We haven’t had too many user made campaigns for the Hog. So this is nice looking one (The Enemy Within) with plenty to challenge a Hog pilot.
This is a 7-mission, story driven campaign taking place in 2015 in Georgia. A squad of A10s is sent to Kobuleti by NATO in order to help the Georgian government tackle the rising terrorist threat...

This video shows some of the action. Note, the weather is pretty bad in this mission!
