thanks for the response my original question after i just read it sounded really dumb my main concern was after i buy the a10c module i was unsure if i would have the ability to use it in any campaign without buying an additional campaign pack or what not i have FC3 and combined arms (never used ca have no idea why i bought it haven't found a use for it as of yet) but i enjoy the fc3 missions with the a10a and the f15 so just looking for a cheap option after i get the a10c module for good missions but as stated above i might just buy the training pack at first because i hear its rather tough to learn i really enjoy learning the ins and outs of the aircraft tho thanks for you guys opinion and thoughts
