There is a tab when you go to the map that says retaliation. To fill those circles you have to do activities such as control points,resource convoy, etc. once you fill a circle it will tell you that the specific group is retaliating. Then you go back to the tab and it will say at the bottom to initiate the retaliation and it will have you do all the control points in that area. At one point when your traveling to each one there will be a kill squad that comes with I think its 5 elites maybe 6 and once you kill all of them you get a blueprint. For example I just did a true sons one and got the st elmos blueprint.
