I understand that squadrons at distance 1 of each other are engaged, my question is: at what point of movement does engagement kick in?
1- End of movement, so you could potentially fly past a squadron?
2- Instantly the moment distance 1 is reached, meaning a screen of squadrons could prevent you from reaching the inner ones (is that the point of the Rhymerball, for instance?)?
3- When you go to move a squadron, you check to see if they're eligible to move?
Basically, can I fly a squadron past an enemy squadron, or would they immediately stop at distance 1?
