As someone who isnt playing on BR, I can say that Ive seen a capture point on all of the open field battles Ive played. I think it was because the enemy army was on forced march, as the capture point was on their side of the battlefield and I had to take it.

Unfortunately though, I dont know if thats true, as one of the mods I have deletes the spinning circle animation that would be underneath an army if it was on forced march...
