Yes, correct. Without the generator, it's just a gas turbine starter (Like the Viggen's GTS) used to start the main engine. If the GTS is driving the generator, it will be an APU, and it will no longer start the main engine.
It's been like that for many years. It kinda drives me crazy in the A-10C :) I have to adjust the HUD brightness all the time to MAX. My OCD is way too strong I guess. I wish I could modify that thru the .lua.
Thanks Vincent for the pics, I don't have any doubt that the BRU-33 can be used to carry and release LGBs (e.g GBU-12 and 16). But I am not sure about the JDAMs. I would like to know that as well. :)
