OK folks, I know this has been brought up many times, in multiple threads, but since you are asking for my wish list:
1. Large Caliber (88mm or higher) mannable ack at fields. Face it folks, 37mm just ain't enough to stop the vulchers. I'm not asking for a CV's worth of AAA at each small field, but a few mannable 5" singles (or the 128mm german late-war equivalent), or even 88's would at least give one the possibility of hitting a 8K buff intent on blasting all the fighter hangers to oblivion. It's not like were asking for some radar-directed uber cannon here, just the ability to be somewhat dangerous to a set of lancs hedgehopping over the field laying 1,000lb bombs all over my nice clean field.
Those of us intent on ground attack will still be coming in to de-ack, but at least it will be a little bit scary knowing that I can get an 88 shell in the kisser as I'm diving in.
2. Related Wish: ACK TOWERs. If you do any reading up on these, you can find examples of the various types. They range from windmill sized (and disguised) quad 20mm towers all the way up to the city defending behemoths mounting 4 pairs of 128-mm guns (as well as a large number of smaller mounts). These babies would make ground attack missions a true gut-check.
Check these out:
http://en.wikipedia.org/wiki/Flak_TowerFurballers can still have all the fun they want, they just need to stay a few miles away from the field to be safe. Bombers and Ground Attack guys get a more-realistic idea of what it was like to face a mass of AAA when going in on a target. Large caliber ack guns don't stop attacks (just ask anyone that has watched their CV sink), but they should help prevent vulching and you get an added bonus in vehicle defense as well.
My $0.02 worth (again).
