What does the "Disciplined" button do in battles?

[defendurname]

I thought Disciplined was just a tooltip to show the passive buffs a unit has but in battles they have a button called "Disciplined". Are there any reasons why I should ever turn it off?

It is representing passive disciplined bonus, so unit losses cohesion slower than units without it. Its enabled automatically, and you should not disable it. just leave it as it is..

to make this less confusing, in next version, former "Disciplined" attribute, will be renamed to "Trained" as it actually makes unit able to rally from rout, while actual passive ability "Disciplined" will handle the reduced cohesion loss.

Similarly, all possible tooltips related to former fatigue will be reworked as they are no longer valid. Instead, they will have appropriate tooltips mentioning what they now represent.
