Squad with formation

Hi,
I’m not good in blueprints. I have such question.
There are units that follow the player. I need to do that if one unit sees another, they are united in the squad. If there are two squads, they are also going into one. Units formation in squad needs to be a circle (for example). It is necessary to squad continued follow the player.
I have not found nothing in the standard functionality . In what direction should I look?
Sorry for my English :slight_smile:
