Controversial point here, but is FAC ever really a viable role in this day and age? All good fun in training, but I couldn't see us ever deploying PC-9s or their replacement to be marking targets over any kind of battlefield these days.
AT-802U prob be better. Pull the wings off and stuff it into a C130 or C-27J and send it anywhere around the world in a few hours.
2 seat, 15 hard points, lots of cameras, 10 hours endurance, .50 cal. GAU-19/A three-barrel Gatling guns, dual M260 7-tube rocket launchers, and 500 lb. Mk-82 bombs, hellfire etc.
