is revealed to the enemy and they immediately try to notify all other soldiers to get into battle formation.
Some tents are causing issues for AI when they need to pathfind, but this can be easily avoided if I had time to create new prefabs.

About Idea:
A simple ambush mechanic demonstration for Bannerlord. I made the entire thing in ~4 hours so it's not perfect but the overall idea is very fun to explore. I'm not planning to release it as a mod.

It's adding camp and ambush mechanic. Camp mechanics will allow players to train their troops with the cost of being stationary. In ambush, players can set up an ambush environment for other hostile parties. The success of this ambush relies on traits and skills. Upon successful ambush, you can attack the enemy army's camp and win even while outnumbered.
Depending on certain conditions ( crouching, night-time, distance and visibility ) they can spot you easily on the battlefield or they can see your troops when it's too late. While you are undetected, they won't realize that your troops are in the battlefield and they will continue their disorganized position.
All "camps" are automatically generated hence the content is random and dynamic to troop culture and count (for example, looters won't have outer palisades ) and can be generated in all terrains.
