They are all inactive right now. When I started the tedious process of building my fighter count up I activated all of them. And retired all fighters when from the others camps when my main was at max. I think that it is a total of 6 camps.

I am on my phone right now, so I don't have access to them. However I ran a second camp named 'barbarolo' and a third named 'Kabul FightForce' back in the day. The barbarolo one was by far the most successful, I think one of my guys had a top 10 ranking at one time.
