I guess I wasn't clear enough. Why now, when there are almost no known super powered individuals, is she recruiting a team of mostly crazy but talented normals to do black ops instead of you know.. Turning to the government's black ops teams. She doesn't have the reasoning that they are needed to deal with super powered threats or political enemies that they can't touch with normal troops. It can't be to stop Superman. None of the Suicide Squad could even touch him. Batman? Maybe. But why recruit his rogue's gallery, when he probably put them in jail in the first place. There just isn't a reason given yet why they would need the Suicide Squad, or even why someone would think up the idea. The only thing I can think of is they plan to send them on literal suicide missions, because they are 'expendable assets'. For anything else, the ordinary military could do what they can do, almost certainly better and with less risk involved.
