Not being a ground pounder, I can not say for certain but it does seem to me that it would be much more accurate for an aircraft moving at the speed of the A-10 than it would be for a fast moving f-35 to hit accurately a small target without hitting long or short.. Kind of like the difference between shooting a deer that is walking vs one that is going balls-to-the-wall(been there, missed the shot !). Can the f-35 carry the same amount of ordinance as the A-10? Can it remain on station as long as the A-10? If you are a grunt, who's actually been there and done that, which would you rather have covering your back?
