Question: Recon button

[Nemo84]

Hello
I'm new here!

Question:
I can not find info in the manual about the Recon button! How does this and what is happening there?

Thanks!

I think this is about Recon Spotting. If it is a Recon unit and you choose this action there is a chance this unit will spot concealed enemy units. 

Seems this should be explained in the manual along with some idea of how likely they are to spot the enemy.

Ah, so that's what that button does. So which units are Recon units? The ones with those tiny binoculars in their sidebar icon?

This should not only be in the manual, but probably also in one of the tutorials. It feels like this is a major game changer for an army on the offensive.
