Quick Overview

The command ai_army_tick in Europa Universalis IV forces the Artificial Intelligence (AI) to reassess all ongoing army movements.

Essentially, it instructs the game's AI to rethink its current military strategies and tactics by reconsidering the movements of all its armies on the map.

This command could potentially change AI's decisions related to army positioning, planning attacks, or defenses.

In-Depth Description

This command in Europa Universalis IV (EU4) is an AI function which is primarily used for debugging. When you write ai_army_tick in the command console, it will force the artificial intelligence (AI) to reevaluate all army movements currently being executed in the game world.

In other words, it will make the AI reconsider its decisions regarding military maneuvers, such as whether to adjust the direction of its army or change its strategy, based on the current military and political state of affairs.

It can be helpful if you have modified some code or a script in the game and want to see how the AI reacts immediately, without waiting for the AI to naturally review its actions.

For instance, if you've changed the AI's weighting parameters around how it chooses destinations or targets, this command can instantly trigger a reevaluation to check the AI's new decision-making process.
