If you're going to get serious about CAS for the troops, a gun has some very significant advantages.
1. Accuracy. Granted, I was a lot lower and slower, but I shot bad guys off of the 5-meter wire around an outpost with a SUU-11 minigun with no problems. I've done that with 5-inch rockets too, but I didn't feel as confident.
2. Controlling ammo expenditure. If you are out of heavy ordnance, or if you need to stay on target and keep the bad guys at bay while you are waiting for more air support, the use of just a few rounds on each pass keeps you in the game, and keeps the troops covered.
3. If you have a force, either bad guys or unknown, advancing toward your troops, nothing draws a "line in the sand" (or water, or rice paddy) like a few hundred rounds in front of them. No harm, no foul, very clear message.
On top of that, there's also the fun factor. You pull the trigger, and you can watch the magic show right before your eyes. :icon_tong
I see your points, and I can see them from a helo perspective. But from a fixed wing aircraft? I don't know specifics about employing the gun, but I'd imagine it puts you a lot closer to AAA, and what happens to your RCS when you start punching holes into an aircraft?
I'm not a hater of having a gun in any way. I just don't see not having one as a significant loss of effectiveness. It's a tool, useful at times, but is it worth it? Esp with the weight issues the F-35 has.
